This is a tiny rechargeable Lithium ion polymer battery that fits perfectly behind the TinyDuino Processor board to power your projects. The battery has a capacity of 150mAh at 3.7V, the voltage can range from 4.2V when fully charged to 3.0V when completely discharged. The battery includes protection circuitry to protect the battery from over charging or completely discharging.

This battery includes a micro JST SH connector, which is used on TinyCircuits products that support Lithium ion batteries. 

• Dimensions: 20.0mm x 20.0mm x 5.0mm (0.787" x 0.787" x 0.197")
• Wire Length: 12.0mm (0.472")
• Weight: 3.77 grams
• 3.7V, 150mAh

The USB TinyShield lets you connect your TinyDuino via a micro-USB connector. It uses the very popular FTDI FT231X USB to Serial converter IC (as used on most standard Arduino models). Using this board allows you to download new sketches via the Arduino IDE to your TinyDuino, and also allows you to add USB communication capabilities to your projects. This board supports RX and TX status LEDs so you can visualize the serial traffic to and from your TinyDuino.

The USB TinyShield is available in two variations on where the USB cable can plug in. Most TinyShields are square, which makes plugging in the USB cable simple to do at any angle. However, there are some TinyShields that are not square, so depending on their dimensions this can make plugging in the USB cable difficult.  For example: the WiFi TinyShield is long, so a side mount version of the USB connector works best for this. The TinyScreen is wide, which works best with the top mount version of the USB connector.  

• Side USB Connector - The micro USB connector will come out the left side of the TinyDuino stack.  This works well for all TinyShields, except the TinyScreen and the Proto Terminal Block TinyShield.
• Top USB Connector - The micro USB connector will come out the top side of the TinyDuino stack.

• By default this board will supply +5V to the TinyDuino stack.  It is possible to change this to only output 3.3V instead (with a max current of 50mA), by removing moving the 0 ohm resistor from the R4 position to the R5 position (requires advanced soldering skills).
• Revisions of this board before Rev 6 had a breakout for an Atmel ICSP connector to allow for In-circuit programming using a ICSP programmer.  These connections are no longer present on this board but can be accessed using a Proto TinyShield
• This board also uses the DTR line from the FTDI IC to support the auto-reset function when a new sketch is downloaded to the processor – eliminating the need for you to hit the reset button to reprogram your TinyDuino.

This proto board brings all of the TinyShield signals out to a point that you can solder to. All of the signals are marked and are spaced with 0.1″ spacing (same spacing as on the standard Arduino Uno), so a standard 0.1″ header can be used if desired.

This proto board can be ordered with or without a top stackable connector. By default, a top connector is not needed since the standard method is to use this proto board as the top board in a TinyDuino stack for the easiest access to the signals. However, when this board is ordered with the top stackable connector, it can be an inner layer of the TinyDuino stack (which can be useful in some projects).

Originally Launched on Kickstarter!

TinyScreen is a beautiful color OLED display for your TinyDuino system. Create video games, a video player, or your own smart watch using this Tiny OLED screen! The screen is 0.96" diagonal with a resolution of 96x64 RGB pixels, each with 16-bit color. Since this is an OLED, there is no backlight needed and the screen is very bright with excellent colors. Four buttons are located along the side of the screen to allow for user input - like for playing games or creating menus for your projects (like is done on the TinyScreen Smartwatch project). The screen has a built in IO expander over I2C for control signals and button control, which eliminates using extra pins on the TinyDuino for this.

The screen uses an SSD1331 driver for the OLED display, and we have a highly optimized and easy to use library for this which supports both the OLED screen and the buttons on the board, even allowing for 20FPS+ video playback from a microSD with the TinyDuino. It's also very easy to create your own projects to display text and graphics, or create your own tiny games.

The TinyScreen is also available with an alternative device address, which allows two TinyScreens to be used on the same TinyDuino stack when used with a Ribbon Cable Extender or with a TinyScreen+.

The Dual Motor TinyShield allows you to drive two independently controlled DC brushed motors from your TinyDuino. Create your own tiny robots or drones! Using two of the super miniature but very powerful 2mm x 2mm TI DRV8837 Motor Driver (H-Bridge) IC, this shield will allow for up to 1.8A per channel and operate motors between 1.8 to 11V. This TinyShield includes a built in motor controller to make driving motors simple and uses the TinyDuino I2C interface - saving GPIO pins on the TinyDuino processor for other tasks. An easy-to-use Arduino library is provided to control this..

TI DRV8837 H-bridge motor driver

• Low MOSFET On-Resistance: HS + LS 280mOhm
• 1.8A Max Drive Current (Recommend 500mA max)
• 1.8V to 11V Motor Operating Supply Voltage Range

TinyDuino Power Requirements

• Voltage: 3.0V - 5.5V 
• Current: 5mA (Logic only)

Pins Used

• A5/SCL - I2C Serial Clock line
• A4/SDA - I2C Serial Data line

Dimensions

• 20mm x 20mm (.787 inches x .787 inches)
• Max Height (from lower bottom TinyShield Connector to upper top TinyShield Connector): 5.11mm (0.201 inches)
• Weight: 1.62 grams (.06 ounces)

• While the DRV8837 supports 1.8A @ 11V, we highly recommend operating under 500mA @ 5V per channel unless you have some really good heat sinking in place.
• Up to 4 Dual Motor TinyShields can be stacked together in one TinyDuino stack. However, the I2C address needs to be different for each TinyShield. This can be changed with resistors R1 and R2 (soldering is required for this).   
• By default, the motor power supply input connection is connected to the VBATT connection on the TinyDuino. Therefore, you can run your TinyDuino and the motors off the same battery when it's plugged into this TinyShield.  However, when using this, be sure not to exceed 5.5V on this power input or it will damage the TinyDuino circuitry.  If a higher motor voltage is required, you can remove resistor R3 which will allow you to run the motor voltage independently from the TinyDuino logic voltage.   
• Even though the motor driver can support 11V at 1.8Amps, we do not recommend using more than a 5V motor at 500mA due to the small size.  
• Be sure that your power supply is sufficient to operate these motors as well as your logic – batteries are the best. If you are running both the motors and the logic off of one power supply, we recommend avoid using a switching power supply as the transients caused can potentially damage items connected to the logic side.

This TinyShield lets you add a battery-backed real-time clock (RTC) to your TinyDuino projects. This lets your project keep accurate time even through the TinyDuino being reprogrammed or power losses. It is based around the Maxim DS1339 RTC and supports counting in seconds, minutes, hours, days, date, month and year with leap-year compensation (valid up to 2100).

The RTC has two time-of-day alarms that can be set to wake up the main TinyDuino processor from sleep (very useful in long term data logging applications) and will automatically switch to using the backup battery upon power loss. The backup battery is a rechargeable Lithium coin cell which is soldered onto the TinyShield and will keep the RTC time for 2.5 years before being recharged. Trickle charging of the backup battery can be enabled using a software command.

Our Bluetooth Low Energy (BLE) TinyShield allows you to connect your TinyDuino system to any compatible iOS or Android (4.3+) device using Bluetooth Low Energy (also known as Bluetooth Smart and Bluetooth 4.0). This technology is great for low power sensors and accessories and works with most modern phones without the need for jailbreaking on iOS devices. This TinyShield is based around the popular Nordic nRF8001 chipset and allows wireless communication up to 10 meters away. The TinyShield also Includes power supply and level shifters on the board, so you can run your TinyDuino from 3.0V – 5V.

The Nordic rRF8001 chipset only support slave mode which allows it to connect to master Bluetooth LE devices (like a smartphone), however it cannot connect to another Bluetooth LE slave device (ie, two of these boards cannot communicate directly with each other).  If you need master mode as well, take a look at the Bluetooth Low Energy TinyShield Bluegiga version.

Note: This product is for ADVANCED USERS, and requires that the user develops their own iOS or Android BLE app in order to use this.

• The TinyDuino processor board included has the coin cell option.  The coin cell (a CR1632) is not included in the kit.
• The coin cell battery can only be used for low power applications and cannot be used to power every TinyShield (such as the TinyScreen or the WiFi TinyShield).  In these cases, plan on using the Lithium battery version of the TinyDuino Processor.    
• A micro USB cable is not included in the kit.   

Our new Bluetooth Low Energy (BLE) TinyShield combines both master and slave modes into one module! This TinyShield allows you to connect your TinyDuino system to any compatible iOS or Android device using Bluetooth Low Energy (also known as Bluetooth Smart and Bluetooth 4.1). This technology is great for low power sensors and accessories and works with most modern phones. This shield acts as a drop-in hardware and software replacement for NRF8001 (Nordic) TinyShield projects. Unlike previous BLE TinyShields, your Arduino sketch code can modify your module's connection parameters directly.

This TinyShield is based around the BlueNRG-MS chipset by STMicroelectronics, which comes in the SPBTLE-RF module. The TinyShield also includes power supply and level shifters on the board, so you can run your TinyDuino from 3.0V – 5V.

Since the SPBTLE-RF module supports both master and slave modes, you can communicate both with a Bluetooth LE device (i.e. a smartphone) and another BLE TinyShield or other BLE module with slave mode. If you have one of our previous BLE models, a BlueGiga or a Nordic, it can communicate with those as well.

The 433MHz long-range radio TinyShield is based around the very popular Silicon Labs SI4432 radio transceiver - the same transceiver as used by the HopeRF RFM22B module.  The TinyShield is set to operate at 433MHz and can transmit at up to +20dBm and is very easy to use. This transceiver allows for long-range communication between radios and is designed for an open field range of up to 500 meters, which makes this great for long-range sensors of RC control (like drones and vehicles).  

A U.FL antenna connection is included on the board, along with a 433MHz whip antenna.  The TinyShield incorporates level shifters and a local power supply to ensure proper and safe operation over the entire TinyDuino operating voltage range up to 5V.
