This Sewing Kit with Conductive Thread has the bare essentials to get you going on your next wearable project!

This kit includes the following items:

• Conductive Thread - Available in either 16 / 32 / 64 ft. 
• Two sewing needles - Hand sewing needles, steel and nickel plated. 
• One needle threader
• Two buttons
• Additional thread - 3ft. of each color Pink, Blue, Silver, Brown, White, Black. 
• One safety pin

• Conductive thread is available in either 16 / 32 / 64ft. 
• Conductive Thread is made from Stainless Steel Fibers
• Conductive Thread Resistance: 28 Ohms/ft

• This thread can be slightly more difficult to work with in close, fine conditions. Our resident E-Textiles expert suggests waxing the thread for hand sewing, as this should take care of any 'hairy thread' issues.
• Since waxing is impractical in machine sewing applications, avoid sewing close connections by machine as the 'hairs' could potentially short across small distances.

Spun from stainless steel fiber you can use it as a creative way to connect various electronics onto clothing projects. These spools are a great way to get into wearable electronics without a large upfront cost and come in large enough quantities to not be afraid of making a few mistakes.Great for artists, crafters, designers, hobbyists and robotics enthusiasts alike.

What sets this thread apart from others is the fact that it's actually spun from stainless steel fibers (as opposed to plated silver) and doesn't have a Nylon core. This means that while it may not be easy to solder to, because it's stainless, it also won't burn up when you touch it with a soldering iron. Perfect for your next project as it allows wearable clothing to remain wearable and washable!

The TinyLily Mini USB Adapter adds USB support for the TinyLily Mini via a micro-USB connector and uses the very popular FTDI USB to Serial converter IC (as used on most standard Arduino models).  A small 5-pin plug allows connection to the TinyLily Mini programming header.  Using this board allows you to download new sketches via the Arduino IDE to your TinyLily Mini, and also allows you to add USB communication capabilities to your projects.

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 a reset button on the TinyLily Mini.

Power is also supplied from this board to the TinyLily Mini, and there is a resistor jumper option on the board to select either 5 Volts or 3.3 Volts (this is set to 3.3V by default).

• FTDI based USB Com port
• USB 2.0 Full Speed Compatibility

When TI came out with the world’s smallest DC motor driver chip, we knew we had to build a board around it. Based around the 2mm x 2mm TI DRV8837 Motor Driver (H-Bridge) IC, this board is incredibly tiny at only 10mm in diameter, yet can drive a 5V 500mA motor!  (Note: Although the DRV8837 is rated at 11V at 1.8Amps, with the small size and small heatsinking, we do not recommend exceeding 5V at 500mA). 

The DRV8837 is extremely easy to use and interface to your favorite processor board (such as a TinyDuino, TinyLily or a standard Arduino), and uses a simple PWM to control motor speed, direction, coasting and braking. The board includes a bypass capacitors and all the I/O of the DRV8837 brought out to sewtabs, as well as heatsinking the chip to a large plane on the bottom side of the board to help with heat dissipation.

The TI DRV8837 has one H-bridge driver consisting of N-channel power MOSFETs to drive a DC motor or one winding of a stepper motor, or other devices like solenoids. An internal charge pump generates needed gate-drive voltages. There are internal shutdown functions for overcurrent protection, short-circuit protection, undervoltage lockout and over temperature. The DRV8837 can supply up to 1.8 A of output current. It operates on a motor power-supply voltage from 1.8 V to 11 V, and a device power-supply voltage of 1.8 V to 7 V. There is also a extremely low power sleep mode with 120nA sleep current.

• Washable
• Eight Sewtabs – 1.2mm in diameter, easy to use with standard conductive thread and needles
• Robust Gold Finish – makes soldering easy and is non-corrosive

TI DRV8837 H-bridge Motor Driver Specs

• Low MOSFET On-Resistance: HS + LS 280mOhm
• 1.8A Max Drive Current
• 1.8V to 11V Motor Operating Supply Voltage Range
• Seperate Motor and Logic Power Supply Pins
• PWM (IN/IN) Interface
• Dedicated Sleep Pin

Pins Used

• VM - Motor Voltage Input:  This supplies the voltage to the motor and can range from 1.8 to 11 Volts (high current connection)
• GND - Ground: This is the Ground return and needs to connect to the Ground for both the VM supply and the VCC supply (high current connection)
• VCC - Logic Voltage Input: This is the logic voltage input, and needs to be the same voltage as the system driving the motor controller (like the TinyLily Mini or a standard Arduino).  This will be 3 to 5 Volts if connected to an Arduino based systems (like the TinyLily Mini or the TinyDuino), although the full possible voltage range is from 1.8 to 7 Volts.
• SLP - Sleep Input: This signal can put the motor controller into a low-power “Sleep Mode”.  A logic-low “0″ will put the motor controller into sleep mode, a logic-high “1″ will put the motor controller into normal operating mode. If sleep mode is not needed, connect SLP to VCC to allow normal operation. NOTE: This must be connected in order for the motor controller to work
• IN1 - Input 1: This signal controls the Output 1 driver. A logic-low “0″ will set Output 1 to low, a logic-high “1″ will set Output 1 to high. If left unconnected, this signal is pulled down to a low-logic “0″ with an internal resistor.
• IN2 - Input 2: This signal controls the Output 2 driver. A logic-low “0″ will set Output 2 to low, a logic-high “1″ will set Output 2 to high. If left unconnected, this signal is pulled down to a low-logic “0″ with an internal resistor.
• O1 - Output 1: This is the Output 1 driver and connects to on2 side of the motor winding (high current connection.
• O2 - Output 2: This is the Output 2 driver and connects to on2 side of the motor winding (high current connection.

• Dimensions: 10mm diameter (0.394 inches)
• Max Height: 1.41mm (0.056 inches)
• Ultra-thin 0.61mm (0.024 inches) PCB
• Weight: .13 grams (0.0046 ounces)

• 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.
• Although conductive thread can be used for all the connections, for the motor and power connections it is highly recommended to use normal copper wire soldered into these connections due to the power levels involved. If conductive thread is used for these connections, keep these thread lengths as short as possible.
