TinyZero Processor Board

$ 24.95

DESCRIPTION

TinyZero is TinyCircuits' second generation processor board, adding performance upgrades and additional features to the original TinyDuino. TinyZero is based on the Atmel SAMD21 32-bit ARM Cortex M0+ processor (the same one used in the Arduino Zero) and provides a USB connectivity port, power management and battery charger in a single 20x20mm board. This processor board also has an optional accelerometer version, which adds the low power Bosch BMA250 3-axis accelerometer to the same board without increasing the size. We've kept our standard TinyShield expansion port, allowing for use of all of our current shields, and all 20 IO pins are available for use. Note: The battery is not included and is sold separately.

The TinyZero Processor Board is available in two variations:

Without accelerometer - TinyZero with all the features mentioned above, except the 3-axis accelerometer.
With accelerometer - TinyZero with a built in Bosch BMA250 3-axis accelerometer

Main Features:

Atmel SAMD21 processor (same as is used on the Arduino Zero)
More memory compared to TinyDuino (both Flash and RAM)
TinyShield expansion connector, built in micro USB connection
Power switch, regulator, lithium battery management on board
Precision clock crystal and Real Time Clock hardware built in, low power standby
Optional 3-axis accelerometer
Up to 10 ADC inputs, up to 10 PWM outputs, up to 16 external interrupts

NOTES

To send text to the Arduino IDE Serial Monitor, use the SerialUSB object instead of Serial
As can be seen in the TinyZero schematic and board files, the INT1 pin of the BMA250 accelerometer is only broken out to a solder pad on the bottom side of the board. This is the small copper circle labeled "INT1" next to the "BOOT" button. Because of this, a wire would have to be soldered to this pad and then input to the processor via a Proto Board TinyShield. According to the official Arduino documentation for interrupts, any digital pin except for digital pin 4 is usable for interrupt input to the TinyZero processor.
If you were able to upload a sketch to the TinyZero and now it does not respond, you may need to force this into bootloader mode. To do this, power off the TinyZero using the slide switch. Plug the USB cable into the TinyZero and your computer. Then press and hold the button on the bottom on the TinyZero while sliding the switch to the ON position. Then try uploading your program to the TinyZero and it should work. You may need to try this several times if it does not work the first time.
All batteries are sold separately
