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:
