TinyZero ASK1015 Basic Kit - Processor Board

The TinyZero Basic Kit (ASK1015) from TinyCircuits is an ultra-compact processor board featuring the Atmel ATSAMD21G18A 32-bit ARM Cortex M0+ processor, identical to the one used in the Arduino Zero. Measuring just 20 x 20 mm, this board integrates USB connectivity, power management, and a battery charger in a form factor smaller than a US quarter.

This kit includes an optional Bosch BMA250 3-axis accelerometer version, enabling embedded development without increasing the footprint. The board is Arduino IDE compatible with a CDC Serial bootloader for plug-and-play operation on Windows, macOS, and Linux.
