TTGO T-SAM21 (H484) ATSAMD21 MCU Module Development Board

TTGO T-SAM21 ATSAMD21 MCU Module Development Board 

It is designed and manufactured based on Microchip ARM®Cortex®-M0+ flash memory microcontroller ATSAMD21G18A-MU,Around the concept of easy embedding and use, the product is a flat design .

The USB port is designed as an integrated type-c, and the half-hole design of common modules is reserved on both sides. Eight 2.54 pitch holes are designed on both sides, which is convenient for DIY soldering header or header extension.

The distance between the pins on both sides is compatible with the bread pitch design, which is convenient for application to breadboard experiments.
