MICROPYTHON SBC

TMCM-0960-MotionPy V21

Hardware Version V2.1 | Document Revision V3.00 • 2021-07-01

The TMCM-0960-MotionPy V21 board is a single board computer running MicroPython. It comes
with several communication interface options like CAN, RS485, UART, and SPI. It offers two stan-

dard PMOD connectors and separate GPIO headers. With a wide supply voltage range of +6...+36V
and industrial field bus interfaces it is the engineers’ swiss-army-knife for small automation appli-
cations.

Features

• Board supply voltage: +6V to +36V
• CAN, RS485, UART
• 2x standard SPI/PMOD interfaces and

connectors

• GPIO connectors and headers
• CAD design files available for down-

load on
