MicroPython SBC for Test, Dev, and Lab Automation

TMCM-0960-MotionPy

Document Revision V1.00 • 2020-10-23

The TMCM-0960-MotionPy board is a single board computer running MicroPython. It comes with

several communication interface options like CAN, RS485, UART, and separate GPIO headers. With

a wide supply voltage range of +6...+50V and industrial Fieldbus interfaces it is the engineers' swiss-

army-knife for small automation applications.

CAN bus signal (inverting) Table 2: TMCM-0960-MotionPy Power supply and Communication Interface connector pin assignment Always keep the power supply voltage below the upper limit of 50V! Oth- erwise the driver electronics will be seriously damaged. Especially, when the selected operating voltage is near the upper limit a regulated power supply is highly recommended.

6 / 11 2.2 GPIO Connectors The TMCM-0960-MotionPy oﬀers three separated input/output headers, directly connected to the MCU (STM32F405RGT6). On the left side of the board, from 2x5pin header (green) - direct SPI and serial interfaces, plus three GPIO options. On the right side of the board, from two 1x4pin headers (pink / red) - MCU direct reset and boot, plus software-set digital input/output and clock signals.
