The STMicroelectronics STEVAL-PLC001V1 evaluation board targets compact programmable logic controller (PLC) applications in the factory automation domain. It features a powerful human machine interface (HMI) thanks to the 3.5 inch TFT touchscreen mounted on the PCB, which eases interaction with the tool. The board implements a galvanically isolated PLC control unit with robust digital input, digital output modules, expansion connectivity options, and interfaces. The control unit consists of a powerful 144-pin STM32F746ZGT7 MCU, which handles the industrial IOs on one side and the TouchGFX display technology on the other side, implementing the ladder logic programming code and several additional options. Isolated USART port connector
EMC pad and four-layer routing
On-board RAM and serial flash
Provision for RTC, USB
Debug LEDs and reset button
