Fx3u 24mr
This repository ships a schematic but no board layout.
Fx3u 24mr is an open source STM32 PCB design by eddyem: a 2-layer board with 234 components (97 distinct parts). It is built around the BME280, STM32F303CBT6, ISO1050DUB, 74HC4051 and more. Filed under sensors.
Code samples and ready projects based on bare-metal STM32
A usefull thing made of chineese FX3U clone ===========================================
Works over RS-232 (default: 115200, 8N1), CAN (default: 250000 baud) or MODBUS-RTU (default: 9600, 8N1).
You can see pinout table in file hardware.c.
Values in parentheses after flags command is its bit number in whole uint32t. E.g. to reset flag "frelayinverted" you can call frelayinverted=0 or flags2=0`.
