STM32F030F4 2-Relay Board #39

Closed sebstud closed 3 years ago

sebstud commented 3 years ago

Hi, great project! Will it be possible to implement eForth modbus RTU for very cheep relay board based on STM32F030F4 like this: https://www.aliexpress.com/item/4000817530793.html?spm=a2g0o.cart.0.0.37833c00zITqOg&mp=1 With the stm8 I can find only the bigger version 4-relay, which is complicate to place in the small box. I don't no why there are only 4-relay with stm8 chip.
Please help me to find out the solution.

@sebstud the STM32F030F4 is certainly a µC with very good price/feature ratio but I have no plans to support anything else but the STM8 family in the near future.

What might work for you is assembling a node using standard boards: a blue STM8S103 board, a single or twin relay board and a RS485 transceiver.
