A case for the WT32-ETH01 with a RS485 module and USB Type C trigger board for power. The top snaps into the body, no screw needed here.
Also needed:
- TTL to RS485 Converter Module, e.g. https://www.aliexpress.com/item/32853794532.html
- 5 V USB Type C Trigger board, female, e.g. https://www.aliexpress.com/item/1005005995374256.html
- jumper wire
- 6x self tapping screw M2x4, e.g. https://www.aliexpress.com/item/1005003642422063.html
- super glue
Cut the jumper wire and solder it with the power wires of the RS485 module to the trigger board. Plug the other side to the power pins of the esp board. Glue the Usb-C board into the case.
I use it to read from a modbus device with Esphome. For RS485 i use a KNX cable. I've added a Esphome yaml as example.
Edit 2024-04-15: I've added a variant for 2x Wago 221-413 for easier power distribution.
