Диммер Создаем на базе релейного блока с симмисторным выходом https://easyeda.com/Alex_AW/Rele_4in4out_rs485_din_SMD_copy-68ff5b701321441db7af0a9c7a22ec00
Для этого в схеме заменим оптосиммисторы с встроенным датчиком нуля на симмисторы без датчика. Добавим в схему датчик перехода через 0. Изменим печатную плату силового блока. И допишем программу добавив диммерные функции.

RS-485 Breakout
BOB-10124
Description: This is a breakout board for the SP3485 RS-485 transceiver IC, which will convert a UART serial stream to RS-485. The SP3485 is a half-duplex transceiver, so it can only communicate one way at a time, but it can reach transmission speeds of up to 10Mbps. This board requires a very low amount of power and can operate from a single +3.3V DC supply.
