I am developing a prototype for my home automation product and need help with reverse engineering an existing PCB that I want to replicate.
The PCB is a simple Relay Controller. It has an onboard Microcontroller (PIC/Atmel) that controls 12 onboard Sugar Cube Relays (5VDC / 230VAC@5A) using its GPIOs and Relay Drivers (ULNxxx). The PCB has a female berg-strip provision to mount an ESP-12E NodeMCU. The NodeMCU and the onboard Microcontroller are connected for UART communication (RX-TX, TX-RX). The NodeMCU sends commands to the Microcontroller instructing which Relays should be switched on and off (Commands list will be provided). The PCB is powered by a Hi-link HLK-PM05 supply module.
Photographs of existing PCB and a block diagram of the required PCB will be provided to the Freelancer.
The project is urgent and we require Microcontroller firmware code + basic guide on how to program it, Schematics, Layout and Gerber files for manufacturing the PCB.
