more quality, more valuable with good service from PCBway.
The I2C Relay module is a modified relay module for the Arduino, NodeMCU, STM & etc. The new module can control relay over the I2C communication. Now user can control separately 8 relays with 2 wires. I had make double layer PCB for the this module. It receive with good quality. The PCB size is 10*10cm with blue color. I attached my PCB collection from PCBWay...

My First panel project. It is with good quality.
