logic level



  • So I wanted to connect the M5Stick to the CJMCU-8118 module that has 3V3 logic and needs 3V3 for power. I am not sure if I can just use some 3V3 regulator to step down the voltage from M5Stick and connect data lines directly or if I need logic level converter for data lines. I looked at the schematic on github and it looks like the grove pins are connected directly to the mcu.



  • @smrtokvitek just use some 3V3 regulator to step down the voltage from M5Stick and connect data lines directly. As you said, the data pins all connect directly to esp32.
