NodeMCU v3 pin function change!

Chinese manufacturers did some improvement to nodeMCU v3 design.They replaced the USB / Serial chip with one that does not require an external resonator. Since this chip is “drop-in replacement” PCB did not change, resonator is just not placed in. But… it looks like GND pads of resonator were only path connecting GND plane with pin GND next to Vin pin. So…

If You want to power nodeMCU with external power supply via Vin pin, connect power to Vin and GND to some other GND pin on board, not this next to Vin.

NodeMCU V3

NodeMCU WiFi module based on ESP8266 (ESP-12E module). This board comes with factory sealed ESD bag. If you want to be sure that board is 100% ok you may buy slightly more expensive one which was flashed and tested in Nettigo.
