NodeMCU Project Platform
The PCB serves as a project base for NodeMCU powered projects. It is powered by an HLK-PM01 module that supplies the board with 5V and then the 3.3V from the NodeMCU onboard regulator is also distributed to the breakout pins.
There are breakout pins for I2C, SPI, UART, relays, and a DHT22 sensor as well as analog input and extra power connectors for both 5V and 3.3V.
In the video below you can see me making an environment monitor for Home Assistant using the PCB and an attached DHT22 sensor.
