- GND pin in the P20 5V/12V connector is not actually connected to GND
- The heartbeat LED is on...
Homely WSN Basic Board V2 is an IoT board to collect environmental data (temperature, humidity, and pressure) and to push them to a centralized server through Wi-Fi. This is the enriched successor of the Basic Board V1, that improves different aspects:
- energy efficiency (lower consumption during deep-sleep)
- onboard recharge for single-cell Lipo battery
- measurement of battery level based on...
