A LoRaWAN node based on the Arduino ProMini and the RFM95 LoRa module. Based on the original design by Doug Larue, but with some additional options:
- u.FL antenna connector
- Grove connector for I2C (can also be used for analog or digital signals)
- Circuitry to measure battery voltage
- Arduino Pro Mini 3.3V, 8 Mhz
- RFM95 module (frequency band based on your location)
- Pin headers
- Edge-mounted SMA connector (e.g. this part) or wire-antenna of correct length
- Board can be powered directly from 2 AA batteries to the 3.3V input
