There is on-board 3.7v 14500 battery holder, that makes you use anywhere you like. There are two IIC ports, two analog ports (A0, A1) and two digital ports (D3, D4) on this LoRa radio node.
This LoRa radio node uses the extra space left over to add an RFM9x LoRa 433 MHz or RFM95 LoRa 915 Mhz radio module. They do work quite well for small data packet transmission when you need more range than 2.4 GHz (BT, BLE, WiFi, ZigBee).
- SX1278 LoRa® based module with SPI interface.
- Packet radio with ready-to-go Arduino libraries.
- Uses the amateur or license-free ISM band: ITU "Europe" license-free ISM or ITU "American" amateur (with amateur band limitations).
- +5 to +20 dBm up to 100 mW Power Output Capability (power output selectable in software).
- ~300uA during full sleep, ~120mA peak during +20dBm transmit, ~40mA during active radio listening.
- Spot for uFL connector.
