This LoRa Radio Node v1.0 is based on the ATmega328P and RFM95 915 Mhz radio module. The main chip ATmega328P clocks at 8 MHz and at 3.3V logic, and uses the Arduino pro mini 8Mhz 3.3V bootloader, which can be used like an Arduino pro mini. This chip has 32K of flash and 2K of RAM. On board with a 3.7Vdc 14500 battery holder, it can be used anywhere you like. In this LoRa Radio Node, we break out 2 i2c ports, 2 analog ports (A0 A1), and 2 digital ports (D3 D4) with 4-pin and 3-pin shell kk type connectors. These radios are not good for transmitting audio or video, but they do work quite well for small data packet transmission when you need more range than 2.4 GHz (BT, BLE, WiFi, ZigBee). Features: Power supply: 3.7V 14500 Lipo battery Operating Frequency: 915 MHz ATmega328P 8MHz with 3.3V logic/power 3.3V regulator with 500mA peak current output Hardware Serial, hardware I2C, hardware SPI support 1 x PWM pins: D3 2 x analog inputs: A0 A1 Pin #13 BLUE LED for general-purpose blinking 2 mounting holes Size: 40mm x 60mm Reset button Package Includes: 1 x LoRa + ATmega328P Board with 14500 Battery Holder 1 x LoRa 915MHz Antenna
