RA-02 LoRa Radio NODE V2.0 SX1278 (433MHZ), 3.7V Battery Holder with Antenna


SKU: WL-028 Categories: , Tags: , , , ,


The LoRa Radio Node v2.0 based on the ATmega328P and Ra-02 433Mhz radio module. The main chip ATmega328P clocked at 8 MHz and at 3.3V logic, which use the for Arduino pro mini 8Mhz 3.3V bootloader, usage same as the for Arduino pro mini. This chip has 32K of flash and 2K of RAM.

On board with a 3.7V 14500 battery holder, so it can use anywhere you like. In this LoRa Radio Node, we break out 2 IIC ports, 2 analog port (A0 A1) and 2 digital port (D3 D4) with 4 pin and 3 pin 2510-I type header.
