LoRa Radio Node V1.0 868MHz 915MHz 433MHz RFM95 SX1276 for Arduino ATmega328P, 3.7‑12V, uFL Antenna

Product Description

LoRa Radio Node V1.0 is built around ATmega328P microcontroller and RFM95 radio module. The main ATmega328P chip runs at 8 MHz with 3.3 V logic level, pre‑flashed with Arduino Pro Mini 8 MHz 3.3 V bootloader, fully compatible with Arduino Pro Mini. It features 32 KB Flash memory and 2 KB RAM.

On‑board 3.7 V 14500 battery holder supports portable field deployment. This LoRa radio node breaks out 2 I2C ports, 2 analog channels (A0, A1) and 2 digital channels (D3, D4) via 2510‑I‑type 4‑pin and 3‑pin connectors.

Features:

‑ Power supply: 3.7 V 14500 Li‑Po battery or DC 3.7‑12 V input (VCC/GND via 2‑PIN 2510‑I connector)

‑ Dimensions: 40 mm × 60 mm

‑ ATmega328P running at 8 MHz, 3.3 V logic and power

‑ On‑board 3.3 V regulator, max output current 500 mA

‑ Hardware Serial, hardware I2C, hardware SPI supported

‑ 1 × PWM pin: D3

‑ 2 analog input channels: A0, A1

‑ General‑purpose blue LED on pin 13 for status blinking

‑ 2 mounting holes

‑ Reset button

This LoRa radio node uses spare PCB area to integrate RFM95 (SX1276‑based) LoRa radio module (868 MHz). It is not suitable for audio or video transmission, but performs excellently for small‑size data packet transmission for long‑range scenarios, compared with 2.4 GHz solutions such as Bluetooth, BLE, WiFi and ZigBee.

‑ SX1276 LoRa module with SPI interface

‑ Packet radio, ready‑to‑use Arduino libraries available

‑ Operates on license‑free ISM bands: European ISM band or American amateur ISM band (subject to local amateur‑band restrictions)

‑ Software‑selectable transmit power: +5 ~ +20 dBm (up to 100 mW)

‑ Current consumption: ~300 μA in full sleep; ~120 mA peak at +20 dBm transmit; ~40 mA in active listening mode

‑ uFL / IPEX antenna connector
