Overview

RAK4270 Breakout Board is a simple board specially designed to facilitate the external connection of RAK4270 pins. The main purpose is to access the pins of the stamp module over two (2) rows of 2.54 mm headers. Hence, it is convenient to debug the RAK4270 Breakout Board.

The RAK4270 LoRa Module includes an STM32L071 MCU and an SX1262 LoRa chip, which supports eight (8) spreading factors (SF5 ~ SF12) and signal bandwidth that can be adjusted between 7.8 kHz to 500 kHz. It has Ultra-Low Power Consumption of 2.31 μA (down to 1.61 μA @ 2.0 V) in sleep mode, but during the Transmit mode, it can reach the maximum output power of 22 dBm. As a receiver, it can achieve a sensitivity of -148 dBm.

The module complies with the LoRaWAN 1.0.2 protocol, so it can be used for implementing LoRa networks or Lora point-to-point communications. The module is suitable for various applications that require long-range data acquisition and low power consumption, like smart meters, supply chain and logistics tracking, agricultural sensors, smart cities, etc.
