RAK4270 Breakout Board is a simple board specially designed to facilitate the external connection of RAK4270 pins. It accesses the pins of the stamp module over two (2) rows of 2.54 mm headers. You can conveniently use this feature to debug the RAK4270 module!
The RAK4270 module pre-soldered to the breakout board uses 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.
You can enjoy an ultra-low power consumption of 1.5uA in Sleep mode. During the transmission mode, experience a maximum output power of 22 dBm. As a receiver, it can let you achieve a sensitivity of -138 dBm.
