Description

Designed to work with Raspberry Pi and based on the SX1268 module at 433 MHz, the LoRa HAT provides two-way data transmission up to 5 km over the serial port. It supports automatic retransmission, low-power modes such as deep sleep and Wake on Radio (ideal for battery-powered applications), wireless parameter configuration, RSSI signal strength indication and the LBT function, which can be used to avoid interference. It has a 40-pin GPIO connector for Raspberry Pi, a CP2102 chip for serial debugging, a UART control port for connecting host boards such as Arduino / STM32 and 4 status LEDs: UART RXD and TXD, AUX and PWR.

The package includes: LoRa HAT, antenna and USB to micro USB cable.

Please note! The Raspberry Pi is not included.
