This is a Raspberry Pi LoRa HAT based on SX1262, which covers the 868MHz frequency band. It allows data transmission up to 5km through the serial port. By utilizing the new generation LoRa spread spectrum modulation technology, the communication distance of the module is as long as 5km, also supports auto repeating to transmit longer. Other features include Wake on Radio, wireless config, carrier sensing, communication key, and so on. Comparing with normal LoRa modules, the SX1262 LoRa HAT achieves a longer communication distance, higher rate, lower consumption, better safety, and anti-interference. It is suitable for various applications such as industrial control, smart home, data collection, etc. What's on Board: SX1262 LoRa module 74HC125V: voltage level translator CP2102: USB TO UART converter Raspberry Pi GPIO connector: for connecting with Raspberry Pi USB TO UART port UART header: for connecting host boards like STM32/Arduino SMA antenna connector IPEX antenna connector Indicators: RXD/TXD: UART RX/TX indicator AUX: auxiliary indicator PWR: power indicator UART selection jumpers A: control the LoRa module through USB TO UART B: control the LoRa module through Raspberry Pi C: access Raspberry Pi through USB TO UART LoRa mode selection jumpers Features: Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards Onboard CP2102 USB TO UART converter, for serial debugging Brings the UART control interface, for connecting host boards like Arduino/STM32 4x LED indicators, easy to check the module status LoRa spread spectrum modulation technology, up to 81 available signal channel, longer communication distance, more robust to interference Auto multi-level repeating, suit for ultra-long-range communication, allows multi-network on the same region Low power consumption features like deep sleeping and Wake on Radio, ideal for battery-powered applications Customizable communication key which won't be retrieved greatly improves the security of user data LBT support, monitoring the signal channel noise before transmitting, greatly improves the success ratio under an extreme environment RSSI signal intensity indicating support, for evaluating signal quality, tuning the network Wireless parameter configuration, by sending wireless command/data packet, remotely configure or retrieve the module parameter Supports fixed-point transmission, broadcast, signal channel monitor Useful link: To do Hardware and Software setup, please follow this tutorial.
