Waveshare SX1262 LoRa HAT para Raspberry Pi, modulación de espectro extendido, banda de frecuencia de 868 MHz

DESCRIPTION

SX1262 LoRa HAT for Raspberry Pi, Spread Spectrum Modulation, 868MHz Frequency Band

Overview

This is a Raspberry Pi LoRa HAT based on SX1262, covers 868MHz frequency band. It allows data transmission up to 5km through 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 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.

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

• Supports LBT, monitoring the signal channel noise before transmitting, greatly improves the success ratio under extreme environment

• Supports RSSI signal intensity indicating, for evaluating signal quality, tuning the network

• Supports wireless parameter configuration, by sending wireless command/data packet, remotely configure or retrieve the module parameter

• Supports fixed-point transmission, broadcast, signal channel monitor

• Comes with development resources and manual (examples for Raspberry Pi/STM32)
