Waveshare 24654 - SX1262 LoRaWAN Node Module Expansion Board For Raspberry Pi, With Magnetic CB Antenna, GNSS Function - SX1262 868/915M LoRaWAN/GNSS HAT Features This series of products are LoRa modules using the new generation of SX1262 RF chip, with the features of long communication distance and strong anti-interference ability. Suitable for Sub-GHz frequency band network, and is available in LF (410~510MHz) or HF (850~930MHz) frequency band versions. Combined with a LoRa gateway, it can be connected to servers such as TTN to build a LoRaWAN network. In addition to the basic LoRaWAN version, it also provides optional GNSS positioning function with GPS/BD support. Common features: Standard Raspberry Pi 40PIN GPIO header, supports Raspberry Pi series boards The new generation SX1262 has higher power efficiency and longer transmission distance than the SX1278 Suitable for Sub-GHz band, combined with the gateway, can be quickly connected to a cloud server such as TTN to build a LoRaWAN network GNSS version features: Onboard L76K module with GPS/BD support, provides accurate clock and location info for node module Onboard button cell holder, supports ML1220 rechargeable cell, for preserving ephemeris information and hot starts Onboard 4 LED indicators for module operating status Comes with online development resources and manual (example in C) Specifications LoRa parameters RF Chip SX1262 Frequency Band LF: 410 ~ 510MHzHF: 850 ~ 930MHz modulation LoRa / (G)FSK Data rate LoRa: 0.018 ~ 62.5Kbps(G)FSK: 0.6 ~ 300Kbps EMIT POWER [email protected] spreading factor SF7 ~ SF12 Operating voltage 3.3V Module current consumption emitting current: 107mA@22dBmreceiving current: 5.3mA@125KHz communication bus SPI Operating temperature 0 ~ 50℃ INTERFACE 40PIN GPIO header GNSS parameters GNSS module L76K GNSS type GPS/GLONASS/BDS/QZSS L1 BAND RECEIVER (CHANNELS) 32 Tracking ch/72 Acquisition ch A-GNSS support Receiving sensitivity(ACQUISITION, RE-ACQUISITION, TRACKING) -148dBm, -160dBm, -162dBm TTFF (TIME TO FIRST FIX)cold starts 30s, Autonomous5.5s, With AGNSS POSITION ACCURACY 2.0m CEP Speed accuracy 0.1m/s Acceleration accuracy (Max) 0.1m/s² UART rate Range: 4800~115200bpsDefault: 9600bps GNSS data update rate Max: 5HzDefault: 1Hz Includes SX1262 868/915M LoRaWAN/GNSS HAT x1 868/915M Magnetic CB antenna x1 GPS antenna x1 IPEX to SMA adapter cable ~17cm x2 Screws pack x1 2×20PIN female pinheader x1 Pinout Definition What's On Board SX1262LoRa module L76KGNSS module Power chip5V to 3.3V LDO GPS STANDY mode ON/OFFOFF: turn off STANDY and GPS works normallyON: turn on STANDY, GPS stops outputting NMEA SET buttonPress to wake up the GNSS module in sleep mode GNSS module IPEX 1 connectorL76K antenna connector LoRa module IPEX 1 connectorLoRa antenna connector Status IndicatorPWR: power indicatorRXD/TXD: UART RX/TX indicatorPPS: GPS status indicator Raspberry Pi 40PIN GPIO headerfor connecting with Raspberry Pi series boards LoRa module and GNSS module pin header Outline Dimensions Resources Wiki: www.waveshare.com/wiki/SX1262_XXXM_LoRaWAN/GNSS_HAT
