WaveShare SX1262 LoRa HAT 915MHz 2 in 1 accessory

SKU CH-FHBJ-WN2CV

Adds 915 MHz LoRa wireless up to 5 km range with 81 channels, auto repeating, and CP2102 USB-UART for Raspberry Pi, Arduino, and STM32

  • Long-range communication up to 5km with 915MHz SX1262 LoRa module
  • Lower power consumption and better anti-interference using SX1262/SX1268 chipset
  • Auto repeating extends distance and allows 81 channels for multi-network IoT
  • Secure transmission with customizable keys, RSSI monitoring, and Listen-Before-Talk
  • Direct 40-pin GPIO fit for Raspberry Pi plus CP2102 USB-UART for Arduino/STM32 debugging

915MHz LoRa HAT for Raspberry Pi

This expansion board adds long-range LoRa wireless connectivity to Raspberry Pi single-board computers via the 40-pin GPIO header. It targets developers and hobbyists building low-power IoT sensors, remote telemetry nodes or campus-scale mesh networks that must operate beyond Wi-Fi range.

40-pin GPIO and UART integration

The HAT plugs directly onto the Raspberry Pi GPIO header and also exposes a UART interface with an on-board CP2102 USB-to-UART converter for serial debugging. This dual connectivity lets the same module serve Arduino or STM32 hosts without redesigning the carrier board.

Check 915MHz band and pin clearance

Verify that 915MHz ISM-band operation is permitted in your region and that your Raspberry Pi enclosure allows access to the 40-pin header. Projects requiring other frequency bands or a different pin-out will need an alternative module.

Questions about this item

What frequency band does the SX1262 LoRa HAT operate on?

The HAT operates on the 915MHz frequency band, which is the standard ISM allocation for North America and provides up to 5km range in open environments.

Which GPIO header does the board connect to on a Raspberry Pi?

The expansion board connects directly to the 40PIN GPIO header on any Raspberry Pi model that exposes the standard 40-pin layout.

How do you switch between Raspberry Pi and external MCU control?

Use the onboard CP2102 USB-to-UART converter for serial debugging with a PC, or connect an Arduino or STM32 to the UART interface for host control; the board does not require soldering to change modes.
