Description

The Waveshare RP2040-LoRa-LF Development Board is a compact, integrated platform for designing long-range, low-power wireless IoT endpoints. It combines the processing capabilities of the Raspberry Pi RP2040 microcontroller with the robust Sub-1GHz RF performance of the Semtech SX1262 transceiver. The board is optimized for the 410-450MHz low-frequency band, offering superior penetration and range for applications in remote sensing, industrial telemetry, and smart agriculture where Wi-Fi or Bluetooth range is insufficient.

Engineered for developer convenience, the module features a castellated design for direct PCB integration and includes a separate USB Type-C adapter board connected via a flexible FPC cable. This allows for versatile mechanical placement while maintaining easy access to programming and serial debugging. The SX1262 chip provides industry-leading link budget with programmable output power and advanced features like preamble detection and a 256-byte packet engine, making it suitable for reliable, intermittent data transmission in LPWAN-style networks.

Key Features

  • Integrated dual-core RP2040 MCU and SX1262 LoRa transceiver on a single compact board.
  • Supports LoRa, FSK, and GFSK modulation schemes for flexible protocol design.
  • Ultra-low power consumption with configurable sleep and dormant modes for battery-powered nodes.
  • Drag-and-drop programming via USB mass storage class, compatible with mainstream RP2040 toolchains.
  • Castellated module edges enable direct soldering as a system-on-module (SOM) for product integration.
  • Onboard IPEX connector for external antenna connection, includes SMA adapter cable and 2dB whip antenna.
  • Comprehensive GPIO breakout with support for I2C, SPI, UART, PWM, and ADC interfaces.
  • Includes all necessary accessories: development board, antenna, adapter cables, and USB-C programming interface.

Applications

  • Remote environmental and agricultural sensor nodes (soil moisture, weather stations).
  • Industrial IoT (IIoT) telemetry for equipment monitoring and predictive maintenance.
  • Long-range asset tracking and logistics management in warehouses or yards.
  • Wireless sensor networks for smart city infrastructure (parking, lighting, waste).
  • Custom LPWAN gateways or mesh network endpoints for private LoRa deployments.

Frequently Asked Questions

How do I program the RP2040-LoRa board and what toolchains are supported?

You can program the board using the included USB Type-C adapter. Connect it to your computer, and it will appear as a mass storage device for drag-and-drop UF2 file flashing. It is fully compatible with the Raspberry Pi Pico SDK (C/C++), Arduino IDE (using the Arduino-Pico core), and MicroPython. For LoRa functionality, you'll need to integrate a library like RadioLib or Semtech's SX126x driver with your chosen development environment.

What is the default frequency and how can I configure the SX1262 for my region?

This LF version is configured for the 410-450MHz band, typically targeting 433MHz ISM regions. You must configure the center frequency, bandwidth, spreading factor, and coding rate via software using the SX1262 library. Ensure your chosen frequency complies with local radio regulations. The library API allows you to set these parameters during initialization before transmitting or receiving data packets.

What antenna should I use and how is it connected?

The board has an IPEX (U.FL) connector. The package includes a 2dB whip antenna tuned for 423-443MHz and an IPEX-to-SMA adapter cable. For best performance, connect the whip antenna directly to the IPEX port or use the adapter with an SMA antenna. Ensure the antenna's frequency range matches your configured operating frequency to maximize RF efficiency and range.

What is the power supply requirement and how low is the sleep current?

The board operates at 3.3V, supplied via the USB-C port or through the VCC/GND pins. The RP2040 microcontroller and SX1262 chip both support deep sleep modes. While exact sleep current depends on your firmware configuration, you can achieve microamp-level consumption by putting both chips into their lowest-power sleep states, making it suitable for battery-powered field deployments lasting months.

Package Includes

  • 1 x Waveshare RP2040-LoRa Development Board (LF Version)
  • 1 x 2dB Whip Antenna (423-443MHz, ~11cm)
  • 1 x IPEX to SMA Adapter Cable (~17cm)
  • 1 x USB Type-C Adapter Board
  • 1 x FPC Connecting Cable
