A Semtech SX126X LoRa driver for Micropython and CircuitPython, ported from RadioLib.
micropySX126X is a driver library that provides Micropython and CircuitPython interfaces for Semtech SX1261, SX1262, and SX1268 LoRa transceiver chips. It enables embedded devices to perform long-range, low-power wireless communication using both LoRa and FSK modulation schemes. The library is a port and modification of the popular RadioLib project, adapted for Python-based microcontroller environments.
Embedded developers and hobbyists working with Micropython or CircuitPython on devices like WiPy, Raspberry Pi Pico, or ESP32 boards who need to integrate SX126X-based LoRa communication into their IoT or wireless projects.
Developers choose micropySX126X because it offers a complete, tested driver for SX126X chips in the Micropython/CircuitPython ecosystem, saving them from writing low-level radio control code. Its compatibility with multiple hardware platforms and comprehensive feature set makes it a reliable choice for LoRa-based applications.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Supports both LoRa and FSK modulation schemes, allowing developers to choose based on range, data rate, or power requirements as shown in the extensive begin() and beginFSK() methods.
Offers blocking and non-blocking modes with interrupt callbacks, enabling responsive embedded systems without busy-waiting, as detailed in the setBlockingCallback() method.
Provides extensive configuration options for parameters like frequency, power, bandwidth, and coding rate, mirroring the SX126X chip capabilities for precise tuning.
Tested with multiple boards including WiPy3.0, Raspberry Pi Pico, and HelTec LoRa 32 v3, ensuring reliable operation across popular Micropython and CircuitPython platforms.
The README explicitly warns to compile to .mpy or into the Micropython image to prevent memory issues, indicating potential crashes or instability on resource-constrained devices.
Requires manual SPI bus and pin configuration (e.g., clk, mosi, cs, irq) for each board, which can be error-prone and time-consuming compared to plug-and-play solutions.
Focuses solely on low-level radio control without built-in networking stacks, encryption, or error handling beyond basic CRC, forcing developers to implement these separately.
