Find MicroPython and CircuitPython Developer Leads on GitHub

Who Are MicroPython and CircuitPython Developers?

MicroPython and CircuitPython developers write firmware for microcontrollers — ESP32, RP2040, STM32, nRF52, and similar chips — using Python-like syntax instead of C or C++. They are embedded systems engineers, IoT product builders, maker-community contributors, and hardware startup founders.

For companies selling IoT platforms, embedded toolchains, cloud connectivity SDKs, OTA update services, device management platforms, or developer hardware, these are high-intent prospects. When a firmware developer stars a repo tagged micropython, contributes a driver library, or mentions keywords like "ble", "sensor", "mqtt" in GitHub issues, that is a measurable buying signal.

What GitHub Signals Do MicroPython Developers Leave?

• Starring repos: micropython/micropython, adafruit/circuitpython, adafruit/Adafruit_CircuitPython_Bundle, micropython/micropython-lib
• Opening issues/PRs mentioning: "uart", "i2c", "spi", "ble", "wifi", "mqtt", "asyncio", "machine.Pin", "busio", "displayio"
• Committing driver libraries for sensors (BME280, AHT20, SCD40) or wireless modules
• Discussions referencing ESP32, RP2040, Pico W, STEMMA QT, Feather, Circuit Playground
• Starring repos tagged: micropython, circuitpython, embedded-python, rp2040, esp32

How GitLeads Captures These Signals

GitLeads monitors GitHub in real time for two signal types:

1. Stargazer signals — new stars on repos you track (e.g., micropython/micropython, adafruit/circuitpython, your own product repo)
2. Keyword signals — GitHub Issues, PRs, Discussions, and commit messages matching keywords you configure (e.g., "circuitpython driver", "micropython uart", "ble sensor firmware")

For each signal, GitLeads enriches the developer profile: name, email (if public), GitHub username, bio, company, location, follower count, top languages, and the signal context (what they starred or said). This data is then pushed into your sales stack automatically.
