Please sign up today! The Microdot web framework is quite small, as its name would imply; it supports both standard CPython and MicroPython, so it can be used on systems ranging from internet-of-things (IoT) devices all the way

Benchmarking MicroPython

In the Q&A session following my EuroPython 2025 presentation about the Microdot web framework, a member of the audience asked me what the performance of MicroPython running on a microcontroller is. This took me a bit by surprise, because while I knew that microcontrollers are slow and underpowered devices, I really had no way to quantify this. I never questioned the supposedly low performance, because it was never a problem for me. My answer to the question was that microcontrollers cannot repl

Lua beats MicroPython for serious embedded devs

Why Lua Beats MicroPython for Serious Embedded Devs In professional embedded projects, ranging from industrial automation to medical devices and commercial IoT products, developers increasingly favor high-level, lightweight, and easy-to-use environments. While MicroPython has earned praise for rapid prototyping and field deployments on microcontrollers, its active ecosystem is largely centered around hobbyist boards. It is important to note that Python’s greatest strength, its vast library eco
