There are rumors of a cheap chip that does USB natively, has an Open Source toolchain, and costs a quarter. These aren’t rumors: you can buy the CH552 microcontroller right now. Surprisingly,… ...

Now you can buy the microcontroller itself as a standalone product for just $1. You can find a list of places to buy one (or a bunch) at Raspberry Pi’s RP2040 website .

We’re in an exciting time for cheap microcontrollers, as with both the rise of RISC-V and the split between ARM and its Chinese subsidiary, a heap of super-cheap and very capable parts are co… ...

Meet the Raspberry Pi Pico 2 W, a tiny board designed around a microcontroller that lets you build hardware projects at scale. Raspberry Pi is once again using the RP2350, its own, well-documented ...

Microcontrollers tend to be cheap, small, and very power efficient. As you can see in the picture above, the Pico 2 W has dozens of input and output pins on the sides (the small yellow holes all ...
