The MCU used on the MC HCK already contains a 3.3V linear regulator that allows operating from the 5V that are provided by USB. But not every MC HCK will always be connected to USB – we have several power supply options...

For the upcoming shipment of the prototype kits, I will have to flash the USB bootloader to all 250 bare microcontroller chips. Even though we have a detailed description on how bootstrap the bootloader, I rather have people be able...

I am happy to announce that we have a self-hosted toolchain: The MC HCK can now act as SWD debug adapter for other MC HCKs, without requiring any other external debug adapters or development boards. The SWD interface is a debug...

From the beginning, the MC HCK was conceived to be not only cheap to produce and sell, but it was also conceived to be buildable at home, at a low cost. In this post, we’ll show how to build a...

Given that we are still waiting for components for the prototype kit, I used the opportunity to do another design iteration. The new design features (hopefully) improved analog noise performance, and a rearranged pin layout that allows to use the...

This text is an adapted version of what has been mailed to the prototype supporters. Thanks to all supporters for ordering a MC HCK prototype kit and supporting the project! The funding has been successful: almost all kits have been...

Everything is progressing smoothly with the prototypes! We’ve sold 40 prototype kits so far, which means that this undertaking will really happen. Today, the first parts for the kits arrived: DigiKey already shipped all parts that are not on backorder....

We are happy to be able to announce the first prototype MC HCK dev kits. These prototype kits are meant for early adopters, who would like to evaluate and verify the electrical design of the MC HCK, and those who...
