Yes, but then it reads 2 more after that to validate.

This is not completely fixed yet since https://github.com/pybricks/pybricks-micropython/pull/175 didn't get merged.

From what I understand, the main problem is that the firmware for the Build Hat has to be signed and we don't have the signing key ([related code](https://github.com/RaspberryPiFoundation/python-build-hat/blob/16f50efcdaf0ba8593f2d09f369bf6539d63ada0/buildhat/serinterface.py)). There was...

We don't want to say this too loudly because we're really busy working on EV3 right now, but there has been a new development: https://www.raspberrypi.com/news/build-hat-firmware-now-fully-open-source/ So adding support for the...

We've been super-busy working on EV3 support lately. And this is lower on priority list. Hopefully some day it will get done. I did buy one of these recently, so...

The first step would be to just build the existing firmware from https://github.com/raspberrypi/buildhat just so we can start to get an understanding of how the whole process goes. Then the...

In theory, the Build HAT could be used with anything that has a UART to connect to it. One thing I am not sure about though is the reset pin....
