Hello EEVblog
I have been working quite a while on a Raspberry Pi hat for robotics as an hobby, I discovered this blog while searching for information and I thought I'd share here the progress.
After trying lots of boards, I decided to focus on the Raspberry Pi for the compute because of power consumption and software available, I'm developing an hat to integrate all the electronics needed for a robot on a single board. Specs:
- XT60 Power connector
- 5V3A regulator channel for the Rasperry Pi
- Servomotors with a dedicated 5V3A regulator channel
- ATMega 4809 microcontroller
- Three channel voltage and current monitor
- Screen
- Communication Bus (right now RS485, but I'm evaluating CAN)
I release all relevant code and gerber open source, here the github repository:
github.com/OrsoEric/OrangeHat (http://github.com/OrsoEric/OrangeHat)
OrangeHat assembled and powered as of 2022-01

Impressed project! looking forward updates! how about to use a small oled display instead of the big lcd?

Along with Maze solver, what are the common robots that we can make with this hat?
