I spent the last week on the electronic design. I finished all the boards except the one for the Pi. All the schematics and PCBs are made on Altium Designer.
I also received all the components \o/ so now I can check a last time that all the footprints are correct.
The next step is to send the gerber files of the boards for manufacturing. I’m hesitating between 2 manufacturers : OSH Park and Seeed Studio PCB. I think I will go with OSH Park (previously Batch PCB) because they have a better quality even if they are a bit more expensive than Seeed Studio PCB.
Now I have the boards, I can continue the work on the integration of the boards into the robot and the design of the head.
