Hi,
I have see schematic from Github link you attached.
I can finish it in 3-4 days. I will use EAGLE for this project.
It can be faster, we just have to maintain our communication.
I have designed PCB since 2012 and has finished a lot of PCB for hobbyst, Industrial, Robotic, IoT, and military application. I know both firmware and hardware issue too. and I always following design guide provided from vendor to make sure my board work propperly.
Lets discuss this over messenger. Let me know the detail.
Best Regards,
Rijal
