Custom Carrier Board for Raspberry PI CM4 + Tuya IoT

Job ID: 37447150

Budget: $250 – $750 USD

This project is to make a Rpi CM4 based carrier board controlled by Tuya IoT & Home assistant.

A electrical circuit has been made for CM4. This schematic is 100% finished in EasyEDA by me however Im totally uncertain if my schematic or connections are correct or not.

The carrier board interfaces the following:

2x RPi Cam Module v3
1x DC motor (24V 2A) DRV8874
4x proximity sensors
1x Microphone (IS2 MEMS)
1 Amplifier + Speaker
Some press buttons
1x Micro-USB connection (I would prefer to change this to USB-C)
40 GPio pin header for testing purposes

Once it is done and the PCB assembled I wish to use the Tuya firmware and design a nice Tuya Ui (panel) for this device.

* I need someone to confirm if the schematic is fully working and no missconnections, everything is connected well to avoid faulty PCB.

* Fix all problems with the circuit

* Create a PCB board + GERBER files (preferebly in EasyEDA)

* When the PCB is completed I want you to program this in Python and make me a Youtube video of how to make a Tuya panel for the very same device. This would help me to make this Tuya panel on my Tuya account and enables me to amend changes in the future.

I will ignore copy & paste applications. I attached the schematic that needs to be revised.

Thanks
