ESP32 Forum

Dear Forum Members,

I hope this message finds you well.

I have attached a schematic diagram for a project I am working on. Before proceeding further, I would appreciate it if someone could review the schematic and let me know if there are any issues or potential problems that need to be addressed.

Your feedback and suggestions would be greatly appreciated.

Thank you in advance for your assistance.

Best regards,

Salamandra

If any, remove C46. I also don't see a RC network for CHIP_PU. I'm also missing I2C pullups on the SDA/SCL lines; the internal pullups of the ESP32 don't suffice. Depending on if you're OK with it, you can delete the CP2102 and connect the USB-C connector directly to the integrated USB-JTAG-serial converter on GPIO19/20 as well.

Given that you're using a bare chip and designing in a RF trace antenna, I presume you also have the needed 8GHz VNA plus knowledge to properly tune everything?
