ESP32 Forum

I’m working on a larger project where an ESP32-C3 will handle Bluetooth communication. I’ve exposed the USB pins, set the required bootstrap configuration, and connected the device via UART1, as shown in the image.

Is there any reason this setup wouldn’t work?

This is my first time working with an Espressif device, so I want to make sure I’m not missing something obvious. Unfortunately, using an ESP32-C3-MINI-1 isn’t an option for this design.

First of all: read through the hardware design guidelines as it also gives hints on the PCB design.

Few things I've noticed:
- You want to add a 1uF cap to VDD_SPI
- I'm missing one or two 10uF bulk caps on your 3V3
- In case you need to debug chip bringup, having U0TxD available can be really useful. Suggest you hook that up to a testpad or something.

Looks good otherwise.
