ESP32-C3-WROOM-02 and ESP-PROG Custom Board

[dgduncan]

Hello,
This may be a bit of a novice question, but I am a bit confused about how to put a 6-pin ESP-PROG header on a custom board. Is it ok to simply run the 3.3v VDD pin directly to the ESP32-C3 VIN pin with a few smoothing capacitors?

Also is it recommended to add anything to the TX/RX pins? I have seen some schematics for other boards that either contain resistors or diodes? Thank you!

Yes, you can run the 3v3 directly to power the Wroom, and there's no need for resistors on the tx/rx lines. Note that you can also skip the esp-prog by connecting an USB cable directly to GPIO18/GPIO19; the ESP32C3 has an internal USB-serial-JTAG device.
