Does anyone know the manufacturer/part number for the tactile switches used on the ESP-PROG board?

I like the appearance and "feel" of them and would like to use on one of my own boards.

Espressif's schematic just refers to SW-4P-SMD, and there doesn't seem to be a BOM file available.

Thanks!

I have a custom board with an ESP32-S2-WROVER module. (Board and parts sourced from JLCPCB).

REPL etc. all works fine.

When I flash it with new firmware, the initial output is as follows:

esptool.py v3.2-dev
Serial port /dev/cu.usbserial-143401
Connecting....
Chip is ESP32-S2
Features: WiFi, No ...

Many ESP32 related sites refer to GPIO pins 34-39 as "input-only", for example:

https://randomnerdtutorials.com/esp32-pinout-reference-gpios/

GPIOs 34 to 39 are GPIs – input only pins. These pins don’t have internal
pull-up or pull-down resistors. They can’t be used as outputs, so use these ...

Thank you!

One more quick question: is the cable connector for the PROG interface a standard IDC connector?

e.g. https://lcsc.com/product-detail/IDC-Con ... 01936.html

Thank you!

I'm re-designing an ESP32-based board to be used with the ESP-PROG. I am getting rid of USB connector and USB-UART chip.

So, two questions:

1. Is it necessary to implement both the PROG and JTAG interfaces on the target ESP32 board, or is it ok to just support the PROG interface.

2. Should the ...
