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 Embe...

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 pins onl...

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 targe...
