ESP32 Forum

Hello guys! I'm a brand new developer for esp32 and recently instated to develop an application for IoT but, in order to protect my job I decided to use only the module and intersert it I'm another module.
I have here the shield with bended wires that permits insert the module, load the program, test and take it out (see the attachment). I would like to purchase a simple shield with the same system (with bended wires)
With this resource, we could do the change of the module in an easiest way I'm the field. Could you please indicate me where to purchase it?

Thanks in advance!

Why do you think you would need to change modules that often in the first place? ESP32 supports in-system programming (via the UART) as well as OTA updates for fully hands-off programming; generally there is very little need to take modules out of the system.

Thanks! As I told you, I'm brand new and i would like to know more about the system. How does the UART is possible?!

I think it's somewhere in the datasheet, but the short and long of it is that if you connect GPIO0 to ground and reset the chip, you can program it using the UART0 TX and RX pins using a tool like esptool.py. It's how most development boards are wired. Suggest you get one of those (e.g. the ESP32-DevkitC but there are others) and/or study its schematics.
