Great for initially programming the bare modules before using OTA updates. Has a nice power switch too. Boot and reset switches are also fitted.

Working esp-wroom-32 programmer. ESPs fit well without any additional fiddling. Worked straight out of the box with Arduino 1.8.19 IDE with esp32 package.

ESP32 module clips in and you then have a device that is similar to the DEV Kits, great for programming device prior to fitting them to PCB.

Came with half of the pins bended. When was trying to get them strait, one come off, so that means 2 things. Or it been bended several times, or it made from bad matirials. Unfortunately did not expect my needs.Update:After resoldering damadged pins, it seems working and other problems not detected yet.

Works well, for limited number of of board ESP32 re-programing uses/Ideal to use instead of the ESP32-Prog with the current shortage of them.

wird der Programmieradapter an eine USB Schnittstelle angeschlossen und öffnet man den USB-Port auf dem Rechner geht das Gerät unmittelbar in den Programmiermodus und das laufende Programm wird angehalten. Also keine Chance das Programm mit diesem Programmieradapter über USB seriell oder mit einem JTAG Debugger zu tracen.Ich bin von einem Einzelfehler ausgegangen und habe einen 2. Adapter geordert, leider das gleiche Verhalten. Somit ist das wohl ein Serienfehler. Fazit: Unbrauchbar
