JTAG Debugger that fits most ESP32 Projects

[STBESP32]

Hi !

I was sold out but I rebuild another batch. They are still available.

Altera USB Blaster cheap clones e.g.: https://bit.ly/2UfJLTx can be also used for the ESP32 with moderate success. Check out this post.

I'm curious though - what do you consider "too expensive"? I have a C232HM that works well with the ESP32, and they are US$26 (ex. shipping) each

This cable has no level shifting but you are right in principle it works but not as reliable as a debug adapter with level shifting to the used ESP32 supply voltage. As I'm often work with low power/low voltage applications it was not the best fit for me.

Fair enough. There's a 3.3V version, and the 5V version works with 3.3V signals (doesn't drive at 5V).
