Hi all,
I normally use an 'ESP32 Dev Kit C' for my projects. This time I want to create a PCB and solder an ESP32-Wroom-32D chip direct to it. This will make my project much smaller.
So, I have bought 5 of the below:
Then, I made the below circuit as I think it is the most basic that I need to be able to upload code.
The USB TTL Interface has a built-in AMS1117 3.3v regulator in it.
Can people please tell me if the above circuit will work.
Many thanks
Alan

You need at least a power-on reset RC network on your EN pin. Given that you have an 10K pullup already, simply add an 1uF between ground and EN and that should be fixed.
