Re: DevKit Auto USB Programming: A New Fix

Great! Glad to hear it's being explored. 100% agree, as I said in my prior reply, it would only take a series resistor with the CAP to solve the problem you present. Doesn't require too much to soften the discharge. Also agree a "TEE" would work as well (in effect the same thing). One would want to ...

Re: DevKit Auto USB Programming: A New Fix

Thanks for the comments. 100% agree that this is not a perfect solution, but was meant to be easily implemented. Hopefully the Espressif folks will see the concept here, and actually fix the circuit for everyone. Really if you think about it, this solution is at least no worse than putting a cap on ...

DevKit Auto USB Programming: A New Fix

Hello Forum Folks, There have been numerous conversations about the behavior of the clever little 2-Transistor circuit used on DevKit boards to allow for Host tools to initiate bootloader and code download to ESP devices. Seemingly inexplicably it works "no problem" for some people, "never" for some...
