Re: ESP32-Wroover-E: looking for an I/O shield

For the ESP32-DevKitC I'm not sure if you'll find something. Designing your own and making the PCB in a low-cost PCB manufacturer is sometimes a big deal. It is what I have done: I have designed my own PCB..; If your are interested by the Gerber files, just ask ! For the ESP32-DevKitC I'm not sure ...

Re: Reset: is a 10K resistor required ?

you can keep it low during flashing
Do I can or do I must: I mean is a temporary pull down to GND is enough to start the flashing process of the firmware a few seconds later ?

All the articles that I have read shows a I00 permanently to GND all along the flashing process....


Thank you,

Re: Reset: is a 10K resistor required ?

because a floating pin is subject to electrical noise which could cause random resets It is exactly what I meant, and I supposed that when RESET is engaged, the value of R is so high (10K) that there is no risk of short circuit: I=U/R = 5/10000 = 0.5mA By the way, do I have to maintain RESET engage...

[solved] Reset: is a 10K resistor required ?

Hi, I use an ESP32 Pinboard and on this page: https://www.14core.com/wiring-and-flashing-programming-esp-32-esp32s-with-usb-ttl-uart/ it is shown that there is a 10K resistor between the +3.3V power supply and the RESET button. The RESET button can be soldered on the pinboard, but this 10K is not pr...
