Pull Up/Down Resistors

Postby GVSU_CEStudent » Mon Apr 09, 2018 6:17 pm

We are using an ESP32-WROOM for a school project and are wondring what the value of the pull up / pull down resistors are on the GPIO pins. If anyone could point me in the right direction that would be great! Thanks!

Resistors on silicon can vary widely in value, so you can in theory expect anything from, say, 10K to 100K. Internally, we usually assume the resistance will be about 50K, but as I said, don't depend on that specific value.
