I’m following the documentation to add the ESP-01S wifi module to my SKR Pro 1.2. I ordered the module and a USB dev board, but the dev board doesn’t have a switch on it. I started the process to erase the module but I’m not sure if it’s working - the download status is at Sync and the command window just stays at case OK.
The USB interface does show up as a COM port in Windows. Did I order the wrong USB interface and if so am I basically stuck at replacing it? Or is there some other way I can proceed with a Windows PC?
You need to ground IO0 to force the esp-01 into programming mode. I soldered a small slide switch between gnd and IO0 to do this, after that, the esp-01 should accept the flash.
I modified a similar board in a similar way, except I used a momentary contact pushbutton.
It was for a community member at the local makerspace, so I don’t have pictures nor still have the one I modified.
For eight bucks and not having to wait for China shipping, I’ll happily buy the Micro Center setup and if the switch is cheap, I’ll get a couple to learn on.
