Hey! Remember that epic 3D image I showed you a while back? Well, guess what? I finally got my hands on the real deal! I ordered the components and the PCB of this awesome Openthing 1 ESP-CM3 Programmer Board, and it arrived yesterday. It's the key to unlocking some serious programming power. I wasted no time and started soldering all the components onto the PCB.
Then came the big moment. I plugged it in, turned it on, and bam! ... NOTHING happened! of course I forgot to turn on the USB Port!
I turned it on and bam! ... one Green LED and some magic smoke appeared! :D
I turned it off and started checking (again) - turned out 3V3 and GND was shorted but the magic smoke came from one of the expensive components which I only ordered 2 of, the CP2102N USB to UART Chip. So I replaced it - checked everything for more shortages. Turned it on again and bam!... IT WORKED!
It got recognized by the USB! Then I throwed in the ESP-CM3 and bam! ... NOTHING HAPPENS haha.
After some investigation it turned out I messed up Tx and Rx from the ESP-CM3 SO-DIMM Connector to the CP2102N which actually have to be swapped on the way. So I patched it and bam! ... everything worked... maybe... except for the Rx and Tx LEDs!
More debugging! "yay"
This time it was the CP2102N Chip which actually needs programming to enable the TXT and RXT Pins! So I downloaded this MASSIVE 1.6GB Software-suit to simply enable this Pins.. and bam!
Finally everything worked as expected and I am very happy about it!
