Re: Anyone running OctoPrint on $9 chip?
Update 2:
Got the C920 running (not completely finished, but it works) and as expected the delay with WiFi is quite big, but that's enough to monitor the print remotely 😉 .
Best news is that i was able to use the microUSB C.H.I.P. port, using a MICRO-USB-OTG-ADAPTER and standard USB-A to USB-B cable, to connect to a Arduino Mega 2650 (with Marlin firmware) 😀
Knowing that i can communicate via the microUSB OTG i do not have to use the MiniRambo P3 Rx Tx pins AND i have the USB 2.0 port free to connect other things.
To power the C.H.I.P. i will now have to use its U13 GND and CHG-IN PINs because the microUSb port is not a power source anymore.
Wait, so that micro USB can be used as another host port with an OTG adapter? I've been needing a second port for a project without going to a hub...
Yes, isn't that great. I didn't find any micro USB to USB-B cable. But the OTG adapter works fine. Bought mine with some other parts from Olimex.
The only problem is to power the C.H.I.P. via the U13 40pin female header on pin 1 and pin 2. Check
