One thing to be noted: power supply ?
08/22/2016 at 09:17 • 0 commentsI received a question regarding "power supply" of ULTRA. Actually this point should be noted before. Thanks.
(Case: USB cable connected)
ATMega1284P in ULTRA is working at 3.3V by FTDI embedded 3.3V voltage regulator
(Case: USB de-touched)
We should apply 3.3V between VC/GN terminal on ULTRA
Anyway, ULTRA is 3.3V system. Have fun!
