I have a question about powering the FEZ Cerberus board without using one of the GHI power modules.
Since we want to power the FEZ Cerberus from the power-line (230V AC), I want to know if the Cerberus will work when we supply 3.3V on pin 1 and 5V on pin 2. Or is it needed to set some voltage on one of the other pins?
I am a newbie and with my little knowledge I can see that in the schematics of the USB Power DP module, PIN 7 have Vcc on it. Also, when I using a multi-meter I have found that pin 7 is 3.3 V when I have attached the USB Power DP module to an adapter.
I have found a PCB mounted power supply from MeanWell. The PM10-5 (https://www.meanwell-web.com/product-info/ac-dc-power-supply/pcb/pm-10/product/PM-10-5) seems suitable to me. Combining the GHI USB Power SP module logic and so using a LM1117-3.3 with an electro cap, the 3.3V can be substracted from the 5V in my opinion. Should it work or am I missing something?
Any help would be appreciated. Thanks in advance!
