Re: Setting the voltage on the Mini-360 regulator
|
Pins 8-10 should all be +5V, while 3-6 are GND. Pins 1 and 2 should be +12V with respect to GND. The fact that you do not see 12V on pin 2(+) and 4(-) makes me wonder about the external power supply. What does it read? I don't know what you're doing when you say: When I moved the 12V+ to one of the 12V (white pins at the far end of the header the voltage showed up and I was able to get the regulator at exactly 5V on the money..

Sent: Wednesday, April 20, 2016 3:33 PM Subject: [SoftwareControlledHamRadio] Setting the voltage on the Mini-360 regulator I have a dilemma, I followed the instructions for setting the regulator, however the connection points called out J1, pins 2 & 4 for the 12V+ did nothing. I had the 12V ground to one of the G's. I connected the DMM to the 5V+ and G to pick up the voltage output from the regulator but got nothing. When I moved the 12V+ to one of the 12V (white pins at the far end of the header the voltage showed up and I was able to get the regulator at exactly 5V on the money.. Question... Why didn't the 12V+ work through pins 2 & 4? I checked the solder points and they are good. What would explain this and if pins 2 & 4 didn't work for setting the regulator what adverse affect will that have after I seat the modules? Steve NS3L
