Ok, so I dorked the 1st Mini I tried building (a7 version). Now I'm building try # 2 (A10 Version). I have built to the stopping point midstream to test the GPS. I get nothing displayed, using either Putty or VisualGPS.
First, the LED does not work, and I am sure it is properly positioned (not backwards). I do have voltage to the board. I have full voltage (LiPo 2S) at the input to the voltage regulator and I have 3.38 volts on the output side, so I know there is power to the board, the diode is working and the voltage regulator is working.
I used my multimeter to determine what voltages are showing up at what positions on the board. I've attached a pic with the voltages annotated.
I also attached pics of the board to show the soldering joints. They all look good to me. I've made 4 Eggtimer WiFi switches, all work, so my soldering, while not world class, is serviceable.
One problem might have been not properly tinning the GPS pads before filling in the slots with solder, so I wicked it out per Chris's recommendation, re-tinned the pads (a bitch of a step) and filled in the slots. I'm fairly confident that's good now.
Still no love. Nothing pops on Putty or VisualGPS. The doc says to connect at 9600 baud, 8 bits, no stop bits. No stop bits ist verboten. Minimum is 1. Is the doc wrong?
So, ideas? Do the voltages on the annotated pic make sense or is something amiss? Did I fry the GPS module? I'm at an impasse at this point. TIA for any suggestions.
