Please use the following board/schematic and NOT the svn:
Start with the parts on page 1 and page 2 of the schematic.
Don't place the battery yet.
Use hotair gun for IC1 and U$7.
Do not place (DNP) R55 and R60.
C9 should be a 0 ohm resistor (jumper).
R26 should be changed to 110K there is a reel in the box.
IC3 is now a 500ma part. CAT6219-330TDGT3 Do not use same part as IC13.
If using micro usb, place it now. If using mini usb, wait till later as it goes on the bottom.
Once that checks out proceed to third page of schematic, and install the MCU (IC12) and the related parts.
Dont install the buttons and speaker yet, as they go on the bottom.
Now flash MCU with: L1 PM3OLED Firmware
Before installing the OLED display and battery, ensure the proxmark is properly working via USB by installing a jumper wire from F1 (PTC Fuse) to TP10 to provide 5V to the board. Plug into a computer and verify the correct USB VID/PID. This is also a good time to install required proxmark3 usb drivers and the proxmark3 application for your OS.
