LayerOne 2014 Badge Build

Notes

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).

R43 should be changed to 110K~120K, ask M for that part.

Jumper JP2 like so:

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.

To test main 3v3 rail, inject 5v in to 5V line at TP10. Once that checks out proceed to third page of schematic, and install MCU (IC12) and the related parts.

Dont install the buttons and speaker yet, as they go on the bottom.

Short the two pins of IC7 with a zero ohm resistor like so:

Now flash MCU with: L1 PM3OLED Firmware

Once again inject 5V in to TP10, test all the other voltages.
Test point values:
TP18 - 3v3
TP19 - 2v5
TP20 - 1v2
