Sorry about long delay. I need to sell one of my Pro Micros to my friend (ASAP project, even 24h waiting for original board will ruin it). I think that I still have second one, but it's disappear

so extra 40 days of waiting.
One problem solved, few next appear.
Part 3b - finishing mechanical assemblyFirst, hole to pass cables.

Next, quick check if LCD and converter still working. Beware, backlight driver (build-in) need something about 12V.

Yep, it's working. Changing language to english are simply, just need to discover pinout for keypad. Backlight driver working when applied +12V (LED sypply) and +3.3V (driver supply) for whole LCD.
Todo:
- wire laptop buttons to LVDS converter (maybe IR receiver too),
- backlight dimming.
Part 4 - WaxBee converterI not thrust SMT connectors, especially micro USB. First I decided to solder short wires between board and USB-B socket (call it printer-type USB).

But I lost half day and two 22 ohm resistors on PCB without positive effect. Looks like signal from Atmega32U4 need to past through micro-USB connector, then I can cut cable and pass signal through USB-B adapter and next cable. I will test this solution later. Today I will stay with delicate micro USB socket.

Actually WaxBee have nice place next to LVDS converter. Plywood have few gaps designed to fix USB-B board.
Wiring digitizer.

I have finished small PCB which I used to earlier tests. I should remove it, but 3.3V LDO fits here nicely.
I only use 3 wires: VCC, GND and RX because digitizer should work without any extra command.
This decision was big mistake. Digitizer can run without commands but cannot run with random commands - RX pin floating. As a result, WaxBee perfectly read X/Y position but cannot read buttons and pressure

Finding cause of the problem was rather funny. As soon as I connect RX pin to VCC, problems disappear. But later I decide to play fair and connect digitizer RX to WaxBee TX via extra 1k resistor (standard 10k resistor are build-in on digitizer board).
Wacom template.
I use standard template, Penenabled ISDV4 to Intuos2 12x18
For my digitizer, max X = 28811, max Y = 18083. Digitizer active area are bigger than LCD active area. I need to trim that, min values too, but that will be done later.
Todo:
- trim min/max for coordinates for digitizer,
- connect all parts at once and test jetter,
- clean front glass on both sides.
