AXE033 modification

[Obby]

Hello, jumped (very) late on the picaxe bandwagon.
Years ago I tried the Basic Stamp, but expensive and not enough memory.

The AXE033 is at the moment very cheap (populated pcb without lcd module)
The connection to the lcd is standard, except for the backlight, it sits on the wrong side.
The solution is drilling two holes to extend the connector to the other side.

There are no tracks there, so safe to drill.
Next you can solder in the header socket.

Notice the Anode and Kathode pcb holes stay unconnected at this stage.

You need to solder two wires to redirect the backlight to the right position.



Now you can plugin the lcd display.
Connect the power to the privided LCD connection points on the pcb.



Do not forget to adjust the display contrast.

Add a clock chip and you have a cheap serial/I2c/clock combination.

There are many different designs of LCD/OLED PCB pinout. This method will work with the type of LCD pinout shown, however It would generally be simpler to just purchase a screen that has the backlight pins at the other end and use the PCB as it was designed.

Hello,

I have a collection of about 50 recuperated lcd displays
All lcd's with 16 pin one row connector have the backlight on pins 15 and 16, hence this modification.
