This short write up will detail my findings on replacing the EXT port with a micro usb port and a battery replacement.Replacing EXT with micro usb
I am planning on making this micro usb port fully functional with data transfer. I anticipate that the charge points will be easily located with a multimeter.
The data points will be a little bit harder.
Here are the tools you will need
- Soldering Iron and solder
- Wires. 5 colours
- Micro USB breakout board
Will be using some black coloured sugru to make everything look nice by closing any gapsBattery mod
Will require the removing of bits of plastics on the back case/shell
Will require de-soldering of the faux-GBA cart connector
Will require removing some bits of plastics on the faux GBA cart (this is to preserve the exterior look however this means you will not be able to remove & insert the faux-GBA cart any more)
Will require soldering of the board of the faux-GBA cart directly onto the main board
The battery I have located will fit with some space allowance leftover.
Search for 323896 polymer battery on your commerce platform of choice. This is a ~1800mah battery. Might be possible to fit in a larger battery but I do not have accurate measurements yet hence this battery is the only battery that I can say with 99% certainty will fit.
