Pi Zero2W Handheld GBA SP shell
My second attempt at a small pi handheld
Based on this project
My battery expansion STL
For the display, the GBA SP runs a small ribbon cable through a hinge.
The screen works!
The TP4056 power supply this project recommend is awful. I ended up destroying two batteries with it and switching to the tried and true Adafruit Powerboost 1000C, which allows me to charge and play at the same time.
It fits but we're not done.
The screen ran very bright and I had no way in Retropie to adjust it. I decided cut the screen's power and run a wire w/ a potentiometer instead.
The battery life wasn't great either. The largest battery I could fit in the GBA SP shell was 800mah. I modelled a new larger back plate so I could fit a 2500mah battery and a ADS1015 for battery monitoring.

All done. It runs everything from the N64 and down.
The only thing I still want to try and add is a headphone jack or bluetooth support.
