Pipad

In this project, I am building a replacement logic board around a Raspberry Pi CM4.

I have a project on Hackaday.io and this is the corresponding Github repository.

NOTE: Newest development takes place in cm4 branch

The Mission

The 2010 iPad is completely unsupported, and is almost useless. It will still run old apps, but almost all internet-connected apps are broken. Even browsing the web in Safari is difficult, since iOS 5 has out-of-date TLS CAs.

But still, it's a pretty good piece of hardware in many ways. If we were to replace the logic board, we could still use these parts:

• Case
• 25 watt-hour battery
• capacitive touchscreen digitizer
• 1024x768 LCD
• 2x wifi/bluetooth antennas
• mono speaker
• TRRS port
• microphone
• ambient light sensor
• four buttons (lock/unlock, volume up, volume down), one switch (rotation)
• The wifi/BT module
• 30-pin connector
