+# Pipad
+In this project, I am building a replacement logic board around a Raspberry Pi CM4.
+
+I have a [project on Hackaday.io](https://hackaday.io/project/177256-put-a-raspberry-pi-cm4-into-an-original-ipad) 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 Even browsing the web in Safari is difficult, since iOS 5 has out-of-date TLS CAs.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
