I am looking for a tablet that I can hack for some home control applications. In particular this device looks like a good candidate as it is about the same cost as a WiFi thermostat and far more capable.
So 2 basic questions... 1: Are there any underutilized GPIO pins that were broken out of the CPU BGA that I can access with a fine tipped solering iron? This is commonly done so that in circuit board tests can validate that there are no solder bridges.
2. Does anyone have a I2C map to know which addresses are utilized, and as an extension to this, know how to make requests on that I2C buss.
I am sorry I know these are very broad questions. I am looking to turn this into a total home control panel including thermostat. So basically for this task I am trying to get GPIO (Preferably 3.3 or 5V) that I can use for some fets to control HVAC, and some I2C lines that I can use to dead-bug in humidity, temp, pressure, ambient light sensors, and IR motion sensor.
I will post a writeup complete with wiring and code if this works out.
