Tonight was a very rainy night in Stuttgart.

Therefore I had some spare time to add some more documentation on the Project Github Page.

While doing so I found some last minute changes on the PCB. 

For Testing and Hardware Bring Up I added some more Testpoints.


New Testpoints

- TP1 EPD VCOM
- TP2 EPD CLK
- TP3 INT RV3028
- TP4 EPD PREVGL
- TP5 EPD PREVGH
- TP6 TPL5110 DONE
- TP7 RFM DIO2
- TP8 RFM CS
- TP9 RFM DIO1
- TP10 RFM ANT
- TP11 TPL5110 SHOT
- TP12 GYRO INT2
- TP13 GYRO INT1

Even more useful are Solder Jumper points for enabling or Disabling Features

Jumper:
- JP1 = Selector for EPD Display
- JP2 = If USB Power Connected and 3.3V Programmer
- JP3 = GYRO INT Emergency CUT
- JP4 = MAINS Mode / No TPL5110 Mode
- JP5 = RV3028 INT Emergency CUT

Schematics have been updated
