5.4 Raspberry-Pi
All connections between the board and the Raspberry-Pi are protected against 5V signals. The
I
2
C bus has FET level switches. All the other signals use resistive dividers.
The following connections of the Raspberry-Pi are used:
 5V
 3V3 ( I
2
C level converters only)
 GPIO0/2 (I
2
C SDA)
 GPIO1/3 (I
2
C SCL)
The following connections of the Raspberry-Pi are used if the programming jumpers or UART
jumpers are placed:
 GPIO14 (UART-Tx)
 GPIO15 (UART-Rx)
 GPIO8 (Reset)
 GPIO9 (MISO)
 GPIO10 (MOSI)
 GPIO11 (SCLK)
