+## Raspberry Pi Zero : Prerequisite
+
+Mount you'r SD Card to you'r computer and add the following line a the end of ```/boot/config.txt``` file.
+
+```
+enable_uart=1
+```
+
+Additionally you can look at the baudrate in the ```/boot/cmdline.txt``` file, which should be ```115200``` by default.

+## Raspberry Pi Zero : Pinout to Flipper Zero
+
+```
+PiZero: 4 (5V) -> FZ: 1 (5V)
+PiZero: 6 (GND) -> FZ: 11 (GND)
+PiZero: 8 (UART0_TXD) -> FZ: 14 (RX)
+PiZero: 10 (UART0_RXD) -> FZ: 13 (TX)
+```
