# Documenting adventures with the GPIO...
Official [GPIO layout](https://miro.com/app/board/uXjVO_LaYYI=/) created by [Aleksandr Kutuzov](https://discord.com/channels/740930220399525928/765282833744265246/993107060172542012). Official documentation [is here](https://docs.flipperzero.one/gpio-and-modules)!

(Flipper) 15/C1 -> Green wire (Safe)
# NRF24L01+ / Mousejack pinout - 8-pin
Plugin by [mothball187](https://github.com/mothball187/flipperzero-nrf24) | Affected devices from [Bastille research](https://www.bastille.net/research/vulnerabilities/mousejack/affected-devices)
More info from [RogueMaster](https://github.com/RogueMaster/flipperzero-firmware-wPlugins/tree/unleashed/applications/mousejacker) and [Unleashed](https://github.com/Eng1n33r/flipperzero-firmware/blob/dev/documentation/NRF24.md). (Both include the plugin in their firmware releases.)
2/A7 on FZ goes to MOSI/6 on NRF24
3/A6 on FZ goes to MISO/7 on NRF24
4/A4 on FZ goes to CSN/4 on NRF24
5/B3 on FZ goes to SCK/5 on NRF24
6/B2 on FZ goes to CE/3 on NRF24
8/GND on FZ goes to GND/1 on NRF24
9/3V3 on FZ goes to VCC/2 on NRF24
IRQ/8 is left disconnected on NRF24
If the nRF model is acting a bit flakey, try adding a capacitor to the vcc/gnd lines! I've not tried the Plus model so it may have a bigger need for a cap. Otherwise, I haven't had any major issues. Anything from a 3.3 uF to 10 uF should do. (Watch your positive/negative placement! Negative to ground.) I learned if you wanna get fancy, include a 0.1 uF cap in parallel. The 3.3 uF to 10 uF will respond to slow freq changes while the 0.1 uF will respond to the high freq switching spikes that the larger one cannot. That said, a single 10 uF will likely suffice for the Mousejack attack. ¯\\\_(ツ)_/¯

# Raspberry Pi Zero UART
## Raspberry Pi Zero : Prerequisite
Mount your SD Card to your computer and add the following line at 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.
