Sentry Safe plugin pinout

Plugin by H4ckd4ddy

(Flipper) 8/GND -> Black wire (Safe)
(Flipper) 15/C1 -> Green wire (Safe)

Mousejack / NRF24 pinout

Plugin by mothball187

More info from RogueMaster and Unleashed. (Both include the plugin in their firmware releases.)

2/A7 on FZ goes to MOSI/6 on nrf24l01
3/A6 on FZ goes to MISO/7 on nrf24l01
4/A4 on FZ goes to CSN/4 on nrf24l01
5/B3 on FZ goes to SCK/5 on nrf24l01
6/B2 on FZ goes to CE/3 on nrf24l01
8/GND on FZ goes to GND/1 on nrf24l01
9/3V3 on FZ goes to VCC/2 on nrf24l01
IRQ/8 is left disconnected on nrf24l01

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)_/¯

ESP32-WROOM

NOTE: Use old_hardware.bin if flashing Marauder onto the ESP32-WROOM (thanks wyldgoat!)

ESP8266

ESP32 / ESP32-WROOM / ESP8266 Pinout to Flipper Zero

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.

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)

Some other accessories to try with Flipper (Code needed!)

HC-SR04 Ultrasonic Distance Sensor

Plugin by Sanqui: https://github.com/Sanqui/flipperzero-firmware/blob/hc_sr04/applications/hc_sr04/hc_sr04.c

HC-SR04: 1 (RX0) -> FZ: 13 or 15 (these are TX pins)
HC-SR04: 2 (TX0) -> FZ: 14 or 16 (these are RX pins)
HC-SR04: 3 (GND) -> FZ: 8 or 11 or 18 (GND)
HC-SR04: 4 (5V)  -> FZ: 1 (5V)

Switch between UART Pins 13/14 and 15/16 setting in:
Flipper -> GPIO -> USB-UART Bridge -> LEFT -> UART Pins

I've had so many asking for me to add this.
