RF REAPER
RF REAPER is our custom PCB devkit, purpose-built for Bruce!
Every major feature works natively, right out of the box. Sub-GHz, NFC/RFID, IR, 2.4GHz(NRF), GPS-ready, and a microSD, all driven by a beefy ESP32-S3 (16MB Flash / 8MB PSRAM). Tons of GPIOs via the AW9523 expander plus Flipper Zero & iButton header compatibility mean you can hack, mod, and build on it endlessly. Want a specific function? Ask us with an issue, we'll check it.

✨ Why and how does it look?
Bruce stems from a keen observation within the community focused on devices like Flipper Zero. While these devices offered a glimpse into the world of offensive security, there was a palpable sense that something more could be achieved without being that overpriced, particularly with the robust and modular hardware ecosystem provided by ESP32 Devices, Lilygo and M5Stack products.

Bruce also stands on the shoulders of other great open-source firmware projects, which inspired features and code across the project:
- ESP32Marauder by @justcallmekoko — WiFi/Bluetooth offensive toolkit.
- Launcher by @bmorcelli — the multi-app launcher/bootloader for the devices.
- Evil-M5Project by @7h30th3r0n3 — WiFi attack suite for M5Stack.
- M5Stick-Nemo by @n0xa — multi-tool firmware for M5Stick devices.
Bruce builds on many free-software libraries, and parts of the RF and NFC/RFID modules are derived from other projects. See THIRD_PARTY.md for third-party attribution and copyleft-compliance details.
