❓ Frequently Asked Questions
Q: Do I need any firmware on my Flipper Zero?
A: The QUAD board works with both stock and custom firmware! For best experience, we recommend Momentum firmware. With stock Flipper firmware, you can use the board via the Marauder companion app or serial bridge with a PC serial monitor. Custom firmware (Momentum, Unleashed, Xtreme, RogueMaster) provides the easiest experience with full ESP32 integration.
Q: Can I switch between Marauder, Bruce, and Ghost ESP?
A: Absolutely! Simply connect the QUAD board to your computer via USB-C and flash your preferred firmware using the ESP flasher tool. Instructions included.
Q: Will this drain my Flipper's battery faster?
A: Yes, the QUAD board draws significant power (especially WiFi). Expect 2-4 hours of active use on Flipper's battery. We recommend an external battery pack for extended operations.
Q: Is GPS required for WiFi attacks?
A: No, GPS is optional. It's mainly used for wardriving (mapping WiFi networks with coordinates). All other features work without GPS.
Q: What MicroSD card should I use?
A: Any MicroSD card up to 32GB formatted as FAT32 works. We recommend Class 10 or higher for faster write speeds when logging packets.
Q: Can I use this for Bluetooth attacks?
A: Marauder includes Bluetooth scanning capabilities. For advanced Bluetooth attacks, consider switching to Bruce or Ghost ESP firmware which have more BLE features.
Q: How is this better than buying modules separately?
A: Cost, convenience, and integration. Buying ESP32 WiFi board ($40) + CC1101 ($40) + NRF24 ($40) + GPS ($30) separately costs $150+ and requires managing multiple boards. QUAD combines everything for $99 with better power management and integration.
Q: Does this work with Flipper Zero official firmware?
A: No, official firmware does not support external ESP32 boards. You must use community firmware (Unleashed, Xtreme, RogueMaster, etc.). These are free and easy to install.
