FlipMods Ultra V3 ESP32/NRF24/CC1101 3in1 WiFi Dev Board - Marauder

In this review of the FlipMods Ultra V3 the bottom line is clear: this compact add-on is aimed at Flipper Zero users who need a single, tidy board that brings WiFi, NRF24 sniffing and Subghz capability without mounting multiple modules. The reviewer found it most appealing for security researchers and makers who want a pre-loaded Marauder setup and simple integration via the Flipper Zero GPIO, with the USB-C and micro SD slot making firmware updates and data capture straightforward.

Key Features

• 18-pin connection: Sits flat on the Flipper Zero GPIO for a low-profile, stable connection that keeps the device compact while adding multiple wireless functions.
• ESP32-WROOM-32UE with Marauder: The board ships with Marauder firmware pre-loaded so users can begin WiFi and packet collection tasks without a lengthy initial setup.
• Selectable radio: A physical switch lets the user choose either the CC1101 for Subghz work or the NRF24 for 2.4 GHz sniffing, simplifying radio selection during testing.
• Micro SD slot: On-board storage supports the Marauder application and saves captured data directly to removable media for easy transfer and analysis.
• Multiple antennas: Two 2.4 GHz antennas improve WiFi and NRF24 range while a 433 MHz antenna enables Subghz experiments without swapping hardware.
• USB-C port: A modern USB-C interface is provided for firmware uploads and updates to the ESP32, removing the need to remove the board for maintenance.

Who It's For

The FlipMods Ultra V3 is best for Flipper Zero owners who perform wireless research, field testing, or RF troubleshooting and want a single module that provides WiFi, NRF24 and Subghz radios in a space-saving package. It suits hobbyists, security students and practitioners who value quick deployment with Marauder already installed.

It is less appropriate for users who need isolated radios running concurrently (the switch selects one radio between CC1101 and NRF24) or those who require detailed manufacturer support for commercial compliance testing. If simultaneous multi-radio capture is essential, consider separate dedicated modules instead.

Pros & Cons

Pros

• All-in-one board integrates WiFi, NRF24 and Subghz into a single compact add-on for Flipper Zero.
• Pre-loaded Marauder firmware reduces setup time and gets users collecting data quickly.
• Micro SD slot and USB-C port make data logging and firmware updates convenient in the field.
• Multiple antennas improve reception and range for common 2.4 GHz and 433 MHz use cases.

Cons

• The radio selection requires a physical switch so CC1101 and NRF24 cannot be used simultaneously.
• Advanced users may want more detailed hardware documentation for custom firmware tweaks.

Our Verdict

The FlipMods Ultra V3 is a practical, well-rounded extension for Flipper Zero owners who need a ready-to-use Marauder environment with WiFi, NRF24 and Subghz options in one compact unit. It delivers strong value for researchers and hobbyists who prioritize quick setup, onboard storage and easy firmware access, though those needing simultaneous multi-radio capture should consider additional modules.

Frequently Asked Questions

Does it work out of the box with Marauder?
The board ships with Marauder firmware pre-loaded on the ESP32, so basic WiFi and capture features are available immediately after connecting to Flipper Zero.

Can CC1101 and NRF24 operate at the same time?
No, the board uses a left-side physical switch to select either CC1101 or NRF24, so only one of those two radios is active at a time.

How do you update firmware?
Firmware and updates are applied via the USB-C port on the board, which is intended for uploading new ESP32 builds or patches.
