What is ESP32 Marauder - Double Barrel 5G?

In early 2025, we released the first version of the Double Barrel 5G featuring the BW16 / RTL8720DN chipset. It was the first complete and user-friendly package for Flipper Zero designed to work with 5G Wi-Fi.

In September 2025, we transitioned the Double Barrel 5G to the ESP32-C5 chipset due to its broader compatibility and better support with Marauder firmware. As of December 2025, most Double Barrel 5G units are based on the ESP32-C5 chipset.

The Double Barrel 5G includes two independent Marauder systems. The first is a standalone Marauder kit that can operate without Flipper Zero. The second system, based on the ESP32-C5, is controlled by Flipper Zero and is capable of handling 5G Wi-Fi operations. In addition, the unit also features onboard GPS and Sub-GHz support.

ESP32 Marauder is a linear system/firmware that can perform only one task at a time. This limitation is the core reason behind the Double Barrel design. By running two Marauder systems simultaneously, one can deauth a network with one Marauder while performing a different task with the second Marauder.

For more technical details, please refer to the comparison chart in the listing photos and the individual user manuals.
