BetaFPV Matrix 1S brushless (5in1) G4 V2 flight controller

The BetaFPV Matrix 1S 5-in-1 II Brushless Flight Controller is a next-generation AIO board built for pilots who want more power, more durability, and a cleaner 1S whoop build. Based on a proven all-in-one design, it combines the flight controller, 12A ESC, OSD, ELRS 2.4GHz receiver, and 5.8GHz 400mW VTX into one compact unit. If you are building a high-performance indoor whoop or a lightweight freestyle setup, this board delivers the reliability and punch to match.

With its upgraded 12A continuous ESC, tough 3-point impact-resistant mounting, and the freedom to choose between plug-and-play or DIY installation, the Matrix 1S G4 V2 is a serious upgrade for demanding 1S brushless drones.

Why Choose the Matrix 1S G4 V2?

• 5-in-1 all-in-one design: FC, ESC, OSD, ELRS 2.4GHz RX, and 5.8GHz VTX in one board
• Upgraded 12A ESC: 12A continuous and 18A peak output for stronger 1S performance
• Built for crashes: reinforced 3-point mounting and durable 1.0mm PCB construction
• Flexible build options: available for soldered or solder-free setups
• Powerful G473 processor: smooth control response for precise flying and freestyle
• Optimized board layout: improved reliability and cleaner integration
• Integrated 400mW VTX: ideal for compact FPV builds

Important Notes

• Warranty covers manufacturing defects only. Damage caused by user error, crashes, assembly/disassembly, modifications, voltage spikes, electrical fire, or water contact is not covered.
• VTX power: Higher output increases power consumption and heat, which may reduce flight time. For indoor flying, 25–100mW is recommended.
• VTX antenna: Always connect the antenna before powering on. Alternatively, set output power to 0 to avoid damage.

Upgraded 12A ESC for More Power

The new ESC has been upgraded from 5A to 12A continuous with 18A peak, giving your 1S quad more headroom and more confidence under throttle. It also features 12 MOSFETs and gold-plated connectors for improved conductivity, efficiency, and overall power delivery.

Durability Built for Real Flying

The 3-point mounting design helps reduce damage during impacts, while the 1.0mm PCB improves structural strength for better crash resistance. This makes the Matrix 1S G4 V2 a great pick for pilots who push their whoops hard indoors or outdoors.

Two Installation Options

Choose the setup that fits your build style best:

• Solder-free version: faster installation and easier maintenance
• Solder-required version: more flexibility and lower overall weight

Built-in ELRS 2.4GHz Receiver

The integrated ELRS 2.4GHz receiver supports the CRSF protocol and can be updated to ELRS V3 without changing the FC firmware, making it a convenient and future-ready solution for modern micro FPV builds.

• Plug in and unplug 3 times
• Double flashing light = bind mode
• Solid light = connected

Bluejay ESC Firmware Support

This board supports Bluejay ESC firmware with DShot300/DShot600, RPM filtering, and selectable 24/48/96KHz frequencies for tuning your flying experience.

Important: Do not flash the ESC too often, as repeated flashing may increase the risk of damage.

Ports and Connectivity

By default, UART2 is assigned to the VTX and UART3 to the receiver. The board also allows expansion for additional accessories such as GPS, CRSF devices, and more, giving you more flexibility for custom 1S projects.
