BetaFPV Matrix 1S 5IN1 II Analog AIO FC with ELRS & 400mW VTX

The BetaFPV Matrix 1S 5IN1 II puts the flight controller, a 12A ESC, OSD, a serial ELRS 2.4GHz receiver and a 400mW 5.8GHz analog VTX on one 26 × 26 mm board. It is the core for 1S brushless whoop and micro builds that need strong motor current and crash durability.

Key features

• STM32G473 processor running Betaflight, with 16MB of blackbox flash

• ESC rated 12A continuous and 18A peak, on Bluejay firmware with DShot300/600

• Serial ELRS 2.4GHz receiver wired to UART3 over the CRSF protocol

• 48-channel 5.8GHz VTX switchable between 25, 100, 200 and 400mW, plus pit mode

• Three-point mounting and a 1.0 mm PCB to survive crashes; larger solder pads for easier wiring

• BT2.0 battery connector and JST 1.25 motor plugs

Fit the VTX antenna before powering up, or set VTX power to 0, to avoid burning out the transmitter. For indoor flying, 25–100mW keeps heat down and stretches flight time.
