Matek FCHUB-12S V2 PDB (440A Burst)

The Matek FCHUB-12S V2 is a power distribution board for high-voltage FPV and X-Class builds, accepting 3–12S LiPo input and routing it to four ESC pads with an onboard current sensor for accurate battery telemetry.

Key features

• Four ESC power/signal/telemetry pads rated 70A continuous, 110A burst each — enough headroom for heavy-lift and X-Class motor combinations
• Built-in 440A current sensor (3.3V ADC, scale 75) feeds accurate current draw data to the flight controller
• Switchable 12V output (2A) for a VTX or LEDs, alongside fixed 5V and 12V BEC rails
• 3.3V linear BEC rail for low-current sensors and peripherals
• JST-SH 8-pin connector carries voltage, current, telemetry and all four ESC signal lines to the flight controller on one plug
