MATEKSYS FCHUB-12S V2 PDB, 8–60V DC for 3–12S FPV, 5V/12V BECs, 440A sensor, 4×70A continuous, 4×110A burst

Overview

The MATEKSYS FCHUB-12S V2 is a power distribution board (PDB) designed for 3–12S FPV drones and XClass quads. It supports 8–60V DC input and provides regulated 5V and 12V rails, a 3.3V LDO, integrated high-precision current sensing up to 440A, and comprehensive ESC connectivity. The board uses 30.5 × 30.5mm mounting (Φ3mm holes) and measures 50 × 55 × 6mm, 21g, with dual LED indicators for 5V and 12V outputs and a switchable 12V rail via PINIO.
