Detail

The FETtec 4in1 ESC 35A V1.1 is a compact 4-in-1 ESC based on the STM32G071 (64MHz), built with high-quality 40V MOSFETs and featuring active current limiting. It supports 3S-6S LiPo. The V1.1 revision adds more clearance around the battery pads, a separate blue LED for each ESC, a new protection circuit for the signal I/O lines, and moves the capacitors away from the mounting holes. It comes with proprietary FETtec firmware and supports KISS and Betaflight 4.1+ passthrough. The integrated current and voltage sensor provides serial telemetry through the TLM pad. Note: Regarding capacitor capacity, the official product page states "470µF", while the official manual recommends "minimum 330µF (337CKE050M)"; the manual was likely prepared for an earlier revision, so both values are listed. Weight information is not provided by any official source.
