Firma 30A 2-3S Brushless Smart ESC (SPMXSE1030)

Spektrum Firma 30A Brushless Smart ESC is a compact, all-in-one electronic speed controller that blends motor power management with real-time telemetry. Built around a fast 32-bit ARM M4 processor, it communicates with other Spektrum Smart electronics, delivering data such as RPM, voltage, temperature, and battery capacity directly to a compatible radio, with no extra wires or modules. Available in a standard 30A version for 2-3S LiPo setups and a Minis variant for compact builds, it's designed for easy installation—no soldering required—and features a rugged plastic case with mounting tabs, an aluminum heatsink, and a cooling fan to keep things cool. Firmware updates are straightforward via the Smart ESC Programming Box or SmartLink USB tool, and the one-wire telemetry keeps your setup simple and fast.

On the safety side, it provides multi-point protection, including over-current, automatic LiPo low-voltage cutoff, thermal protection, and failsafe, helping protect both the ESC and the battery. It supports multiple programming options—button programming, the dedicated programming box, or the PC app—so you can tune performance at the track. The compact form factor plus easy connector compatibility makes it suitable for a wide range of RC vehicles, with a waterproof design that keeps performance in adverse conditions. A high-power BEC is adjustable to power your receiver and servos, delivering reliable, integrated telemetry in real time.
