1. BLHeli_S ESC with Hardware generated PWM synchronous to MCU yields ultra-quiet motor performance.
2. Utilizes high-performance EFM8BB2 50MHz MCU
3. Lightweight: 4.2g = without heatsink & without wires / 5.6g = with heatsink & without wires / 14g = with heatsink and with all wires.
4. Footprint: 32.6*18.0*6.5 (mm)
5. Only supports Damped Light (Active Braking is the only option for BLHeli_S)
6. FW upgradable via signal wire (BLHeli_S HEX needed)
7. Anti-counterfeit code of authenticity.
8. Dynamic voltage range - Supports 2S up to 4S Input Voltage.
9. Supports Motors with super high KV (EFM8BusyBee 50MHz can handle up to 500k eRPM).
