Nanjing FarDriver Mini S12 Ultra-Compact Programmable FOC Sine Wave DC Motor Controller –

 72V Nominal Voltage (80A High Operating Current) IP67 Waterproof Small-Footprint E-Bike Controller Complete with Plug-and-Play Wireless Bluetooth Module for Electric Bicycles, Scooters & Compact EV Upgrades

Upgrade your electric bicycle or compact scooter with high-efficiency sine wave performance using the Nanjing FarDriver Mini S12 Programmable DC Motor Controller. Engineered as one of the smallest high-current controllers on the market, the Mini S12 delivers an impressive 80A working current from an ultra-lightweight frame weighing just 0.5 kg (1.1 lbs) with compact dimensions ($150 \times 150 \times 100\text{ mm}$).

Utilizing advanced Field-Oriented Control (FOC) sine wave technology, the Mini S12 provides whisper-quiet motor operation, silky-smooth throttle modulation, and high torque efficiency without adding heavy bulk to your frame. Built with an IP67 waterproof rating, it is fully protected against heavy rain, mud, and road splash. Every unit includes a plug-and-play Bluetooth Adapter for wireless parameter tuning directly from your iOS or Android smartphone.

⚠️ System Operating Limits & Compatibility

IMPORTANT VOLTAGE & SIZE SPECIFICATIONS:

• Nominal Voltage Rating: Built for 72V DC nominal battery systems (supports up to an 84V DC maximum charge cutoff).

• Current Capacity: Delivers up to 80A working current for continuous acceleration and hill climbing power in tight frame spaces.

• Ultra-Compact Footprint: Measures $150 \times 150 \times 100\text{ mm}$ and weighs only 0.5 kg, making it easy to tuck inside frame bays, battery enclosures, or under-seat compartments.

• IP67 Ingress Protection: Fully sealed casing protects internal driver circuits from dirt, dust, and water immersion.

🚀 Key High-Performance Features

• Ultra-Small & Lightweight (0.5 kg): Saves crucial space and cuts unnecessary weight on lightweight e-bikes, folding commuters, and compact scooters.

• High-Power Current Output (80A): Delivers big-controller performance in a mini-sized housing, sustaining solid torque for hub and mid-drive motors.

• Included Bluetooth Programming Dongle: Connect wirelessly using the FarDriver App (iOS/Android) to adjust phase current, set speed limits, fine-tune throttle curves, and configure regen braking.

• FOC Sine Wave Efficiency: Runs quietly and efficiently while keeping internal heat generation low compared to noisy square-wave controllers.

• Rugged IP67 Sealed Housing: Engineered to handle wet weather, off-road splash, and daily outdoor commuting conditions.

• Self-Learning Calibration Routine: Simplifies initial commissioning by automatically detecting Hall sensor timing and motor phase angles.
