Product Description
Brand new never used. For use in builds up to 84v 20s.
Little FOCer V4 ESC Electric Speed Controller
- Uses Vesc based firmware
- DC Input 12 Gauge wire to XT60 Male
- Phase Output 12 Gauge wire to 4mm Female Bullet connectors
- On board IMU for balance applications
- Integrated Bluetooth ESP32
- DRV less design
- Sophisticated fault detection for over-current, over-voltage, gate drive errors, and more
- Easy On/Off capability with latching or momentary switch of choice
- ESD Protected IO
- 72mm x 84mm PCB footprint
- ADC1 and ADC2 internally equipped with 10k Ohm pulldown resistors.
- support for phase filters
- ASS support (Advanced Sensorless Startup
New features in Rev4:
- Smart LED Control
- 5V 2A accessory power supply
- 30% Cooler operation vs the v3.x
- Off=400µA
- Momentary Pushbutton Support with Auto-shutdown
- Safety-limited 5V supplies at the On/Off and Hall connectors. Shorting these supplies will not cause brownout of the entire controller
*Note that the UART and ADC connections are now different than the typical VESC "COMM" connector
| Specification | Value |
| Nominal Input Voltage | 28V to 72V (8s to 20s Lithium Ion) |
| Recommended Lower voltage limit | 24V |
| Absolute Maximum Operating Voltage | 84V |
| Battery Current Consumption |
Off=400µA Idle< 0.8W Max (ext.) = 100A |
| Peek Phase Current | 250A |
| Peak Efficiency | 95% or greater |
| PET PWM switching frequency range | 10kHz to 60kHz (Center Aligned PWM) |
| Minimum recommended motor phase to phase inductance | 10µH |
| Supported Motor Types | BLDC and DC motors |
| Input Capacitance | 602µF |
| Operating Ambient Temperature Range | -20C to 50C |
| Storage Temperature Range | -35C to 85C |
| Thermal Cutback | The controller linearly reduces maximum output current when the internal controller temperature is above 80C. Complete cutoff at 100C, the control board over-temperature threshold |
| Communication Protocols |

| Gyroscope |
On board IMU |
| Management Interfaces |
USB Type-C Bluetooth |
| Management Software |
VESC 6 open source project compatible |
