Little FOCer Rev4 ESC Electric Speed Controller BYOH (Bring your own Heat-sink version)
- The Little FOCer without a heat sink
- 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
