Little FOCer Rev4 ESC Electric Speed Controller - BYOH
*Usually ships in 1-2 business days. 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 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 1xCAN 1xUART 1xBlutooth Low Energy Gyroscope On board IMU Management Interfaces USB Type-C Bluetooth Management Software VESC 6 open source project compatible The Little Focer V4 is based upon the VESC®-Project.
