The Little FOCer
In the fast-paced world of One Wheeled boarding and other motor-driven applications, having a reliable Electric Speed Controller (ESC) is paramount. The Little FOCer Rev3.1 ESC, a Bring Your Own Heat-sink (BYOH) version, takes the spotlight with its impressive features and recent upgrades.
Compact Design without Heat Sink: The Little FOCer Rev3.1 boasts a sleek design without a heat sink, offering a space-saving and efficient solution for one-wheel boarding enthusiasts.
Vesc-Based Firmware: Utilizing VESC-based firmware ensures compatibility and performance optimization for a seamless riding experience.
Robust Construction: With 12 Gauge wire inputs, XT60 Male connectors, and 4mm Female Bullet connectors for phase outputs, the Little FOCer Rev3.1 is engineered for durability and reliability.
Integrated IMU: Equipped with an on-board Inertial Measurement Unit (IMU), this ESC is designed for precision and stability in balance applications.
Bluetooth Connectivity: The integrated Bluetooth NRF 52840 allows for easy connectivity and remote monitoring, enhancing user experience.
DRV Less Design: Featuring a DRV-less design, the Little FOCer Rev3.1 offers improved efficiency and reliability by eliminating potential DRV (Gate Driver) issues.
Fault Detection: Enjoy peace of mind with sophisticated fault detection, including over-current, over-voltage, gate drive errors, and more.
User-Friendly Operation: The ESC is designed for convenience with an easy On/Off capability using a latching switch of your choice.
ESD Protected IO: The controller ensures Electrostatic Discharge (ESD) protection for Input/Output, enhancing overall system durability.
Optimized Layout: Capacitors and JST connectors are strategically positioned opposite the mosfets, allowing the ESC to be easily mounted to a metal plate or custom heat sink – ideal for compact installations like one-wheel boarding controller boxes.
Increased Current Limits: Enjoy higher performance with increased current limits, catering to diverse user needs.
Support for Phase Filters: The addition of phase filters enhances motor control capabilities, providing smoother operation.
