Little FOCer Rev3.1 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 NRF 52840 
  • DRV less design
  • Sophisticated fault detection for over-current, over-voltage, gate drive errors, and more
  • Easy On/Off capability with latching switch of choice
  • ESD Protected IO
  • 72mm x 84mm PCB footprint
  • ADC1 and ADC2 internally equipped with 10k Ohm pulldown resistors. 

The capacitors and JST connectors' are mounted on the opposite sides of the mosfets so that the motor controller can be mounted to a metal plate or other custom heat sink solution.  This is typically the best option for fitting inside the controller box of a balance board.

New features in  Rev3:

  • Increase current limits
  • support for phase filters
  • ASS support (Advanced Sensorless Startup)

FAQs

Though we are working hard to make this as easy as possible with no soldering and programming needed this is ultimately still a DIY solution.

The choice in parts and settings are still up to the user to decide. This allows for great creativity but does require some knowledge. If you are new, please research existing builds and settings before proceeding!

The Little FOCer is simply a motor controller. It was created to run any electric motor.

Yes but the pint/GT uses proprietary connectors therefore will need some DIY in order to make it work.

You can use any battery that fits in your build up to 20s! At this time there are a few manufacturers that make compatible upgraded batteries. 2 that we would recommend include Z Battery Solutions and The Board Garage.

Pev.dev is the best collection of information at this time and I would recommend searching there for common issues but if you have more specific needs feel free to reach out to us at support@makerspev.com

The BMS choice is ultimately up to the user but a few popular options at the moment are ZBMZ, the ennoid and changing an xr/pint bms to charge only.

The Makers PEV BMS is in the works and coming soon.

Yes we ship anywhere we can from the United States. International shipping rates will apply and are not included in our $15 flat rate shipping.

Though most of the connectors from an XR controller can be reused it will require quite a bit of DIY and is significantly harder.

The only part that is not compatible is the momentary switch on the XR. The Little FOCer uses a latching switch.

No, our product replaces it completely and does not work with it in any way. You can choose to use either the Littler FOCer or your FM controller, but you cannot use them together.

No, at this time we are here to support people in their own builds and provide the equipment needed to do so.

VESC is the software that the Little FOCer hardware runs on similar to how Linux is the operating system for many different computers.
