The A200S V3 is one of the smallest high current/voltage motor controllers available (110x40x26mm). Yet it packs a serious punch!

It has separate power and logic boards.

 

The A200S V3 was designed specifically for use in Featherweight and Heavyweight combat robots. It runs the extremely popular VESC®*-Project firmware.

Battle hardened with neutral cure silicone rubber.

 

This is the first design to move away from the standard JST connectors found on many VESC®*-Project designs. We found these tend to pull out in combat and they take up too much space on the PCB to make a compact design.

For this reason we have decided to replace ALL the connectors (apart from USB) with a single 20 pin Pico-Clasp connector. This is a locking connector which lets you fit as many or as few pins as you want.

So if you only want PPM control you only fit the PPM wires. Each unit comes with a connector shell and enough pre-crimped wires to populate the whole connector. We leave it up to you to decide which connections you want.

 

All IO is protected with TVS diodes.

The unit can be powered by USB from a laptop to allow tweaking settings without needing to connect main batteries. (Very useful when in the pits)

Wireless chip for control / programming using the VESC® Tool mobile app.

 

 

Quick tips on setup

!!ONLY USE 1 BEC, cut the 5v wire on all but one or the BEC can be damaged!!

Max battery cable length without additional capacitors is 1m (Battery wires should be short, thick and grouped together, motor wires should be long. So best to place controller near battery with long wires to wherever the motor is located.)

Please be careful when programming settings. Start at low currents and work up. Setting everything at max during initial setup is a bad idea.

We recommend detecting motors using the FOC motor setup wizard. This will automatically find the correct settings for your motor. If you have problems getting your particular motor setup please contact us and we will do our best to help.

If you experience ABS overcurrent faults a lot, then increase your switching speed to 60KHz. Just turning up the abs max current setting is not a good solution as you are only masking the root of the problem.

 

High voltage LiPo is extremely dangerous if handled incorrectly.

ALWAYS run with a fuse, especially for testing.

 

Current Handling

16S:

  • 100A for 10min+ continuous with no additional cooling   (A VESC®*6 manages only 40A in this test) 
  • 200A for 60s before thermal throttling
  • 200A+ continuous possible with additional cooling

12S Version has 25% lower resistance than the 16S model.
