Expected release date is 28th Jul 2019

We are now accepting pre-orders for the revised version V2.1 which has some minor improvements to the logic board to improve reliability.

It now has the pinout of each connector on the top and the programming connector has been changed to a row of 0.1" headers.

Please note that we will not receive the PCBs for this new model until around the end of July. So please be patient.


The A200S V2.1 is one of the smallest BLDC motor controllers available (110x80x38mm). Yet it packs a serious punch!

It has separate power and logic boards.



You can order all parts of the A200S individually.

Current handling: 

6S 12S 16S
250A 250A 200A


Comes with 3x XT90 connectors, 3x 5mm lugs and nuts with covers.
