The archive with the current versions of the motor controller files (KiCAD version 10.0.4), Gerber files, CAD files and firmware files can be downloaded here (updated on 2026-06-26).
drive.google.com
There are two PCBs in two folders. The Gerber files for each board are in the "\VESC Shrimp_AMPLIFIER\Production files\Gerbers" and "VESC Shrimp_BRAIN\Production files\Gerbers" folders.
The KiCAD project files for each board are in the "\VESC Shrimp_AMPLIFIER" and "VESC Shrimp_BRAIN" folders.
The CAD files of other parts can by found in folders "Idividual Parts Footprints, Symbols, 3D CAD" in each board folder.
The Bluetooth module firmware file "Bluetooth_Firmware_nRF51822.hex" can be found in the "VESC Shrimp_BRAIN\Firmware" folder with flashing instructions in the "Readme.txt" file in the same folder.
Controller firmware files are "Works with Bafang Analogue Torque Sensors_6_06_#1 (2026-06-22).bin" and "Works with Bafang CAN Torque Sensors_6_06_#1 (2026-03-26).bin" are in the "VESC Shrimp_BRAIN\Firmware" folder. If you want to integrate this controller into the Bafang M620 motor there are also configuration files "motor_config_m620_6_06 (2026-06-23).xml" and "app_config_m620_6_06 (2026-06-23).xml" you can apply with the VESC Tool application to skip the controller setup for this motor.
More details about the firmware can be found in the "Readme.txt" file in the "VESC Shrimp_BRAIN\Firmware" folder.
The achieve also has CAD files of the 3D printed parts for Bafang M620 motor integration if you want to install this controller into a Bafang M620 motor.

Guys, the time has come! We need to design the most power dense motor controller ever created and hit the world record!
The controller must have the shape and size to fit inside most middrive motors on the market and have at least 10kW of power! Unfortunately there is no solution on the market would serve such purpose. There are some really small controllers, but usually they either have not suitable shape, or they are still not small enough, or not capable for 10 kW (and even half of it). And we need no compromises in terms of shape, size, integration and power for the middrive motors!
Fortunately it looks like there are components we can use to make exactly what we want!
Thanks to the DirectFETs shape, size and design (with the thick copper conductive housing) and specifically shaped terminals it looks like we can pack 10kW of power in less than Cricket lighter volume and sculpt it in exactly the shape we need without compromising and obstructing the current flow! The footprint of the whole controller (AMPLIFIER and BRAIN boards minus bulk capacitors) can be no bigger that the actual footprint of the MOSFETs and the thickens of 2 regular stacked boards with interconnects with tall components facing inside the stacked boards!
In order to shrink it to extreme and make the controller integration more flexible there will be no connectors, only soldering pads you can solder wires to and route them how you want. The bulk capacitors are also going to be separate module or modules you can size and connect to the wires and place it where those fit best.
These terminals design and the transistors configuration allow to route the high current flow the proper way and stack the components under those at the same time occupying the whole space in between the stacked boards and providing the freedom for the cables management at the same time creating the most extreme power density ever created by humanity!
And the coolest part is you can cram all this monstrous power even in the tiny Bafang M820!
Do you think guys we can do this and bring the INNOTRACE controllers to the next level?
