SHADOW SABRE 12FET — Early Access Batch for DIY Builds

Hey everyone,

Over the last few days we shared some of the internals, hardware details, and development progress of the SHADOW SABRE 12FET platform, and we really appreciate the discussions, suggestions, and feedback from the community.

After seeing the response, we decided to open a small early-access batch for a few serious builders and enthusiasts interested in testing the platform in real-world builds.

This is not intended to be a full-scale launch yet. The idea is mainly to get the controllers into actual projects, gather honest feedback, and continue improving the platform based on real community experience.

We’re especially excited to see what kind of DIY skateboard setups and compact high-power builds people come up with using the platform.

Current versions:

  • Base Model

  • Race Spec Version

Platform details:

  • Up to 126V platform

  • Compact high-current 12 FET architecture

  • CNC aluminum flat-base heatsink

  • Conformal coated electronics

The early-access batch also includes the SYMXPRESS Bluetooth programming module developed by our team for wireless communication and programming.

Initial setup guidance and tuning support will also be provided from our side for early users.

Datasheets and specifications are available on the webpage.

For anyone interested in the earlier hardware discussion, internals, and development updates, the original thread can be found here:

We’d love to see the controllers used in interesting DIY builds and pushed in real conditions by experienced users from the community.

Limited early-access batch is now open.

Shadow Sabre Dual Controller Setup now available for early-access testing with serious DIY builders and lightweight EV enthusiasts.

The setup currently includes:
• 2 × Shadow Sabre 12FET controllers
• CAN synchronization architecture
• Single throttle dual-drive operation
• SYMXPRESS wireless integration support
• VESC-based tuning workflow
• Compact high-power controller platform

This platform is currently being validated for:
• high-performance electric scooters
• esk8 platforms
• lightweight e-moto projects
• compact custom EV builds

The goal is to work closely with real builders and gather feedback around:
• thermal behavior
• throttle response
• dual-drive synchronization
• compact installation challenges
• tuning workflow
• long-term reliability under load

If you are working on a serious dual-drive or lightweight EV project and interested in testing the platform, check the compatibility workflow and setup details on:
