The EAS MAX PCB is the custom electronics board at the heart of the EAS MAX speed loader system. It handles motor control, BB counting, display output, and user input in a single compact layout that mounts directly into the printed housing.

This listing is for the PCB kit only — no 3D printed parts, no battery. The STL file pack is sold separately. Three versions are available depending on how much you want to solder yourself.

WANT TO MAKE YOUR OWN PCB?

The Gerber files for the EAS MAX PCB are available separately. Download them and have the board manufactured at your preferred PCB supplier — JLCPCB, PCBWay, or similar. You source and solder all components yourself using the parts list.

CHOOSE YOUR VERSION
BAREBONE PCB
Unpopulated PCB only. All components must be sourced and soldered by you. For experienced builders who want full control or already have components on hand.
PCB WITH SMD SOLDERED
PCB with all surface-mount components pre-soldered. You solder the through-hole connectors and modules yourself. A good middle ground if you're comfortable with basic soldering.
FULL ELECTRONIC KIT
SMD components pre-soldered + all through-hole components included — ESP32-S3 SuperMini, DRV8833, voltage regulator, and all remaining PCB parts. Just solder everything together and you're ready to build.

WARRANTY & LIABILITY
The PCB carries a 14-day warranty covering manufacturing defects from the date of delivery. This does not cover solder joints, pads, traces, or any damage caused during assembly. If you damage the board while soldering — lifted pads, bridged joints, overheated components — that is not covered. I offer these kits so you can build it yourself without having to buy PCBs in bulk. Handle with care.
