MNT Pocket Reform Mainboard 2.0

The Long-Awaited Upgrade For Your MNT Pocket Reform Mini Laptop Is Finally Here.

With this new version 2.0 of the MNT Pocket Reform Mainboard, you get a modernized power system adapted from the MNT Reform Next as well as more ports, more stability, more everything. A detailed list of features (incl. changes) can be found below.

The Pocket Reform Mainboard 2.0 is not just an upgrade, it has a lot more to offer. Let's see:

Single Cable Desktop Docking

Combined with processor modules such as RCORE/RK3588, the MNT Pocket Reform Mainboard 2.0 supports DisplayPort Alt-Mode, USB, and Power/Charging over the same USB-C cable. You can also connect a second external monitor via Micro-HDMI.

Advanced Hacking Comfort

Flash firmware and debug the System Controller, USB bootloaders, and the serial console (with built-in USB-UART converter)—without opening the case. All these functions can be digitally switched to the USB-C ports on demand.

Pocket Reform Upgrade

You can upgrade your Pocket Reform or use the Mainboard 2.0 as a standalone single board computer with the new automatic charger module bypass and integrated power button. Add any of our processor modules plus a USB-C power supply and you're good to go.

Note: If you ordered an MNT Pocket Reform laptop after 2026-04-28 and it hasn't been shipped yet, it will automatically contain the latest 2.0 version.
