gkv4 represents a significant upgrade over the original gk with improved speed, a bigger screen, more gamepad buttons and hardware-accelerated 3D rendering.
gkv4 is a small, battery powered handheld gaming console running on a STM32MP2 MPU (dual Cortex-A35 cores with additional Cortex-M33 core). It runs a custom OS called gkos which allows near-instantaneous (MCU-like) cold boot times but is…

Gk pcbv3: common questions
What microcontroller does the Gk pcbv3 use?
The Gk pcbv3 is built around the STM32H7S7L8H6H, from the STM32 family.
How big is the Gk pcbv3 PCB?
The Gk pcbv3 measures 108 × 158.8 mm, has 6 copper layers and is 1.5584 mm thick.
How many components are on the Gk pcbv3?
276 components, from 89 distinct parts. The full bill of materials is listed on this page.
Where can I download the Gk pcbv3 design files?
From the jncronin/gk repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Gk pcbv3 design in my own project?
The repository has no license, so all rights stay with jncronin. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Gk pcbv3 without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
