Game2: common questions

What microcontroller does the Game2 use?

The Game2 is built around the ESP32-PICO-D4, from the RP2040/RP2350 family.

How big is the Game2 PCB?

The Game2 measures 58 × 104 mm, has 4 copper layers and is 1.2 mm thick.

How many components are on the Game2?

79 components, from 42 distinct parts. The full bill of materials is listed on this page.

Where can I download the Game2 design files?

From the aherbez/game2 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Game2 design in my own project?

The repository has no license, so all rights stay with aherbez. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Game2 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
