V1: common questions

What microcontroller does the V1 use?

The V1 is built around the PIC12F629-I/SN, from the PIC family.

How big is the V1 PCB?

The V1 measures 101.5 × 105.4 mm, has 2 copper layers and is 1.2 mm thick.

How many components are on the V1?

61 components, from 25 distinct parts. The full bill of materials is listed on this page.

Where can I download the V1 design files?

From the alttpo/pico-cart-snes repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the V1 design in my own project?

Yes, under the terms of its MIT license, which alttpo chose for the repository.

Can I test firmware for the V1 without the hardware?

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