About the Cart prototype PCB

Cart prototype is an open source PIC PCB design by alttpo, published on GitHub under the MIT license. It is a 2-layer board measuring 101.5 × 83 mm, with 40 components from 10 distinct parts.

Its main chip is the PIC12F629-ISN, from the PIC family. Other key parts include the SN74LVC4245A and AMS1117-3.3. By type, the board carries 18 capacitors, 9 ICs, 6 resistors and 1 connector.

Cart prototype: common questions

What microcontroller does the Cart prototype use?

The Cart prototype is built around the PIC12F629-ISN, from the PIC family.

How big is the Cart prototype PCB?

The Cart prototype measures 101.5 × 83 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Cart prototype?

40 components, from 10 distinct parts. The full bill of materials is listed on this page.

Where can I download the Cart prototype design files?

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

Can I use the Cart prototype 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 Cart prototype 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.
