0xCB 1337 design files

The KiCad project lives in the 0xCB-dev/0xCB-1337 repository on GitHub; these links point at the commit this page was built from.

0xCB 1337: common questions

What microcontroller does the 0xCB 1337 use?

The 0xCB 1337 is built around the TPS2553DBVR, from the AVR/Arduino family.

How big is the 0xCB 1337 PCB?

The 0xCB 1337 measures 62 × 62 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the 0xCB 1337?

53 components, from 26 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the 0xCB 1337 design files?

From the 0xCB-dev/0xCB-1337 repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the 0xCB 1337 design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the 0xCB 1337 without the hardware?

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