About the Another AT2XT PCB

Another AT2XT is an open source PIC PCB design by hkzlab, published on GitHub under the CC-BY-NC-4.0 license. It is a 2-layer board measuring 37.1 × 17.5 mm, with 9 components from 9 distinct parts.

Its main chip is the PIC12F629, from the PIC family. By type, the board carries 2 connectors, 2 capacitors, 1 IC, 1 fuse, 1 jumper and 1 diode.

It belongs with the keyboards designs in this gallery.

Another AT2XT Keyboard adapter PCB

This is nothing more than another PCB for the AT2XT project you can find HERE.

I needed something slightly smaller than what provided for the original project, and that did not need as many connector cables. So I've designed this to cater to my needs.

I take NO responsibility for what happens if you decide to build and use this card. Your computer might crash, catch fire or be destroyed in other nasty ways. You're encourauged to take what you deem fit from this, and use it in your projects!

Another AT2XT: common questions

What microcontroller does the Another AT2XT use?

The Another AT2XT is built around the PIC12F629, from the PIC family.

How big is the Another AT2XT PCB?

The Another AT2XT measures 37.1 × 17.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Another AT2XT?

9 components, from 9 distinct parts. The full bill of materials is listed on this page.

Where can I download the Another AT2XT design files?

From the hkzlab/Another_AT2XT repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Another AT2XT design in my own project?

It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Another AT2XT 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.
