About the Tiny-Dimply-Qazy PCB

Tiny-Dimply-Qazy is an open source STM32 PCB design by ASH-ART, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 200 × 76.2 mm, with 90 components from 30 distinct parts.

Its main chip is the STM32F072CBTX, from the STM32 family. Other key parts include the XC6206PXXXMR-REGULATOR_LINEAR and USBLC6-2SC6. By type, the board carries 43 LEDs, 20 diodes, 5 resistors, 4 capacitors, 3 ICs and 3 connectors.

It belongs with the keyboards designs in this gallery.

From the project

10.5u 35% keyboard using an STM32f072 MCU

A 10.5u 35% keyboard PCB. A tribute to Lazydesigner's Dimple, and tominabox1 and whydobearsexplod's QAZ.

This PCB has been tested to work electronically, but requires further prototyping for fit and usability. The members of the PCB development team are not liable if you end up with a non-functional pcb. Order at your own risk. Support will not be provided but pull requests will be reviewed and possibly accepted.

Tiny-Dimply-Qazy: common questions

What microcontroller does the Tiny-Dimply-Qazy use?

The Tiny-Dimply-Qazy is built around the STM32F072CBTX, from the STM32 family.

How big is the Tiny-Dimply-Qazy PCB?

The Tiny-Dimply-Qazy measures 200 × 76.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Tiny-Dimply-Qazy?

90 components, from 30 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 Tiny-Dimply-Qazy design files?

From the ASH-ART/Tiny-Dimply-Qazy 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 Tiny-Dimply-Qazy design in my own project?

Yes, under the terms of its GPL-3.0 license, which ASH-ART chose for the repository.

Can I test firmware for the Tiny-Dimply-Qazy without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
