About the Mad PCB

Mad is an open source AVR/Arduino PCB design by 0x007E, published on GitHub under the CC-BY-NC-4.0 license. It is a 2-layer board measuring 36 × 47 mm, with 35 components from 18 distinct parts.

Its main chip is the ATtiny__06-S, from the AVR/Arduino family. By type, the board carries 12 transistors, 10 resistors, 4 capacitors, 3 diodes, 2 connectors and 1 IC.

It belongs with the displays & leds designs in this gallery.

From the project

Matrix Display

The MAD project is based on a pcb with an ATtiny406/ATtiny1606 and a Matrix LED Display. It can be used to display data sent over SPI or UART. The display also implements a small amount of characters from the ASCII table and also has internal space (EEPROM) for 16 special characters that can be programmed.

There are two parts of the hardware. The pcb and the housing of the MAD. The pcb is created with KiCAD and the housing with FreeCAD. The software is programmed with Microchip (Atmel) Studio. All files are built with github actions so that they are ready for a production environment. The…

Mad: common questions

What microcontroller does the Mad use?

The Mad is built around the ATtiny__06-S, from the AVR/Arduino family.

How big is the Mad PCB?

The Mad measures 36 × 47 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Mad?

35 components, from 18 distinct parts. The full bill of materials is listed on this page.

Where can I download the Mad design files?

From the 0x007E/mad repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Mad 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 Mad 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.
