About the LogicModule PCB

LogicModule is an open source AVR/Arduino PCB design by JanBurp, published on GitHub. It is a 2-layer board measuring 29.2 × 110.1 mm, with 59 components from 32 distinct parts.

Its main chip is the ARDUINO_NANO_V2.X, from the AVR/Arduino family. By type, the board carries 23 resistors, 17 diodes, 11 connectors, 4 transistors, 3 switches and 1 module.

It belongs with the audio designs in this gallery.

From the project

An eurorack logic module with several logic functions and a clock divider mode. Build around an arduino nano. So could be reprogrammed.

An Eurorack module based around a Arduino Nano.

With AND, OR, XOR logic functions, a Flip Flip (Q), a Clock Divider mode, and more.

- Basic logic funcions AND, OR, XOR (using the first inputs on the left side). - Flip Flop (Q) (first input will SET, second input will RESET). - NOT input, or MODE button, to inverse all logic outputs (NAND, NOR, NXOR, NQ) - CLOCK input, when present, all Logic outputs only are HIGH when CLOCK is HIGH - RESET button to reset Q and CLOCK

LogicModule: common questions

What microcontroller does the LogicModule use?

The LogicModule is built around the ARDUINO_NANO_V2.X, from the AVR/Arduino family.

How big is the LogicModule PCB?

The LogicModule measures 29.2 × 110.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the LogicModule?

59 components, from 32 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 LogicModule design files?

From the JanBurp/MorphaLogic 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 LogicModule design in my own project?

The repository has no license, so all rights stay with JanBurp. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the LogicModule 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.
