About the Board attiny2313a

Board attiny2313a is an open source AVR/Arduino PCB design by SamantazFox, published on GitHub under the BSD-3-Clause license. It is a 2-layer board measuring 20.1 × 20 mm, with 15 components from 10 distinct parts.

Its main chip is the ATtiny2313A-SU, from the AVR/Arduino family. Other key parts include the TP4056. By type, the board carries 5 resistors, 3 capacitors, 2 ICs, 2 diodes, 1 connector and 1 switch.

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

From the project

A micro-controller, a 8x8 led matrix and a battery around your neck for maximum style !

Introduction Project's Description Folders Known Issues * To Do

This project is a simple customizable necklace, based on an AtTiny2313a (or alternatively an ATtiny48/88) and a 8x8 dot LED matrix.

The very first idea came from furrtek's mind, called jewelmatrix. You can find his project on his website (french).

The idea behind this project was to improve Furrtek's project and add a few options, such as a rechargeable Li-Ion battery (instead of a coin cell) and a cross-platform tool to add custom patterns on the fly, without the need to rebuild and flash the ATtiny every time.

Board attiny2313a: common questions

What microcontroller does the Board attiny2313a use?

The Board attiny2313a is built around the ATtiny2313A-SU, from the AVR/Arduino family.

How big is the Board attiny2313a?

The Board attiny2313a measures 20.1 × 20 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Board attiny2313a?

15 components, from 10 distinct parts. The full bill of materials is listed on this page.

Where can I download the Board attiny2313a design files?

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

Can I use the Board attiny2313a design in my own project?

Yes, under the terms of its BSD-3-Clause license, which SamantazFox chose for the repository.

Can I test firmware for the Board attiny2313a 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.
