About the Jeden board

Jeden board is an open source AVR/Arduino PCB design by Wojtekb30, published on GitHub under the Custom license license. It is a 2-layer board measuring 62.5 × 61.5 mm, with 29 components from 15 distinct parts.

Its main chip is the ATmega328-P, from the AVR/Arduino family. Other key parts include the FT232RL. By type, the board carries 7 resistors, 6 connectors, 6 capacitors, 3 diodes, 2 ICs and 2 LEDs.

It belongs with the dev boards & breakouts and usb & debug tools designs in this gallery.

From the project

KiCad hardware project. A ATMega328P-based development board with Arduino Uno's functionality.

[photo of the board after manufacturing, the LED 1 was not soldiered in the factory but lack of it does not affect the functionality]

I successfully burned the Arduino bootloader onto the board by using a genuine Arduino Uno as ISP programmer.

In Arduino IDE I uploaded the ISP programmer software into the Uno, then wired it to my board's ISP pins, then chose Arduino Uno as the board's model and clicked "Burn the bootloader".

Jeden board: common questions

What microcontroller does the Jeden board use?

The Jeden board is built around the ATmega328-P, from the AVR/Arduino family.

How big is the Jeden board?

The Jeden board measures 62.5 × 61.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Jeden board?

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

Where can I download the Jeden board design files?

From the Wojtekb30/Jeden-board repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Jeden board design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Jeden board 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.
