About the Elektronika-1 PCB

Elektronika-1 is an open source TI MSP430/CC PCB design by BenjaminSoelberg, published on GitHub under the GPL-3.0 license. It is a 4-layer board measuring 29.5 × 29.5 mm, with 14 components from 12 distinct parts.

Its main chip is the MSP430FR2433, from the TI MSP430/CC family. Other key parts include the AS1115. By type, the board carries 4 capacitors, 3 resistors, 2 ICs, 1 crystal, 1 connector and 1 battery holder.

It belongs with the wearables, test & measurement and retro computing designs in this gallery.

From the project

A replacement module for the USSR vintage LED watch Elektronika-1 anno 1978

It has been my daily driver for a few months by now with no problems what so ever.

It can show time, date and year which was more or less what you got in the original.

The module is based around: Texas Instruments MSP430fr2433 micro controller Austria Micro Systems AS1115 64 bit LED driver Vintage Hewlett Packard HP-5082-7414 4x7 segments + dot display CR2032 battery

Elektronika-1: common questions

What microcontroller does the Elektronika-1 use?

The Elektronika-1 is built around the MSP430FR2433, from the TI MSP430/CC family.

How big is the Elektronika-1 PCB?

The Elektronika-1 measures 29.5 × 29.5 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Elektronika-1?

14 components, from 12 distinct parts. The full bill of materials is listed on this page.

Where can I download the Elektronika-1 design files?

From the BenjaminSoelberg/elektronika-1 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Elektronika-1 design in my own project?

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

Can I test firmware for the Elektronika-1 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug TI MSP430/CC firmware against it before you order a PCB.
