About the Optiem PCB

Optiem is an open source AVR/Arduino PCB design by Elektroniikkakerho, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 60.2 × 54.1 mm, with 42 components from 7 distinct parts.

Its main chip is the ATTINY861-S, from the AVR/Arduino family. By type, the board carries 32 diodes, 4 resistors, 3 connectors, 1 IC, 1 fuse and 1 capacitor.

From the project

Haalarimerkki sinisellä ledisalamalla!

Levyyn on myös suunniteltu kytkin, jolla voisi vaikka sammuttaa laitteen tai toimittaa muuta toiminnallisuutta, mutta näitä ei ole koodissa toteutettu vieläkään.

Kuusipinninen liitin on ohjelmointia varten ja sitä kautta ohjelma siirretääm mikrokontrollerille. Ohjelmointi hoituu Arduinon ISP:n kautta.

Nyt kun sinulla on piirilevy, laitetaampa siihen komponentit kiinni.

Optiem: common questions

What microcontroller does the Optiem use?

The Optiem is built around the ATTINY861-S, from the AVR/Arduino family.

How big is the Optiem PCB?

The Optiem measures 60.2 × 54.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Optiem?

42 components, from 7 distinct parts. The full bill of materials is listed on this page.

Where can I download the Optiem design files?

From the Elektroniikkakerho/Led-merkki repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Optiem design in my own project?

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

Can I test firmware for the Optiem 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.
