About the Rcc PCB

Rcc is an open source AVR/Arduino PCB design by 0x007E, published on GitHub under the CC-BY-NC-4.0 license. It is a 2-layer board measuring 25.4 × 25.4 mm, with 11 components from 7 distinct parts.

Its main chip is the ATtiny402-SS, from the AVR/Arduino family. By type, the board carries 3 capacitors, 3 resistors, 2 diodes, 1 IC, 1 battery holder and 1 switch.

From the project

RGB Color Cube

The RCC project is based on a pcb with an ATtiny402 and two RGB LEDs that are controlled via SPI-bus. The cube itself is controlled over a single push-button that enables/disables the cube and can be used to setup the color and intensity of the rgb leds.

With the RCC-Simulator different functions (e.g. power-on/-off, ...) can be simulated within a webpage.

There are two parts of the hardware. The pcb and the housing of the RCC. The pcb is created with KiCAD and the housing with FreeCAD. The software is programmed with Microchip (Atmel) Studio. All files are built with github actions so that…

Rcc: common questions

What microcontroller does the Rcc use?

The Rcc is built around the ATtiny402-SS, from the AVR/Arduino family.

How big is the Rcc PCB?

The Rcc measures 25.4 × 25.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Rcc?

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

Where can I download the Rcc design files?

From the 0x007E/rcc repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Rcc design in my own project?

It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Rcc 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.
