About the Shiny avr PCB

Shiny avr is an open source AVR/Arduino PCB design by tibordp, published on GitHub under the BSD-2-Clause license. It is a 4-layer board measuring 54.4 × 20.3 mm, with 39 components from 16 distinct parts.

Its main chip is the ATtiny85-20PU, from the AVR/Arduino family. Other key parts include the AMS1117-3.3 and STM32F103C6Tx. By type, the board carries 17 resistors, 13 capacitors, 4 ICs, 2 connectors, 2 diodes and 1 crystal.

It belongs with the usb & debug tools designs in this gallery.

From the project

USB programmer for ATtiny25/45/85/24/44/84

USB AVR ISP programmer specifically designed for ATtiny25/45/85 and ATtiny24/44/84/241/441/841 microcontroller families in DIP packages.

Blasphemeously designed with an STM32 microcontroller instead of an another AVR.

Shiny AVR programmer provides an 16 MHz clock signal, which allows programming chips that have had their fuse bits set to require an external crystal or clock signal.

Shiny avr: common questions

What microcontroller does the Shiny avr use?

The Shiny avr is built around the ATtiny85-20PU, from the AVR/Arduino family.

How big is the Shiny avr PCB?

The Shiny avr measures 54.4 × 20.3 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Shiny avr?

39 components, from 16 distinct parts. The full bill of materials is listed on this page.

Where can I download the Shiny avr design files?

From the tibordp/shiny-avr repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Shiny avr design in my own project?

Yes, under the terms of its BSD-2-Clause license, which tibordp chose for the repository.

Can I test firmware for the Shiny avr 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.
