About the ATtiny85UNOProgrammer PCB

ATtiny85UNOProgrammer is an open source AVR/Arduino PCB design by Hengy2016, published on GitHub. It is a 2-layer board measuring 58.4 × 22.9 mm, with 14 components from 11 distinct parts.

Its main chip is the ATtiny85, from the AVR/Arduino family. By type, the board carries 4 LEDs, 4 resistors, 3 connectors, 2 capacitors and 1 IC.

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

From the project

Simple board designed in Kicad to program ATtiny85 from an Arduino UNO

Simple little board for an ATtiny85 programmer for a UNO (plugs directly into the UNO )

Status LEDs are based on the default pinouts in ATTinyCore board as per the ArduinoISP example sketch copied here : > >// Put an LED (with resistor) on the following pins: > >// 9: Heartbeat - shows the programmer is running > >// 8: Error - Lights up if something goes wrong (use red if that makes sense) > >// 7: Programming - In communication with the target >

ATtiny85UNOProgrammer: common questions

What microcontroller does the ATtiny85UNOProgrammer use?

The ATtiny85UNOProgrammer is built around the ATtiny85, from the AVR/Arduino family.

How big is the ATtiny85UNOProgrammer PCB?

The ATtiny85UNOProgrammer measures 58.4 × 22.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ATtiny85UNOProgrammer?

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

Where can I download the ATtiny85UNOProgrammer design files?

From the Hengy2016/ATtiny85UNOProgrammer repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the ATtiny85UNOProgrammer design in my own project?

The repository has no license, so all rights stay with Hengy2016. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the ATtiny85UNOProgrammer 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.
