About the AutoFlyer PCB

AutoFlyer is an open source AVR/Arduino PCB design by mribble, published on GitHub. It is a 2-layer board measuring 35.6 × 17.8 mm, with 18 components from 15 distinct parts.

Its main chip is the ATTINY44-20SSU, from the AVR/Arduino family. Other key parts include the LD1117S33TR_SOT223 and H-Bridge-DMHC3025LSD. By type, the board carries 4 capacitors, 3 ICs, 3 connectors, 3 resistors, 2 crystals and 2 diodes.

From the project

The Electric Eel Wheel 5 is an electric spinning wheel that converts fiber (an example being sheep's wool) into yarn. This site contains the open source files for this project. It includes source code, CAD models, PCB design files, and documentation source files.

AutoFlyer: common questions

What microcontroller does the AutoFlyer use?

The AutoFlyer is built around the ATTINY44-20SSU, from the AVR/Arduino family.

How big is the AutoFlyer PCB?

The AutoFlyer measures 35.6 × 17.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the AutoFlyer?

18 components, from 15 distinct parts. The full bill of materials is listed on this page.

Where can I download the AutoFlyer design files?

From the mribble/ElectricEelWheel5 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the AutoFlyer design in my own project?

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

Can I test firmware for the AutoFlyer 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.
