Overview
Handystick panel is an open-source printed circuit board by kjoller, from the kjoller/handystick repository on GitHub. It is a 2-layer board of 49.5 × 45 mm with 58 parts on 32 nets, routed with 756 tracks and 74 vias.
It is built around the ATMEGA328P-AU. Its parts include 12 capacitors, 12 resistors, 8 connectors, 6 diodes and 4 switches. It belongs with the microcontroller boards boards and the AVR (ATmega, ATtiny) boards of this library.
Main components
1README
README.mdHandyStick is yet another small development board with an AtmegaX8 (Atmega88, Atmega168, Atmega328). The board is targeted towards use with vUsb, a software implemented USB stack.
It is cheap to manufacture, fitting two on a cheap 5x5cm 2-layer pcb, and using easy-to-source parts.
Possible uses:
- Using projects like USBAspLoader, you can get a USB programmable AVR board for less than $3 in parts.
- You can use this for USB HID-devices, such as joysticks, gamepads or even a full-featured MAME cabinet
- USB dataloggers
- For more ideas, see the vUSB web site.
The first panel is panelised with mouse bites (tab routing), so not all PCB services will take it. I have ordered the first batch on DirtyPCBs.
(For added vendor flexibility, it would be wise to panelize it using only silkscreen seperators. with just silkscreen, 5 should fit easily on a 5x10cm board, making it even cheaper.)

Questions
How big is the Handystick panel PCB?
It measures 49.5 × 45 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Handystick panel use?
58 parts, built around the ATMEGA328P-AU. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Handystick panel KiCad files?
From the kjoller/handystick repository on GitHub, at the commit this page was made from: the board is handystick_panel.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Handystick panel design in my own project?
Its repository states no licence, so its author keeps all rights: ask kjoller before reusing the design.
