HandyStick 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.
- 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.)
