PikoBall-Tiny USB HID Trackball With RGB Backlight

What is it?

This is a tiny open-source USB trackball with colorful backlight, it is built around ch32v003 mcu and rv003usb framework.

Why did you make it?

It was made because I needed some very small USB mouse for my
Raspberry Pi. This trackball turned out to be a possible alternative and
required much less space.

What makes it special?

• Pre-flashed with USB HID code
• RGB backlight(Changing colors, white, no backlight)
• Firmware source available for modification.
• Compatible with Windows, Linux(including Raspberry Pi), and smartphones
• Schematics available from the Datasheet section
• 3D printable enclosure
• Unique Vendor and Product ID, purchased from MCS Electronics.
• 4x M2 mounting holes
• Mouse right button, mouse left button(press left key or trackball), change sensitivity, change backlight

Warning

• The trackball is not great for big screens and small icons because
  the movement is not smooth enough. Works best for smaller screens(RPI or
  phone).
