USB Fusion is a 5V power injector for high-current USB devices, like The Sol Keyboard.
For build details, please follow the build guide here
This device does not follow USB protocol. If you use a faulty or incorrect power source, your keyboard or computer may break.
Fusion has been updated to include some new safety features:
- USB Filter/ESD Protection
- Main PTC Fuse
- Secondary USB PCB trace fuse
- 3D-Printed base
The basics: The device bypasses the power limit of your computer's USB port and supplies the keyboard with power from SATA or a wall adapter. This allows Sol to reach maximum brightness. The following ports will be soldered onto the board: 1 USB-A, 1 USB-B, 2 USB-C, 1 5.5mm barrel power, 1 SATA power. To use, plug in one of each:
1. Type B or Type C to PC
2. SATA or Barrel Connector to power source
3. Type A or Type C to keyboard
Plug in the keyboard last, to allow USB to initialize properly.
Use only one of each port, to prevent damage to devices. (Example: Connecting both SATA and 5.5mm barrel may damage both power sources.) This is not a USB Hub. A motherboard USB header and 3-pin 5V (low speed) fan port are also available on the board. The holes are sized specifically for a 2.5in drive bay, with M3 mounting holes.
Use a 5.5mm power adapter, 5V, at least 4A capability.
