UHID Board Overview


USB 2.0 interface

50 connections arranged in an open pin-header format allowing multiple varieties of standard connector to be used.

Connections can be assigned as:

  • Keyboard key
  • Gamepad Button
  • Gamepad analog axis with or without auto-calibration and center dead-zone.
  • Mouse button (including double-click)
  • Quadrature Mouse Pair. X or Y axis. Normal or reverse direction.
  • Quadrature left/right button presses.
  • PC-controlled LED output using special software
  • PC Num/Scroll/Caps lock LEDs
  • U-HID locally-controlled LED output based on the state of any switch.
  • 5 Volt output (30ma max)
  • Ground
  • No special drivers or application changes needed except for PC-controlled LEDs which has an API with code examples.
  • Simple open pin-header connectors allow use of separate or composite modular wiring harnesses.
  • U-Config configuration utility allows the connections to be configured for each device type, and keycodes and other attributes set.
  • Switches handled by super-fast logic using an individual de-bounce state counter for each input giving ultimate performance for gaming applications.
  • No key ghosting or blocking ever.
  • Advanced keycode/button programming with in-built shift feature. Includes macro capability
  • 12-bit analog axis support
  • Configuration utiity interacts real-time with the board and all settings stored instantly in Flash ROM on the board.
  • Single Mini-USB connector for PC (or MAC) connection. No separate power needed
  • 50 Truly independent inputs allow all switches to be commoned to ground. No matrix or diodes
  • Modular 8-way + ground harnesses available.
  • Extended switch harnesses available.
  • ESD protected inputs. Vital for high-footfall public applications.
  • All settings stored in Flash ROM and retained after power-off.
  • Configuration can be changed on-the-fly using a command-line. The board can assume a completely different layout instantly.
  • Simple-to-use PC Configuration application.
  • Up to 8 boards can be connected. All are configured using the same U-Config utility.

Advanced Features:

Key and Button functions can have one primary and one secondary code assignment.
Secondary assignments are invoked by first activating a “U-HID Shift” connection.
Any connection can be assigned as a shift.
Unique separately-programmable “button down” and “button up” events allow use of all types of normally-closed, normally-open, or active high/low controls.
“Button down” and “button up” can be separately assigned as primary or secondary codes.
Controls can be assigned as “normal” or “pulse”.
Toggle (push on-push off) and flip-flop modes available.
Programmable analog offset and scale factor for all analog axes.
X and Y axes can be configured with adjustable center dead-zone and auto-calibration.
Extended macro capability.
User-upgradeable firmware for future enhancements and customizations.

Examples of control types which can be connected:

  • Pushbuttons
  • Switch-type joysticks
  • Toggle switches
  • Toggle switches with integral LED (does not require a second connection for the LED)
  • Momentary pushbuttons with integral LED (LED can be controlled without any host application, or can be host-controlled)
  • LEDs associated with a switch. (LED can be controlled without any host application)
  • LED indicators driven by a PC application.
  • Other devices can be controlled either directly or via an external high-current driver
  • Analog joysticks
  • Incremental Rotary encoders (Spinners).
  • Low-resolution rotary encoders (360 degree volume control type)
  • 12-way or N-way rotary switches used as encoders (requires simple diode circuit)
  • Trackballs
  • Pots
  • Optical steering wheels
  • Pot-type steering wheels
  • Pot-type throttle pedals
  • Analog Voltage sources (0-5 volts).
  • TTL logic signals.

Control counts which can be configured:

Total 50 connection pins.

Max 8 analog axes on 50 possible pins (Windows limitation)
Max 32 Gamepad buttons on 50 possible pins (Windows limitation)
Max 8 Quadrature mouse devices on 16 possible pins out of the 50.
Max 3 Quadrature mouse axes (X, Y and Z, Windows limitation)
Max 50 keyboard keys on 50 possible pins.
Max 16 LEDs in any combination of PC or U-HID controlled. (USB 500 mA current limitation).
Max 50 low-current output drivers.
