• Advanced Firmware Features:
o Key mappings: you can map any key to another key, to mouse
movement or to a macro (see full manual for limitations). Users can
turn a Qwerty keyboard into a Dvorak or Colemak one with a simple
command.
o Timers: periodically send a key, mouse movement or macro. There
can be up to 4 timers.
o Macro: a sequence of keys and/or mouse movements used in other
commands such as key mappings or timers.
o Layer: group a set of settings together so you can switch between
them quickly using shortcuts.
o Repeat: use a key to toggle on/off to generate fast succession of
keystrokes. Useful in gaming.

The Adapter incorpotes a 0.96 inch TFT color display. It shows several
pages of useful information. The main page shows the status of Blue-
tooth and USB connectivity, whether they are enabled, connected and
activated. There is a screen displaying useful USB information such as
voltage and cumulated power consumption.

Main Functions
• Turning a USB keyboard/mouse into a Bluetooth one.
• Acting as a USB to USB bridge. Switching between BT and USB
• Key mappings, macros, timers, layers and output throttling.
Key Features
• Based on Bluetooth 5.2 (Bluetooth Low Energy or BLE) with reduc-
tion in power consumption and fast connection time.
• Works with all types of hosts including MacOS, iOS (iPad & iPhone),
Android tablets/smartphones, all versions of Windows and Linux as
long as they have Bluetooth 4.x and up. Note that Windows 7 or prior
supports only BT 2.x so you need at least Windows 8.
• Compatible with all types of USB keyboards including those with a
built-in hub. See the Compatibility list on our web site for a list key-
boards we have tested. Additional devices connected to a keyboard's
built-in hub is not officially supported so it may or may not work.
• Most media keys on keyboard will work including Volume +/-, Mute,
Play/Stop, Previous/Next, Browser, Calculator, Home, Help, Search
and Sleep. Programmable keys (for example, those marked as G1, G2,
... on some Logitech keyboards) will not work unless they are config-
ured as standard keys.
• Many keyboard-emulating USB devices will work if they appear as
keyboards in the operating system. Those include keypads, foot ped-
als, bar code readers, magnetic strip readers, and PS2 to USB adapters.
Most 2.4G wireless dongles (e.g., Logitech Unifying Adapter, HP
wireless keyboard adapter) will also work.
• No keycode pairing: pairing just works without typing in any code.
Currently this is the only pairing option. If security is a concern,
caution must be taken to make sure the adapter is paired with the
• Press and hold for 10 seconds: reset all settings to factory default.
USB-USB Bridging
When plugged into a laptop, the USB male port shows up as a compos-
ite keyboard/mouse device. If activated, any keystrokes or mouse move-
ments will be output to this port, effectively bridging the keyboard/
mouse to the host computer with all the useful features such as key
mapping and layers that are not available in most keyboards.
Quick Start Guide
As soon as the adapter is powered on, if it is not connected to a host,
during the first 30 seconds, it will advertise its present and become
available for pairing. Follow the process below to pair:
• Turn on the adapter with or without a keyboard connected. Screen
should display the VID/PID of the keyboard, or error information if it
fails to detect or enumerate the keyboard.
• On the host, search for Bluetooth devices. The name of the adapter is
ADAPTER_nnnn where nnnn is the last 4 digits of its MAC address.
• After the host finds the adapter, select it and click "pair". There is no
need for any pairing code. If pairing succeeds, the adapter will then
be connected to the host and ready for use. The screen will also show
that status.
If you can't find the adapter in the host's list of Bluetooth devices, make
sure the host has BT 4.0 and up. If the adapter is listed but fails to pair,
make sure the host supports HID keyboard/mouse. Some low-cost
smartphones/tablets have Bluetooth but support only earphones not
keyboards.
Pairing needs to be done only once. Next time when the adapter is
turned on, it will connect to the paired host if it is available.
Once paired, if you would like to pair it with a different host, you must
