+# The Pico HID PS/2 Bridge
+
+The Pico HID Bridge is a special case of the [Pico HID](pico_hid.md).
+It is a simple PS/2-only emulator with a USB interface. Unlike generic [Pico HID](pico_hid.md)
+and legacy [Arduino HID](arduino_hid.md), it doesn't require SPI wiring with GPIO.
+
+At one end it connects to USB-A on PiKVM, on the other side it has two PS/2 connectors for keyboard and mouse:
+
+
+
+In addition, on PiKVM V2+, the use of Pico the HID Bridge does not exclude the use of a regular USB OTG port with Mass Storage emulation.
+Thus, on V2+ you will be able to use PS/2 and USB Mass Storage at the same time, and even switch between OTG HID and [Pico HID](pico_hid.md).
+
+
+-----
+## Making the Bridge
+
+* *x1* [Raspberry Pi Pico board](https://www.raspberrypi.com/products/raspberry-pi-pico/) with soldered pins.
+* *x1* USB-A to Micro-USB cable.
+* *x1* 3.3V/5V bi-directional logic level shifter [like this](https://learn.sparkfun.com/tutorials/bi-directional-logic-level-converter-hookup-guide/).
+* *x2* PS/2 cable with male connector.
+* *x2* Small dip jumpers.
+
+Make sure that the level shifter pinout matches the scheme, and connect everything according to the [Pico pinout](https://pico.pinout.xyz).
+
+```

+
+```
+
+You can take the 5V power line from one of the PS/2, for example from the keyboard,
+or from both at once, but use a multimeter to make sure that both PS/2 female
+connectors have the same line.
+
+
+
+PS/2 female socket pinout on the motherboard is the same for the keyboard and the mouse.
+A purple socket usually corresponds to the keyboard, and a green one to the mouse.
+If your motherboard only has one port, it's probably universal and can be used for both
+the keyboard and the mouse. Most likely, it will be painted both colors.
+
+Use a multimeter to determine the purpose of the wires in your PS/2 cables.
+
+A good idea is to mount the level shifter on top of the Pico, as in this photo:
+
+
+
+Finally, install DIP jumpers to soldered pins of the Pico to enable PS/2 and Bridge modes:
+
+* `GP2 <-> GND`
+* `GP5 <-> GND`
+
+Like this:
+
+

+## Flashing the firmware
+
+To upload the firmware to Pico HID, you can use any computer with a USB port.
+
+1. [Download](https://github.com/pikvm/kvmd/releases) the latest release of the firmware. The file is called `pico-hid.uf2`.
+2. Press and hold the white button on the Pico board.
+3. While still holding the button, plug it in the computer using a USB cable.
+4. Release the button.
+5. The Pico board appears as a flash drive on your computer.
+6. Copy the `pico-hid.uf2` file to this flash drive.
+7. Safely eject the USB device.
+
+
+-----
+## The final steps
+
+Connect the Pico HID to the target host using PS/2 cable and USB to USB-A port on PiKVM.
+
+Add following lines to the PiKVM configuration and reboot it:
+
+* `/etc/kvmd/override.yaml`:
+ ```yaml
+ kvmd:
+ hid:
+ type: serial
+ device: /dev/kvmd-hid-bridge
+ ```
