Board Overview

The adapter has an FFC connector on each side:

Two additional headers are broken out on the board:

Header	Labels	Purpose
HDMI power	+5V / GND	Connect the supplied 5V power lead here to power the HDMI dongle. Not required for the VGA dongle or no-cut kit.
F18A audio	AOUT / AGND	F18A audio output pass-through, for wiring to the HDMI dongle's audio input.

Installation

1. Connect the F18A MkI's 22-pin FFC output cable to the adapter's F18A-side FFC connector.
2. Connect the included (or an optional longer) PICO9918 FFC cable between the adapter's PICO9918-side FFC connector and your chosen accessory — VGA dongle, HDMI dongle, or no-cut kit.
3. If using the HDMI dongle, connect the supplied 5V power lead to the adapter's +5V/GND header and wire the F18A's audio output to the AOUT/AGND header for audio pass-through.
4. Power on your F18A-equipped system as usual.
