KOI Close Up¶
Let’s take a closer look at the AI Camera KOI.
This is the default orientation of KOI.
The camera can be rotated from 0° to 180°. Be careful of the cable when rotating the camera.
Front Camera Mode¶
When both the camera and the display are facing towards you, the KOI is set up in Front Camera mode.
This is usually used in face detection or visual recognition.
Back Camera Mode¶
Wehn the camera and the display are facing the opposite the direction, the KOI is set up in Back Camera mode.
This is usually used in object classification, qr code/barcode recognition or line tracing.
Display and Coordinates¶
KOI uses an IPS display with a resolution of 240x240.
The origin of the coordinates is at the top left corner with (x,y)=(0,0).
Real time camera feed and system notifications will be displayed on the monitor.
At the bottom left of the module, a microphone can be found. This microphone picks up sound in a range of approximately 50cm.
Micro USB Port¶
This MicroUSB port is used to power the KOI or connect to a computer.
PH2.0 4PIN Connector¶
This connector handles the serial communication between KOI and other micro controllers.
Beginners are advised to use an Armourbit to prevent incorrect connection.
Micro SD Card Slot¶
The SD card slot has an ejector mechanism, it supports cards up to 16GB. Images, sounds and classifier models will be saved to here.
The mono speaker is on the back of KOI.
LEGO Pin Connectors¶
Round slots on the back of KOI are compatible with LEGO Technic pins.
Pin Connector Spacing:
Length: 4 spaces between pins
Width: 3 spaces between pins
