1. Use with Robotbit EDU
Use the cable included to connect KOI to Robotbit.
Connect KOI 2 to the serial port of the Robotbit EDU as shown in the illustration.
As Robotbit EDU uses P2 and P12 for its serial port, you will need to select the appropiate pins in the MakeCode program.
2. Use with Robotbit 2.2
Use the cable included to connect KOI to Robotbit.
Refers to the following illustration for correct wiring.
Black - GND
Red - 5V
Yellow - P2 (TX)
Blue - P12 (RX)
Do not connect Red to Ground and Black to 5V!!!
Ensure the connection is correct and switch the power on.
3. Use with Armourbit
It is easier to connect to an Armourbit because they both use PH2.0 connectors.
When using KOI with an Armourbit, KOI needs an extra 5V power source.
Using the USB port on the battery box, 5V power can be supplied to KOI. (See figure below)
Use the corresponding programming block and select the correct port.(Default Port 1)
