Product Information
The KT1622 EVAL Kit is a fully assembled PCB designed for low voltage 16-bit I2C-bus I/O expansion. It features the MCP2221A Board, which is a general- purpose USB to GPIO ADC I2C interface board. The kit also includes a Stemma QT / Qwiic JST SH 4-pin Cable (100mm long) and comes in an anti-static bag. The kit is accompanied by a printed 1-page (A4 or US Letter) Quick Start Guide and is packaged in an EVAL Kit box.

Product Usage Instructions
- Connect the Stemma QT 4-wire cable (GND, 3V3, SDA, SCL) to the KTS1622 evaluation board connector CN1, as shown in the Typical Test Setup Figure below.
- Connect the other end of the Stemma QT cable to the MCP2221A USB to I2C interface board.
- Connect the MCP2221A board to a computer via the USB type-C cable.
- Once the evaluation board is connected to the computer via the MCP2221A interface board, check if the KTS1622 evaluation board green LED D1 is turned on. This indicates that the board is powered from the computer. The on-board VIN supply voltage should be around 3.3V. No external power supply is required.
- Install the GUI software by following these steps:
- Download the GUI software from the EVAL Kit Page at https://www.kinet-ic.com/kts1622euaa-mmev01/.
- After downloading, install the software. Once installed, the interface will appear with the status message “USB Device Attached” at the bottom left side of the window.
- If the displayed message is “USB Device Detached,” ensure that the computer is properly connected to the board.
Note : Refer to the provided Quick Start Guide for any additional instructions or troubleshooting.
