Product Information
Product Name: KTD2061 EVAL Kit
Description: 36-Channel RGB LED Drivers with I2C Control
Product Usage Instructions
- Using the StemmaQT/Qwiic I2C wiring harness, connect the EVAL Kit PCB to the QT Py PCB. Make sure to insert the StemmaQT/Qwiic connectors correctly to avoid damage.
- Connect the USB cable to the QT Py RP2040 PCB.
- Connect the other end of the USB cable to a USB 5V/1A power source (user-supplied). You can use an AC wall adapter, battery power bank, or an available USB port from a computer.
- When power is applied, the demo software will execute three test patterns that are already stored within the product.
- To customize the behavior of the EVAL Kit, follow these steps:
- Download the CircuitPython library and install it on your computer.
- Open the CircuitPython text file code.py with a software editor. Adafruit recommends using the freeware Mu editor, which is optimized for CircuitPython.
- Edit the code in code.py to make the desired changes.
- Save the changes to the QT Py RP2040. After saving, the code will automatically recompile and execute.
- The code.py file is already replicated as KTD2061_demo_code.txt on the QT Py RP2040.

Quick Start Procedures and Additional Resources
- Using the StemmaQT/Qwiic I2C wiring harness, connect the EVAL Kit PCB to the QT Py PCB. To avoid damage within the connectors, do not insert the StemmaQT/Qwiic connectors upside down.
- Connect the USB cable to the QT Py RP2040 PCB.
- Connect the other end of the USB cable to a USB 5V/1A power source (user-supplied). You may use an AC wall adapter, battery power bank, or an available USB port from a computer.
- When power is applied, the demo software first executes 3 test patterns:
- a. All 12 RGB modules turn very dim white for 1 second, then bright white for 5 seconds.
- b. Each RGB takes its turn showing blue, one at a time, and then repeats with green.
- c. The 12 RGBs show a multi-color palette for 5 seconds. Three of them are dim white on purpose.
- After the test patterns, the demo loops an 8-minute demonstration endlessly until power is removed.
- When desired, remove power by pulling the AC wall adapter from the AC outlet, or by disconnecting the USB cable from the USB power source.
- Optionally, to read or modify the demo software, connect the USB cable to a computer.
- a. The QT Py RP2040 connects as an 8MB USB flash drive. The software and collateral documents are stored within.
- b. Open the CircuitPython text file code.py with a software editor. Adafruit recommends the freeware Mu editor, which is optimized for CircuitPython.
- c. When editing code.py, save changes to the QT Py RP2040. After saving, the code will recompile and execute automatically.
- d. The code.py file is already replicated as KTD2061_demo_code.txt on the QT Py RP2040.
