kinetic technologies KTD2061 36 Channel RGB LED Drivers

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.
