DKARDU 2.5V~5.25V BlackBerry Trackball Breakout - Review

If you are looking to incorporate a trackball into your DIY electronics project, the DKARDU 2.5V~5.25V BlackBerry Trackball Breakout Board Module might be just what you need. This module, made by the DKARDU brand, comes with a replacement trackball, ring, and Dupont cable, making it an all-in-one solution for your trackball needs.

First, let's touch on the switch included in the module. The SMD momentary switch, located under the trackball, provides a select switch, and pressing the switch will pull the BTN line low. This switch makes it easy to navigate and select options on your project, making it a versatile addition.

The working voltage range for the module is 2.5~5.25V, and the PCB size is 22*28mm, making it small enough to fit into tight spaces and compatible with a variety of power sources. This module is also made up of original electronic components, so you can be confident in its quality and longevity.

The trackball itself is designed with four spindles, each with a tiny circular magnet that is paired with an SMD hall effect sensor. These sensors measure up, down, left, and right movements of the trackball, providing precise and accurate control. With just a slight roll, multiple high/low transitions are created on the four axis pins, making it easy to incorporate into any microcontroller.

So why the 3.5-star rating? While this module boasts impressive features, some customers have noted that the Dupont cable included is too short and the ring is flimsy. However, these issues can be easily resolved with the purchase of a longer cable and a sturdier ring.

Overall, the DKARDU 2.5V~5.25V BlackBerry Trackball Breakout Board Module provides a convenient and easy-to-use trackball solution for DIY electronics enthusiasts. With precise control and a versatile design, this module can be a valuable addition to any project.
