Using this Circuit Playground TFT Gizmo is easy. First, attach the PCB to your Circuit Playground board using the provided 12 M3 screws. The M3 standoffs on the PCB will help with both mechanical and electrical connections. For the display, you can control the backlight according to your needs. If you want to add some lights or control a servo, use the two 3 - pin STEMMA connectors. To play audio, connect a small speaker to the Class D audio amplifier via the Molex PicoBlade connector. When using it with Arduino or CircuitPython, it works great with Circuit Playground Express or Bluefruit boards for fast performance. However, if you use it with the Circuit Playground Classic, be aware that it will be slow. As for maintenance, keep the PCB clean and dry. Avoid touching the display screen with dirty hands to prevent scratches or smudges. Also, store it in a cool and dry place when not in use.
