Capacitive Touch Sensor TTP223B

grabcad

This is a custom model of the TTP223B capacitative touch sensor, created since there weren't any available models on GrabCad to use. I deliberately kept my header pins simple, opting for an approximate representation of their space requirements rather than detailed designs. Since I didn't have access to a physical model, my measurements were based on a high-quality picture of the TTP223B from HiLetgo's Amazon listing. They confirmed that the holes are indeed M2 size, and I relied heavily on this image's precise dimensions as a reference for scaling my model accurately.
