7 Inch G+G Capacitive Touch Panel with 10-Point Touch - CTP-T700GA-51

Ten Points Instead of Five: When It Actually Matters

Multi-touch point count is one of the few touch-panel specifications that is genuinely binary — either the controller tracks that many simultaneous contacts or it does not, and no amount of tuning adds capacity later. So it is worth being clear about what ten buys over five.

Atmel maXTouch: A Different Controller Family

The controller is an Atmel maXTouch 641T driving 16 × 28 channels — 448 sensing nodes. That is a deliberate choice, and it differs from the FocalTech and Ilitek parts used elsewhere in our range.

Why you might prefer it:

• Mature Linux support. The Atmel maXTouch family has a long-standing driver in the mainline kernel, so on an embedded Linux or Android platform it is largely a device-tree entry.
• Established in industrial and automotive. maXTouch parts are widely deployed in applications with long lifecycles and demanding environments, which tends to mean stable, well-understood behaviour.
• Configurable through a standard object protocol. Sensitivity, noise handling and gesture configuration are exposed in a structured way, which helps when you are tuning for glove operation or a thick cover.
• Strong noise handling. The 641T is designed around noisy environments — useful if your display, backlight or power stage is electrically busy.

On the other hand, if your team already has working FT5x06 code, choosing a panel with the same controller removes a variable. Both are reasonable; tell us your platform and we will say which is the easier path rather than steering you.
