Customer Questions & Answers

What are the exact dimensions, weight and included contents when purchasing this module?

The module measures 65 mm x 50 mm and typically weighs around 20 g. In a standard purchase, only the assembled board is included; cables or brackets are not usually supplied, so you should allow for these extras depending on the installation.

What are the best practices for installing this module and avoiding unwanted capacitive interference?

It is recommended to mount the TTP229 on non-metallic surfaces and keep at least 2 mm clearance from conductive objects. It is crucial to avoid long unshielded cables and to use a common GND. In industrial environments, additional enclosure or filtering may be required.

What kinds of sensitivity issues or false touches can occur, and how are they resolved?

The module’s sensitivity can be affected by humidity, high static electricity or proximity to conductive objects. To solve this, keep the surface dry, move the module away from RF sources, and adjust sensitivity in hardware or software if the system design allows it.

What voltage does the TTP229 module work with?

The TTP229 module works with an operating voltage between 2.4V and 5.5V.

How many touch keys does the TTP229 module have?

The module has 16 integrated capacitive touch keys.

Is the TTP229 compatible with Arduino?

Yes, the module is designed to be compatible with Arduino boards and makes integration into projects easier.

What is the module's current consumption?

The current consumption is very low, approximately 2.5 µA.

What type of interface does the module use to communicate?

It uses a serial interface with 8 digital outputs for data communication.
