TTP223 is a popular capacitive touch button chip that has been widely used in electronic projects. In this article we will take a closer look at its technical specifications, wiring diagrams and current prices. You’ll also learn about users’ opinions on this module and its most common applications. Read on to learn more about the TTP223 and get inspired for your own electronic projects.
Technical details of the TTP223 chip
The TTP223 chip is a component used in a variety of electronic projects that require the implementation of a tactile user interface. It is a single capacitive touch button that allows you to control devices without physical contact.
The TTP223 operates over a voltage range of 2V to 5.5V, making it compatible with most popular microcontrollers such as Arduino and Raspberry Pi. The standby current consumed by the chip is just 1.5 µA, which is important for battery-powered applications, increasing their operating time.
The module can operate in two modes: direct mode (TOG), where the state of the output changes with each touch, and interlock mode (AH), where the output activates with the first touch and deactivates with the next. The circuit’s response time to a touch is about 60 ms, ensuring a quick response to user commands.
In addition, the TTP223 has adjustable sensitivity to accommodate different outdoor conditions and thicknesses of insulation materials covering the touch panel. This flexibility makes it the designer’s choice for applications where precise and reliable touch interface performance is important.
The TTP223 offers not only high functionality and flexibility, but also easy integration and low power consumption, making it an excellent choice for many modern electronic projects.
TTP223 - wiring diagram
The TTP223 chip is a popular solution for projects requiring a simple touch interface. Here’s how to connect this module, allowing you to easily implement it in your project.
The basic wiring diagram of the TTP223 is extremely simple. The circuit has four pins: VCC, GND, SIG and OUT. VCC is the power pin, which should be connected to a voltage source between 2V and 5.5V. GND is ground, which is the negative connector of the power supply. The SIG pin is the signal output, which can be connected directly to any digital input of the microcontroller. OUT is an optional pin used for additional circuit configuration functions.
For most applications, it will be sufficient to connect the VCC and GND pins and SIG to the microcontroller. Once connected, the circuit is ready for operation and requires no additional programming. The state of the SIG pin changes from HIGH to LOW (or vice versa, depending on the settings) when the sensor is touched.
It is worth noting that the TTP223 chip can also be customized to meet specific user needs. For example, its sensitivity or configuration can be changed with additional components such as resistors or capacitors that modify its standard behavior.
Price of the TTP223 chip in Poland
The price of the TTP223 chip on the Polish electronics market is very attractive, making it a popular choice among amateurs and electronics professionals. The cost of a single TTP223 module usually ranges from PLN 1 to PLN 5, depending on the number of units purchased and the supplier.
Often you can meet with offers, where the layout is sold in the form of ready-made modules, which further facilitates its integration in projects. In the case of larger purchases, that is, when the number of modules exceeds several dozen pieces, the unit price can be significantly reduced.
In conclusion, the TTP223 is a cost-effective solution that offers high functionality at a low price, making it accessible to a wide range of users in Poland.
