Specification:

Features:

🖐️ 1. Capacitive Touch Detection

• The gold-plated sensor pad responds to the capacitance change when a human finger approaches.

• No mechanical movement = silent, wear-free switching.

• Highly sensitive, and can detect touch through:

  • Plastic enclosures

  • Acrylic sheets

  • Thin glass (up to 3mm)

⚡ 2. Digital Output (Active High)

• On touch, the output pin goes HIGH (logic 1).

• When released, it returns to LOW (logic 0).

• Ideal for triggering microcontroller interrupts, toggling LEDs, or activating relays.

🔧 3. Configurable Modes (Toggle vs. Momentary)

• By default, operates in momentary mode (touch = ON, release = OFF).

• You can change to toggle mode (first touch = ON, next touch = OFF) by bridging a solder jumper on the back:

  • TP (toggle pin) for toggle/monostable configuration.

  • AHLB jumper adjusts output state (active high or low).

  • I/O pin pull-up/pull-down configurations to change behavior.

🔋 4. Low Power Consumption

• In standby, current draw is in the microamp range (~2µA).

• Suitable for battery-powered projects like wearables, portable gadgets, or remote controls.

🔄 5. Fast Response Time

• Reaction time as low as 60ms in fast mode.

• Maintains responsiveness even with multiple touches in rapid succession.

🧩 6. Microcontroller Friendly

• Logic levels are 3.3V and 5V compatible.

• Works seamlessly with:

  • (UNO, Nano, Mega)

  • ESP32 / ESP8266

  • STM32

  • Pi

  • ATtiny, PIC, and other 8-bit MCUs

📦 7. Compact PCB Design

• Measures approx. 24mm x 24mm x 7mm

• Easy to embed in tight enclosures or project boxes

• 2 x M2 mounting holes for secure installation

💡 8. Onboard Status LED

• Bright red LED turns ON when touch is detected.

• Useful for debugging or as a visual indicator in the final project.

📌 9. Stable & Robust Performance

• Works reliably across different environmental conditions.

• Good resistance to electromagnetic interference.

• No false triggers or floating states when used with proper power filtering (capacitor recommended).

Description:

The TTP223 1-Channel Capacitive Touch Sensor Module is an advanced touch-based input device designed to replace traditional mechanical buttons with a modern, more intuitive touch-sensitive solution. Based on the TTP223 touch-sensing IC, this module enables you to detect touch input with great precision and minimal latency, ideal for projects that demand sleek, low-profile, and reliable human-machine interfacing.

This module is specifically engineered in a striking red PCB with a large gold-plated touchpad, offering both a visual appeal and enhanced sensitivity. The capacitive pad detects the small change in capacitance when a human finger approaches, allowing for non-contact or light-touch activation. This makes it ideal for use in harsh environments, sealed enclosures, or in projects where physical buttons would wear out or become unreliable over time.

The TTP223 module outputs a digital HIGH signal when touched, making it compatible with virtually all microcontrollers such as ESP32, STM32, Pi, and many others. It features single-pin digital output, allowing for simple and fast integration into any electronics project.

Designed for versatility, the module offers configurable settings via solder jumpers on the rear side. These jumpers allow users to switch between momentary and toggle output modes and change the logic level output to suit different applications. In its default configuration, it acts like a momentary push-button: it outputs HIGH while the sensor is being touched and returns LOW when the touch is released.

Thanks to its ultra-low power consumption, the TTP223 sensor is highly suited for battery-powered devices. Its low idle current (<2µA) ensures minimal drain when not in use, making it ideal for smart gadgets, portable systems, and embedded electronics. The integrated onboard status LED provides a convenient way to monitor the touch detection status visually, aiding in rapid development and troubleshooting.

Whether you're building a touch-sensitive lamp, interactive control panel, or embedded device requiring a sleek user interface, the TTP223 Capacitive Touch Sensor Module offers a durable, responsive, and elegant input mechanism in a small and affordable form factor.
