"Touch Sensation Device Development / Tactile Module 'hapStak'" is a module that combines a vibration actuator and driving circuit, making it easy to reproduce tactile sensations through vibration.
It adopts the latest actuator "FOSTER ACOUSTICHAPTIC®" developed by Foster Electric, which features three outstanding qualities not found in conventional modules: **"wide-area vibration," "low latency," and "quietness."** This versatile actuator produces various tactile sensations.
To support advanced vibration haptic implementation across various devices, two types are available:
- **Digital Version:** Equipped with I2S connection sockets compatible with microcontroller boards such as Arduino MKRZero and M5Stack Atom, suitable for controlling via digital signals.- **Analog Version:** Easily generates vibrations from audio signals, allowing users to experience tactile sensations through simple sound inputs.
This product enables the creation of devices such as vibration controllers aimed at enhancing game and VR entertainment experiences. It aims to be a new standard in the development of tactile devices that "create sensations that should not exist."
### Examples of Product Applications- Implementation in game controllers- Handheld devices for VR experiences- Use in exhibition amusements- Demonstrations at trade shows- Educational materials for engineering and information science courses

### Compatibility & ControlSupports I2S communication, enabling control from various microcontroller boards.※ Digital version
*Note:* The appearance and material of the case may vary depending on the shipment period.
To facilitate control with small microcontroller boards, the device is equipped with an I2S interface compatible with Arduino MKRZero and M5Stack Atom series.It can directly play audio data from the microcontroller to generate vibrations.
Power can be supplied from the microcontroller, resulting in a clean cable setup, and it can operate on power from common USB mobile batteries.
Users can create compact, handheld devices utilizing the microcontroller’s network functions and other features.A wooden, assembled case is included.
This allows for quick creation of simple devices.
### Analog Version: Easily Reproduce High-Quality Tactile Experiences Using Only Audio Signals
Using basic audio signals such as MP3s, astonishing tactile sensations can be achieved.
The module accurately reproduces tactile sensations from familiar sounds like the impact of a bat or keyboard typing.
### Caution!**Digital Version**Using this product requires a separately sold microcontroller board, a PC for programming, and basic knowledge of these.The M5Stack Atom terminals and Arduino MKRZero terminals are mutually exclusive and cannot be connected simultaneously.
**Analog Version**This product is a module combining an actuator and driving circuit.You must provide your own device for playing sound sources.Power supply from a USB power terminal and a battery box are mutually exclusive and cannot be used at the same time.
