DFRobot Gravity 6×6 Flexible Array Tactile Pressure Sensor (UART Matrix FSR)

The sensor communicates via a UART (Universal Asynchronous Receiver-Transmitter) interface. This provides a simple digital serial connection, typically using TX and RX pins, which reduces wiring complexity and is supported by most microcontrollers. The UART protocol also allows for daisy-chaining multiple sensor arrays on a single bus.

Yes, the sensor is constructed on a Flexible Printed Circuit (FPC), making it thin and pliable. This design allows it to conform to curved surfaces such as robotic finger joints, glove fingertips, or other non-planar mounting points without compromising the functionality of the individual 36 sensing points.

The trigger force for each of the 36 sensing points is 20 grams. This provides high sensitivity for detecting light touches. The full measurement range extends from this 20g threshold up to 5 kilograms of force per individual point, offering a wide dynamic range for various applications.

Yes, the sensor is designed for broad compatibility. It works with 5V logic microcontrollers like many Arduino boards, as well as 3.3V logic systems such as the ESP32 and Raspberry Pi. For 3.3V systems, ensure logic level compatibility if connecting the UART lines directly.

The sensor is rated for over 1,000,000 actuation cycles when tested with a 1kg force. This high durability is achieved through robust materials and construction, making it suitable for long-term use in repetitive applications like robotic gripping, interactive interfaces, and wearable devices.
