Introduction
The Button Bolt-on for the ESP32-X2 development board features a TS-1002S-04326C tactile switch and WS2812B 2020 RGB LEDs. The TS-1002S-04326C is a compact, low-profile push button from XUNPU, designed for reliable on/off operation in space-constrained applications. Its 6x6 mm size and 4.3 mm actuator height make it easy to use while minimizing accidental activations. This switch is widely used in consumer electronics and industrial control panels.The WS2812B 2020 RGB LED, known for its minimal 2x2 mm size, offers individually addressable lighting with vibrant colors, operated with a 5V power supply. It is perfect for space-sensitive applications like wearables and mobile devices.Each tactile switch on the Button Bolt-on board is paired with two WS2812B 2020 RGB LEDs, providing a total of four switches and eight LEDs. This combination enhances the interactivity and visual feedback for user inputs.
Features
Following are the features of 2 main components TS-1002S-04326C and WS2812 (2020 package) that are used in the Button bolt-on board.<be>

Hardware, Pin Description, Connections
WS2812 RGB LED Hardware
The hardware of the WS2812 LED module is as follows:
WS2812 RGB LED Pin Description
Pin Description of the WS2812B LED with 2020 package is as follows:
_(1).png)
| Symbol | Description |
|---|---|
| DO | Data Output (DOUT): Outputs the control data signal to the next device in the chain. Used for cascading multiple modules or LEDs to create a series connection. Connect to the DI of the next module in a daisy-chain setup. |
| GND | Ground: Connect to the ground (0V) of the power supply. Ensures stable operation by providing a common reference point for the circuit. |
| DIN | Data Input (DIN): Receives the control data signal from the microcontroller or the previous device in the chain. Used for controlling the LED or module by sending data signals through this input pin. |
| VDD | Power Supply: Connect to a 5V DC power source to power the module. Ensure a stable and sufficient power source to support the device’s operation. |
