9 in 1 Multifunction Expansion Board

Multi-Sensor All-in-One Shield: Integrates 9 distinct electronic hardware modules on a single expansion shield, eliminating messy jumper wiring during prototyping and learning sessions.

Onboard Environmental Sensors: Includes an onboard DHT11 temperature and humidity sensor along with an LM35 linear analog temperature sensor interface for immediate climate telemetry.

Built-In User Interface & Controls: Outfitted with 2 tactile push-buttons, a precision rotary potentiometer, a 2-channel digital LED indicator set, and an active buzzer for audio feedback.

Integrated Wireless & Infrared Interfaces: Features an integrated IR receiver head for remote control projects and dedicated pin header ports for adding Bluetooth (HC-05/06) or APC220 wireless modules.

Direct UNO/Mega Compatibility: Standard Arduino header pinout snaps directly onto Arduino UNO, Mega2560, and compatible microcontroller baseboards.

Board Material: Heavy-duty FR-4 glass-epoxy PCB with black solder mask, gold-plated header pads, and pre-soldered surface-mount components.

Technical Specifications:

Form Factor: Arduino UNO R3 Shield Layout.

Operating Voltage: 5.0V DC.

Onboard Peripherals: DHT11 Sensor, LM35 Interface, RGB/Dual LED, Active Buzzer, IR Receiver, Potentiometer, 2x Push Buttons.

Expansion Ports: I2C Header, Serial/Bluetooth Header, Digital/Analog GPIO Headers.

Board Color: Black PCB with Multi-Color Components.

Usage Advice: Align shield pins carefully with the Arduino UNO headers before pressing down; use standard Arduino libraries for DHT11 and IR receiver functions.

Maintenance: Store in an antistatic bag when disconnected, and keep the board clean of metallic dust, flux, and liquids.

Essential All-in-One Starter Expansion Shield: Position as the ultimate all-in-one educational module for STEM students, electronics courses, and rapid prototyping without breadboard clutter.

Highlight 9-in-1 Versatility: Emphasize how a single shield allows users to practice GPIO inputs, analog reading, environmental sensing, PWM dimming, wireless telemetry, and audio generation.

Recommended Cross-Sell Add-ons: Pair with DHT11 Temperature & Humidity Sensor Module, LM35D Analog Temperature Sensor Module, ESP8266 D1 mini + DHT11 Shield, and ESD antistatic mat 50x40CM PCB Welding Mat.
