Bi-directional Logic Level Converter 4-channel by I2C BSS138

BTBee Pro is a Bluetooth serial port module that can be compatible with shields that have XBee socket.

Now, it's time to add a more sophisticated interactive way to your project. The DFRobot touch kit comes with three types of touch sensors . A ipod styple touch wheel, a touch touch screen that supports backlit and a grid touch pad that can recognize something unique.

Carbon monoxide detector with alarm - orno

This version of the Ethernet Shield is not only compatible with Mega 1280 and 2560, but also provides a Micro SD card slot for read / write

This module is based on the popular L298N H Bridge DC Motor Driver . The circuit will allow you to easily and independently control two motors up to 2A each in both directions.

This DTMF Shield is a Dual-tone multi-frequency signaling module decoder for Arduino With it's audio connector you can decode the crazy funny noises common phones make.

When you assign a high level to the module pin, the electro magnet can suck magnetically conductive objects. Otherwise, it will release the object.

An electro magnet is a type of magnet in which the magnetic field is produced by electric current. An electric current flowing in a wire creates a magnetic field around the wire, due to the Ampere Law. To focus the magnetic field on an electro magnet, the wire is wound into a coil with many twists of wire side by side. The Magnetic Field of All Twists of the Wire passes through the Coil Center, creating a Strong Magnetic Field there.

It's Easy to Use to Learn the Electro Magnet Principle.

This is the FeatherWing Adalogger: it adds a real-time clock with battery and micro SD card storage to any Feather mainboard. Using the Headers, you can connect a FeatherWing to the top of your board and let the board fly!

Gravity: IO Expansion Shield for Arduino V7.1

The HC-12 433MHz Transceiver is a wireless communication Module, which is based on the RF SI4463 chip, has a built-in microcontroller and can be configured by AT commands, the maximum output power is 100mW (20dBm) and the receiver sensitivity differs from: 117dBm to -100dBm, depending on the transmission speed. Accepts 3.2V - 5.5V and can be used with 3.3V and 5V UART voltage devices.

Can be used to monitor the heart rate of the patient and athlete. The result can be displayed on a screen via the serial port and can be saved for analysis.

This is the Infrared Proximity Sensor made by Sharp.

WiDo is a WIFI IoT Node development board compatible with Arduino.

Joystick red by Joy-D.

The Kit Set of Torix Connectors is widely used in building wiring. By selecting the best insulation material, it is durable, corrosion free, anti-aging, pressure 4kv and against electric shock. It breaks the disadvantage of the traditional wiring method which is problematic in wiring, easy to leak, and easy to corrode.

LCD Gráfico 128x64 STN LED Backlight

This LED Matrix 24 × 8 display is specially designed for the FireBeetle series. It supports low power mode and scroll display. With HT1632C high-performance LED driver chip , each led has an independent register, which facilitates separate driving. Integrates a 256KHz RC clock, only 5uA in low power mode, supports 16-scale PWM brightness adjustment. This product also works with another Arduino microcontroller like Arduino UNO (same as DFRduino UNO).
