This 4-digit 7-segment shield has 5 buttons that can be used as menu selection buttons or control buttons, using I2C to conduct the digital call.

Imagine a Arduino Shield that can be configured to be an LCD, GPS, Wifi, or any Shield you can imagine!

Arduino is a huge ecosystem, so if there is a way to adapt the Raspberry Pi interface to Arduino pinning, you can create fantastic designs using the best of both worlds. This Adapter Board was created just for this.

An ESP8266 Wifi Shield for Arduino.

Now the ESP8266 D1 Mini v3 is no longer alone! If you like WiFi communication, especially with ESP8266 chips, you can't miss this kit that includes several modules such as sensors, button, LED, Display, Relay, protoboard, among others. And you couldn't miss the respective ESP8266 D1 Mini v3 to be able to program in an Arduino environment and develop your wireless and IoT projects.

ITDB031 is a serial port BLE Module. It is based on TI's CC2541 BLE chip. With it, you can transfer data wirelessly and do remote control. It supports central and peripheral modes. And it supports remote control for the other side that is connected. You can also support custom commands when you combine it with other devices. BLE Bee is compatible with XBee. You can simply connect it to XBee.

Note: The serial interface is 3.3V, not the typical 5V, as with many Arduino boards.

The BLE shield has the function of adapting low-power Bluetooth as a serial port , which are specifically designed for Arduino boards and compatible boards, simple to use, simply connect and a ready is ready to be used.

This board is the combination of 3 extremely interesting products: a ESP32 Module with WiFi and Bluetooth, a oLED Display and a battery charging and charging system Lithium-Ion 18650.

Gravity: IO Expansion Shield for Arduino V7.1

This Module is a Rotary Incremental Encoder. It encodes the shaft rotation signal and outputs the signal by electronic pulse. The Grove –Encoder is a module of the Grove series and has a standard Grove interface. When you need to add a knob to your project, for example a volume knob for a speaker, a selection panel or a digital input, this should be your first choice.
