Introduction LinkNode R1 is a WiFi development board which is powered by the high integrated WiFi chip ESP-8266EX. Thanks for the contribution from open source community who have developed Arduino core for ESP8266, this let Aduino IDE program...

LinkNode R4 is a WiFi relay controller and it is powered by ESP-12f ESP8266 WiFi module which is compatible with Arduino programming. There are 4 relay channels and each channel allows you to control high-power devices (up to 10 A) via the on-board relay...

Introduction Bluetooth 4.0 BLE Gateway Shield is an addon that can turn pcDuino8 Uno into a Bluetooth 4.0 BLE gateway. It is using Nordic nRF51422 chipset and Arduino compatible. User have the flexibility to what serial ports (soft serial port or hard...

This is an adapter shield for Arduino that can allow eary connection of servo, sensors, communication modules, such as NRF24L01, Xbee.

So it turns out that your XBee based device would work even better as a BLE device… that probably means back to the drawing board, right? Well not anymore! Now you can swap in BLE functionality without a major hardware redesign!  Bluetooth 4...

Use this handy twins shield to install two Arduino shields on pcDuino/Arduino side by side. This is especially important when one Arduino shield doesn't expose the headers for stacking or the shield has components that are too high that preventing other...

ESP8266 offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor. When ESP8266 hosts the application, and when it is the...

Electronic paper, e-paper and electronic ink are display technologies which are designed to mimic the appearance of ordinary ink on paper. Unlike conventional backlit flat panel displays which emit light, electronic paper displays reflect light like...

This DFRobot 386AMP audio amplifier module uses the National Semiconductor LM386 audio power amplifier chip.  It has 20 voltage gain. In the 6V power supply, it's static power consumption of only 24mW, the module is suitable for battery-powered...

The Motor Pro Shield can independently drive four motors. It also has four interfaces for modules of linker kit, Analog: [A2 A3 VCC GND], Serial port: [D0, D1, V, GND], Digital IOs [D2, D4, V, GND], and [D5, D6, V, GND]. Moreover, it has interfaces...

RS485 is a standard communication port for field bus. Arduino only has a USB port and a TTL UART interface. In order to talk to a device that has RS485 bus, we can add a RS485 port to Arduino using this handy RS485 shield. Use this handy Arduino RS485...

RAMPS is short for  RepRap Arduino Mega Pololu Shield. It is designed to fit the entire electronics needed for a RepRap in one small package for low cost. RAMPS interfaces an Arduino Mega with its powerful platform and has plenty room for...
