Digital Display for HC-SR04 Ultrasonic Distance Measurement Control Board adopts 8 bit MCU as the main control chip; it can be applied in distance measurement, testing HC-SR04 ultrasonic module performance. And it supports serial port display and digital tube displa
Transparent Acrylic Case Enclosure Glossy Box For Mega 2560 R3 is made by high grade acrylic, which provides excellent protection. This is unique design provides easy connection to other components. The dimension of enclosure box is the same as original MEGA2560 R3.
Note : This product only includes the case, there is no Mega2560 R3 board inside of the package
The Leonardo is an open source precise microcontroller board based on the ATmega32U4 SMD chip. It has 23 digital input/output pins (of which 7 can be used as PWM outputs and 12 can be used as analog inputs), a 16 MHz crystal, a USB connection, a power jack, an in-circuit system programming (ICSP) header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer (or appropriate wall power adapter) with a Micro USB cable or power it with a AC-to-DC adapter or battery to get started.
The Leonardo differs from all preceding boards in that the user-programmable ATmega32U4 AVR microcontroller has built-in USB functionality, eliminating the need for a secondary processor. This makes the Leonardo more versatile: in addition to supporting a virtual (CDC) serial/COM port interface, it can appear to a connected computer as a mouse and keyboard.
The LilyPad 328 ATmega328P Main Board 16M is an Arduino-program micro-controller design to be easily integrated into e-textiles and wearable projects. It offers the same functionality you find in other Arduino boards, in a lightweight, round package design to minimize snagging and profile. With wide tabs that can be sewn down and connect with conductive thread.
The LilyPad Arduino consists of an ATmega328 with the Arduino bootloader and a minimum number of external components to keep it as small (and as simple) as possible.
This board will run from 2V to 5V and offers large pin-out holes that make it easy to sew and connect. Each of these pins, with the exception of (+) and (-), can control an attached input or output device (like a light, motor, or switch).
Each LilyPad was creatively designed to have large connecting pads to allow them to be sewn into clothing. Various input, output, power, and sensor boards are available. They’re even washable!
NANO Version 3 is the open source smallest Embedded Development board based on Atmega328 SMD Package Microcontroller. It is a Surface mount Breadboard Friendly board integrated with Mini USB Port. DC Power Jack is not available on this Board, so power can be given through Mini USB Cable. It automatically sense and switch to the higher potential source of power, there is no need for the power select jumper.
