Ethernet W5100 Shield for Arduino The Arduino Ethernet Shield enables an Arduino board to connect to the internet using the Wiznet W5100 ethernet chip. This chip provides a network (IP) stack that supports both TCP and UDP protocols. The Ethernet W5100 Shield Network Expansion Board, which comes with a micro SD card slot, supports up to four socket connections at once. To connect to the internet using the Arduino shield , utilize the Ethernet library to write sketches. The shield connects to an Arduino board using long wire-wrap headers that pass through the shield. This keeps the pin layout intact and allows for stacking of another shield on top. The most recent revision of the board exposes the 1.0 pinout on the Arduino UNO board's rev 3. This Ethernet Shield facilitates a quick connection of the UNO R3 board to the internet. To get started, plug the module onto the Arduino board , connect it to the network using an RJ45 cable (not included), and follow a few simple instructions to control your world through the internet. Additionally, it allows the connection of your Arduino UNO 328 or MEGA 2650 1280 to a network or the internet while storing or retrieving files on a Micro SD Card. The Ethernet Shield features a standard RJ-45 connection with an integrated line transformer and Power over Ethernet enabled. It also has an onboard micro-SD card slot, which stores files that are accessible over the network. The shield is compatible with Uno and Mega boards, utilizing the Ethernet library. The onboard microSD card reader is accessible via the SD Library, with SS located on Pin 4 when working with this library. Note that the original revision of the shield had a full-size SD card slot that is no longer supported. Lastly, the shield includes a reset controller, ensuring that the W5100 Ethernet module properly resets upon power-up. In previous revisions of the shield, compatibility with the Mega board required a manual reset after power-up.

IRF520 MOSFET Driver Module for Arduino/ Raspberry Pi IRF520 MOSFET Driver Module for Arduino/ Raspberry Pi is a breakout board for the IFR520 MOSFET transistor. The module is designed to switch heavy DC loads from a single digital pin of your microcontroller. Here is a simple breakout board for the IRF520 Mosfet. Easy hookup to your Arduino or another 3-5v microcontroller. Pulse current through a PWM pin, and use this to control a pump, LED, or other DC device at up to 24v, and ~5A. The main purpose of this IRF520 MOSFET Driver Module Board compatible with Arduino is to provide a low-cost way to drive a DC motor for robotics applications, but the module can be used to control most high current DC loads. Screw terminals are provided to interface with your load an external power source. An LED indicator provides a visual indication of when your load is being switched. How to use PWM Adjustment MOS Drive Board? The simplest way of explaining how this little board works is as below: You connect the power for the device you want to control the Vin and GND. You connect your device to the V+ and V- screw terminals. When the SIG line is HIGH, a little LED lights up, and the GND is ‘connected’ to the V-. When the SIG line is LOW, the LED turns off, and the GND becomes ‘disconnected’ to the V-. The V+ and Vin are continuously connected. You can power this device from your Arduino, VCC goes to the 5V connection and GND to the GND pin on your Arduino. Note : Heat sinks need to be installed for loads above 1A .
