4 H-Bridges: Per bridge provides 0.6A (1.2A peak current) with thermal protection, can run motors on 4.5V to 36V DC pull down resistors keep motors disabled during power-up Up to 4 bi-directional DC motors with individual 8-bit speed selection up to 2 stepper motors (unipolar or bipolar) with single coil, double coil or interleaved stepping
Material: FR4 + Electronic components The Arduino Ethernet W5100 network expansion module allows the Arduino to be a simple Web server Supports reading and writing mini SD / TF card With Micro SD card slot, supports SD card up to 2GB, supports MEGA, Uno
Xbee radios are an awesome way to add wireless capability to your Arduino project and now it’s even easier with the XBee Shield. . The shield form-factor mates directly with any dev board that has an Arduino standard footprint and equips it with wireless communication capabilities using the popular XBee module.
The W5100 Ethernet Module is a full-featured, single-chip. This Ethernet controller is designed for embedded applications; where ease of integration, stability, performance, area and system cost control are requires.
Arduino UNO uses ATMEGA328P-PU microcontroller and this controller comes pre-loaded with a Arduino UNO bootloader. Basically bootloader is a little piece of code that allows you to program the flash memory of the Arduino’s atmega328p via serial or USB instead of using an ICSP programmer.
