The Motorino board is an extension-board to control and use up to 16 PWM-controlled 5V-Servo-motors. The included clock generator ensures a very precise PWM signal and a very precise positioning. The board has 2 inputs for voltage from 4.8 V to 6 V which can be used for up to 11 A. With this input, a perfect power supply is always guaranteed and even bigger projects are no problem. The supply runs directly over the Motorino which provides a connection for voltage, ground and control. With the build in capacitor, the voltage is buffered which prevents a sudden voltage-drop at a high load. But there is also the possibility to connect another capacitor. The control and the programing can be done, as usual, with the Arduino. Manuals and code examples allows a quick introduction for beginners. Specifications Special features 16 Channels, own clock generator Input 1 Coaxial power connector 5.5 / 2.1 mm, 4.8-6 V / 5 A max Input 2 Screw-terminal, 4.8-6 V / 6 A max Communication 16 x PWM Compatible with Arduino Uno, Mega and may more microcontroller with Arduino compatible pinout Dimensions 69 x 24 x 56 mm Included Board, Manual, Retail package

The ESP8266 is an impressive, low cost WiFi module suitable for adding WiFi functionality to an existing microcontroller project via a UART serial connection. The module can even be reprogrammed to act as a standalone WiFi connected device – just add power! 802.11 b/g/n protocol Wi-Fi Direct (P2P), soft-AP Integrated TCP/IP protocol stack This module is a self-contained SOC (System On a Chip) that doesn’t necessarily need a microcontroller to manipulate inputs and outputs as you would normally do with an Arduino, for example, because the ESP-01 acts as a small computer. Thus, you can give a microcontroller internet access like the Wi-Fi shield does to the Arduino, or you can simply program the ESP8266 to not only have access to a Wi-Fi network, but to act as a microcontroller as well, which makes the ESP8266 very versatile.
