Arduino Micro


The Arduino Micro is a microcontroller board based on the ATmega32u4, developed in conjunction with Adafruit. It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHzcrystal oscillator, a micro USB connection, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a micro USB cable to get started. It has a form factor that enables it to be easily placed on a breadboard.
The Micro is similar to the Arduino Leonardo in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Micro to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port.

Arduino Esplora


The Arduino Esplora is a microcontroller board derived from the Arduino Leonardo. The Esplora differs from all preceding boards in that it provides a number of built-in, ready-to-use setof onboard sensors for interaction.
The Esplora has onboard sound and light output interfaces. It alos has the potential to expand its capabilities with two Tinkerkit input and output connectors, and a socket for a color TFT LCD screen.
Like the Leonardo board, the Esplora uses an Atmega32U4 AVR microcontroller with 16 MHz crystal oscillator and a micro USB connection capable of acting as a USB client device, like a mouse or a keyboard.
In the upper left corner of the board there is a reset pushbutton, that you can use to restart the board. There are four status LEDS :
  • ON [green] indicates whether the board is receiving power supply
  • L [yellow] connected directly to the microcontroller, accessible through pin 13
  • RX and TX [yellow] indicates the data being transmitted or received over the USB communication
The board contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable to get started.
The Esplora has built-in USB communication; it can appear to a connected computer as a mouse or keyboard, in addition to a virtual (CDC) serial / COM port.

LilyPad Arduino USB


The LilyPad Arduino USB is a microcontroller board based on the ATmega32u4. It has 9 digital input/output pins (of which 4 can be used as PWM outputs and 4 as analog inputs), an 8 MHz resonator, a micro USB connection, a JST connector for a 3.7V LiPo battery, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a battery to get started.
The LilyPad Arduino USB differs from previous LilyPad boards in that the ATmega32u4 has built-in USB communication, eliminating the need for a separate USB-to-serial adapter. This allows the LilyPad Arduino USB to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port.

MC33887APVW 5.0 A H-Bridge with Load Current Feedback



The 33887 is a monolithic H-Bridge Power IC with a load current  feedback feature making it ideal for closed-loop DC motor control.The IC incorporates internal control logic, charge pump, gate drive,  and low RDS(ON) MOSFET output circuitry. The 33887 is able to control inductive loads with continuous DC load currents up to 5.0 A,  and with peak current active limiting between 5.2 A and 7.8 A. Output loads can be pulse width modulated (PWM-ed) at frequencies up to 10 kHz. The load current feedback feature provides a proportional (1/  375th of the load current) constant-current output suitable for  monitoring by a microcontroller’s A/D input. This feature facilitates the design of closed-loop torque/speed control as well as open load detection.


A Fault Status output pin reports undervoltage, short circuit, and  overtemperature conditions. Two independent inputs provide polarity control of two half-bridge totem-pole outputs. Two disable inputs 
 force the H-Bridge outputs to tri-state (exhibit high-impedance). 

The 33887 is parametrically specified over a temperature range of -40°C ≤ TA ≤ 125°C and a voltage range of 5.0 V ≤ V+ ≤ 28 V.  Operation with voltages up to 40 V with derating of the specifications. 

Features 

  • Fully specified operation 5.0 V to 28 V  
  • Limited operation with reduced performance up to 40 V   
  • 120 mΩ RDS(ON) Typical H-Bridge MOSFETs  
  • TTL/CMOS Compatible Inputs 
  • PWM Frequencies up to 10 kHz
  • Active Current Limiting (Regulation)
  • Fault Status Reporting
  • Sleep Mode with Current Draw ≤50 μA (Inputs Floating or Set to Match Default Logic States)
