Micro ATmega32U4 5V 16MHz Development Board

Description The Micro ATmega32U4 MU is a tiny microcontroller board based on the ATmega32U4 It has 20 digital input output pins 7 of which can be used as PWM outputs and 12 as analog inputs a crystal oscillator a micro USB connection an ICSP header and a reset button With a 16 MHz frequency and 5V operating voltage this board is similar to the Arduino Leonardo although the Micro ATmega32U4 MU is more compact 17 7848 26mm The board contains everything needed to support the microcontroller you just have to connect it to a computer and get started Its form factor enables it to be easily placed on the circuit board Like the Arduino Leonardo the Micro ATmega32U4 MU has built in USB connection eliminating the need for a converter This allows the Micro to appear to a connected computer as an HID device such as a keyboard or mouse in addition to a COM port The board is also able to perform other Arduino Leonardo functions Power The Micro ATmega32U4 MU can be powered via a USB connection Power Supply 5V The regulated power supply used to power the microcontroller and other components on the board This can come either from VIN via a voltage regulator or be supplied via USB or another regulated 5V supply 3V3 A 3 3V supply generated by the on board regulator Maximum current draw is 50mA GND Ground pins I O Pins Each of the 20 digital pins can be used as an input or output They operate at 5V Each pin can provide or receive a maximum of 40 mA and has an
