Description

ARDUINO A000053 Development Board, Arduino Micro, ATmega32U4 MCU, 20 3.3V I/O, 12 Analogue Inputs, ISCP HeaderThe A000053 is a Arduino Micro development board based on the ATmega32u4 microcontroller. The ATmega32u4 is a 8bit AVR RISC based microcontroller featuring 32KB flash memory, 2. 5KB SRAM, 1KB EEPROM, USB 2. 0 full speed low speed device, 10bit A to D converter and JTAG interface for on chip debug.

The A000053 is a Arduino Micro development board based on the ATmega32u4 microcontroller. The ATmega32u4 is a 8bit AVR RISC based microcontroller featuring 32KB flash memory, 2.5KB SRAM, 1KB EEPROM, USB 2.0 full speed/low speed device, 10bit A to D converter and JTAG interface for on chip debug. The board 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. It also has other implications for the behaviour of the board. The Arduino Micro can be powered via the micro USB connection or with an external power supply. The power source is selected automatically.
  • 16MHz crystal oscillator

Order 1 size larger.
Size: X-Large, Color: Blue White Plaid
Nice shirt. The size is not accurate by any stretch of the imagination. I wear size xl in shirts except for this one. An xl fits like a large. Other than that I like the shirt. I would've given it 5 stars if not for the sizing. I'll give away this one and order an xxl. Just order a size above what you wear and you'll be happy.

Satisfied with color and fit
Size: Small, Color: Light Purple
For the money, this is a good shirt. True, the material is a bit thin and there is a feeling of 'fragility' (loose threads here and there) but the color is nice, the texture is appropriate. The sizing is what I call "New American". I was a medium my whole life but supersizing has made me into a small. I haven't changed, Americans have grown bigger. I am six feet tall and a bit (180+ cm) and weigh 155 pounds (70kg and a bit). The small fits me just fine everywhere but the shoulders are just barely wide enough. If you have slightly wider shoulders but are similar to me otherwise, this may be too tight for you in that one place.

Fits too tight at waist.
Size: XX-Large, Color: Wine
Quality of product satisfactory, however size labeling incorrect. I ordered a XXL that is too tight at the waist. It should be labeled XXL Trim.
