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
- ICSP header
- Reset button
- Micro USB connection
- 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs)
- Input voltage (recommended) range from 7V to 12V
- Input Voltage (limit) range from 6V to 20V
- 32KB flash memory of which 4KB used by bootloader
- 2.5KB SRAM
- 1KB EEPROM
Applications
Embedded Design & Development, Industrial, Automation & Process Control, Sensing & Instrumentation, Metering, Consumer Electronics
Warnings
The recommended range is 7 to 12 volts, if using more than 12V the voltage regulator may overheat and damage the board.

Very spacious and beautiful
Size: 23.6 Inch, Color: White, Size: 23.6 Inch, Color: White
A lot of my books fit on here and there’s still more room left if I wanted to buy more books. It’s a simple looking bookshelf but it’s really pretty. It’s also sturdy the only reason I gave it a 4 stars instead of 5 was because it comes with its own plastic screw anchors and they are crap. The shelves were wobbly when we installed them using the plastic screw anchors that came with the packaging. My dad set mine up and luckily he had a bunch of his own so he switched them out with better screw anchors. Once we made that switch it was perfect, there was no wobble or shaking at all. So that’s my only piece of advice. Besides for the screw anchors everything else is perfect

Easy to install

Super easy to install. I use different wall anchors. The anchors like all anchors that come with shelves are not great. The shelves look very clean on the wall.

Easy to install
Size: 23.6 Inch, Color: White, Size: 23.6 Inch, Color: White
This product exceeded my expectations. The installation process was incredibly straightforward—even for someone with little to no experience—and the instructions were clear and easy to follow. Once installed, it feels very sturdy and secure, with no wobbling or shifting at all. You can tell it’s well-designed and made with quality materials. I also appreciated how quickly I was able to set everything up without needing any extra tools or help. Overall, it’s a reliable, user-friendly product that I would absolutely recommend to anyone looking for something dependable and easy to install. Drill is required though.
