This is the first development board of Arduino to utilize a microcontroller with an in-built USB. This board handles USB directly. Therefore, there are code libraries that enable the board to copy a computer mouse, keyboard, and more.
The redboard is very reliable and simple. You can use the Arduino IDE to program the RedBoard over a USB Mini-B cable. This board will function well on Windows 8 without changing the security settings. Since it features a USB/FTDI chip, it is more stable. Also, it has a flat back, which makes embedding much easier on projects.
Arduino Uno (R3)
This is an ideal choice for beginners. The Arduino Uno PCB is simple and it features everything you need to begin your project. This board has got 14 digital output/ input pins. Arduino Uno features everything that helps to support the microcontroller.
Arduino Mega (R3)
This is similar to the Arduino Uno PCB. The Arduino Mega features several digital output/input pins. You can simply use a USB cable to connect it to a computer. Also, you can power it with a battery to begin your project. Arduino Mega is very useful for projects that need some digital outputs or inputs.
Types of Pins on the Arduino PCB Board
The Arduino circuit board features several pins. These pins serve different functions.
These pins function as normal digital pins. However, you can use them for something like Pulse-Width Modulation (PWM). Also, these pins can simulate analog output.
Digital pins can serve as digital output and digital input. It can power an LED and also indicate if a button is pushed.
This means Analog Reference. AREF can help to set external reference voltage. This voltage ranges between 0 and 5 volts as the higher limit for the analog input pins.
Analog pins can detect and interpret the signal from an analog sensor. For instance, it can read temperature sensors and transform it into a value you can read.
3.3v and 5v
The 3.3v pin provides 3.3 volts of power while the 5V pin offers 5 volts of power. The majority of the simple components in Arduino can function without 3.3 or 5 volts.
Arduino Shield PCB
The Arduino shield PCB is a pre-built board placed on top of Arduino boards. This shield offers additional functions like:
- It controls motors
- Offers cellular or wireless communication
- Controls an LCD screen
