These pins can be used for both digital input and output operations, making them versatile for various applications. Digital Pins (2-13): The Pro Mini offers a total of 14 digital I/O pins, numbered from 2 to 13.These pins are used to read analog signals from sensors and other analog devices with a resolution of 10 bits. Analog Pins (A0-A7): The Pro Mini has a total of eight analog input pins, labeled A0 to A7.

Like Tx0, it is part of the serial communication interface and can function as a digital I/O pin. Rx1 (Receive): The Rx1 pin is used to receive data from other devices or peripherals into the Pro Mini.It is part of the serial communication interface and can be used as a digital I/O pin when not used for communication. Tx0 (Transmit): The Tx0 pin is used for transmitting data from the Pro Mini to other devices or peripherals.It is essential to ensure that you provide the correct voltage to prevent damage to the microprocessor. Vcc (Voltage Output): The Vcc pin provides regulated voltage to the board, either 3.3V or 5V, depending on the type of board you are using.
You can provide a voltage range of 5V to 12V to this pin, depending on your project's requirements. VIN (Voltage In): The VIN pin is used to power the Pro Mini using an external power supply.When this pin is pulled low (connected to GND), it resets the board, restarting the program execution. RST (Reset): The RST pin is used to reset the microcontroller.These pins are used as the common ground reference for all components connected to the board. GND (Ground): The Pro Mini board contains a total of three ground pins (GND).Let's take a closer look at the pinout of the Arduino Pro Mini: Understanding the pin configuration is essential for interfacing and programming the board effectively. The Arduino Pro Mini board comes with a specific pin configuration that allows you to connect various peripherals and devices to it. This microcontroller, based on Atmega328, offers a wide range of applications, making it a favorite choice for various projects. Just connect the two boards together directly without physically crossing any wires (double check just to be on the safe side as models may differ).The Arduino Pro Mini has gained significant popularity among electronics enthusiasts and hobbyists due to its compact size, flexibility, and cost-effectiveness.

I'm not going to write lots of text about how to connect the two devices together, as the famous saying goes, "A picture is worth a thousand words", hopefully. You can purchase yourself a cheap $1 USB to Serial module like the one pictured below and away you go.
Please Click Here to compare board specifications.ĭon't worry, there is an easy way to get your great programmes developed in B4R into your Pro Mini relatively easily. There is one massive disadvantage it suffers from though, and that is the lack of a onboard serial chip like the CH340G etc, thus no USB connector.ĭepending on what board you are using, you will need to know the following power requirements. Some people class it as a development board which it isn't, it's an installation board, you can tuck it into a small project/hobby box or just place it behind a light switch, plug socket and other small places etc. The Pro Mini does have some advantages over some of the other board on the market, and also some disadvantages too, one advantages is it's small compact size. So you are interested in using an Arduino Pro Mini or compatible board instead of one of the other larger boards to interact with your hardware devices.
