This Crowduino Pro Mini is fully compatible with the original Arduino Pro Mini. We've added two analog IO pins (A6, A7) and an auto - recovery fuse on the power input side. It allows simultaneous use of USB and power supply. It's a microcontroller board based on the ATmega328. It has 14 digital input/output pins (6 can be PWM outputs), 8 analog inputs, an on - board resonator, a reset button, and holes for pin headers. A six - pin header can connect to an FTDI cable or USBSerial Adapter for USB power and communication. This 5V Arduino runs the 16MHz bootloader (select 'Arduino Duemilanove w/ 328' in Arduino software). The Pro Mini doesn't come with pre - populated connectors, giving you flexibility. Ideal for newbies with our recommendation of starting with Crowduino or Arduino Duemilanove. The Pro series suits users aware of system voltage (5V) limits, lack of connectors, and off - board USB. Features include an ATmega328 running at 16MHz with external resonator (0.5% tolerance), 5V regulator, DC input from 5V to 12V, 14 digital IO, 8 analog IO, and reverse polarity protection. It measures 33.3 * 18.0mm.
Using the Crowduino Pro Mini is easy. First, connect it to an FTDI cable or USBSerial Adapter through the six - pin header for power and communication. Select 'Arduino Duemilanove w/ 328' in the Arduino software. You can start coding and experimenting right away. Remember, it runs on a 5V system, so make sure your power supply is within the 5V - 12V range. The board doesn't come with pre - soldered connectors, so you can solder the connectors or wires according to your needs. Be careful with the reverse polarity protection, don't connect the power in the wrong way. For maintenance, keep it in a dry and clean place. If you're a first - time user, we suggest starting with the Crowduino or Arduino Duemilanove to get familiar with the basics.
