DFRduino Pro Mini V1.3(8M3.3V328)

The DFRduino Pro Mini V1.3 is a 3.3V, 8MHz microcontroller board based on the ATmega328, fully compatible with the Arduino Pro Mini. It's an advanced alternative to the official Arduino Pro Mini, boasting 8 analog inputs compared to the official's 6. This board runs an 8MHz bootloader, and you can select 'Arduino Duemilanove w/ 328' in the Arduino software. It features 14 digital input/output pins (6 usable as PWM outputs), 8 analog inputs, an on - board resonator, a reset button, and holes for mounting pin headers. A six - pin header allows connection to an FTDI cable or DFRobot breakout board for USB power and communication. Designed for semi - permanent installation in objects or exhibitions, the board comes without pre - mounted headers, enabling you to use various connectors or directly solder wires. Its pin layout is compatible with the Arduino Mini. For programming and powering your Mini pro board, we recommend either the FTDI Basic Breakout 3.3/5V (Arduino Compatible) or the USB Serial Light Adapter (Arduino Compatible). Note that compared to the standard DFduino Pro Mini 8Mhz, this V1.3 version has reversed pins on the programming interface. **Specifications**: - DC input: 3.3V up to 8V (from RAW pin); 3.3V (from VCC pin) - Bootloader: Arduino Pro/Pro Mini (3.3V, 8MHz) w/ Atmega328 - 3.3V regulator with a max 150mA output - ATmega328 running at 8MHz with external resonator (0.5% tolerance) - No need for interfacing circuitry with 3.3V devices like GPS, accelerometers, and sensors - Off - board USB connection - Supports auto - reset - Over - current and reverse - polarity protection - On - board Power and Status LEDs - Size: 0.7x1.3' (18x33mm) - Environment - friendly: Rohs Compliance **Documents**: - Schematic - LDO regulator datasheet - Getting Started Tutorial - Arduino Pro Mini homepage **Shipping List**: - DFRduino Pro Mini V1.3(8M3.3V328) x1

Using the DFRduino Pro Mini V1.3 is quite straightforward. First, if you want to program and power the board, you can choose either the FTDI Basic Breakout 3.3/5V or the USB Serial Light Adapter. Connect the six - pin header on the board to the appropriate cable or breakout board for USB power and communication. When it comes to programming, open the Arduino software and select 'Arduino Duemilanove w/ 328'. The board's advanced design with 8 analog inputs gives you more flexibility for projects involving sensors. Some important notes: This V1.3 version has reversed pins on the programming interface compared to the standard DFduino Pro Mini 8Mhz, so be careful during connections. Also, make sure the power supply is within the specified range of 3.3V to 8V from the RAW pin or 3.3V from the VCC pin. For maintenance, keep the board in a dry and clean environment. Since it has over - current and reverse - polarity protection, you don't have to worry too much about small mistakes in power connections. But still, avoid exposing it to extreme temperatures or physical damage. The on - board Power and Status LEDs can help you quickly check the board's working condition.
