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

The 3.3V DFduino Pro Mini 8Mhz(Arduino Pro Mini Compatible) is a microcontrollerboard based on the ATmega328.It is a 3.3V DFduino running the 8MHz bootloader(select 'Arduino Duemilanove w/ 328' within the Arduino software).It is an advanced version of official Arduino Pro Mini. The DFRduino Pro minihas 8 analog inputs compared with official 6. The rest bits are exactly thesame.It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 8analog inputs, an on-board resonator, a reset button, and holes for mounting pinheaders. A six pin header can be connected to an FTDI cable or DFRobot breakoutboard to provide USB power and communication to the board.The DFRduino Pro Mini is intended for semi-permanent installation in objects orexhibitions. The board comes without pre-mounted headers, allowing the use ofvarious types of connectors or direct soldering of wires. The pin layout iscompatible with the Arduino Mini.Low-voltage board:Needs no interfacing circuitry to popular 3.3V devices and - modules (GPS,accelerometers, sensors, etc)Specifications:- DC input 3.3V up to 8V(power supply from RAW pin)- DC input 3.3v(from VCC pin)- Bootloader: Arduino Pro/Pro Mini (3.3V, 8Mhz) w/ Atmega328- 3.3V regulator- Max 150mA output- ATmega328 running at 8MHz with external resonator (0.5% tolerance)- USB connection off board- Supports auto-reset- Over current protected- Reverse polarity protected- On board Power and Status LEDs- Size:0.7x1.3" (18x33mm)- Envionment Friendly: Rohs Compliance
