SPDUINO (ARDUINO-COMPATIBLE BOARD)

The SPDuino is a clone of Arduino Mainboard with ATMEGA328 (Dumilanavo Bootloader). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.

This board can be powered via the USB connection or with an external power supply. The power source is selected automatically using auto reselect circuit.

FEATURES

• 100% Arduino (Dumilanavo)-compatible board

• Direct USB interface, no extra converters are required
