Features:<br> The smaller sized V3 based-on ATmega168 micro-controller (16MHz) can be used with the model board for solderless wiring (experimental board).<br> It has similar structure with Arduino Diecimila/Duemilanove, but different size, to reduce the size, the components are installed on both sides of the printed circuit board.<br> Adopts CH340G chip as UART-USB converter, stable data exchange results can be obtained at 12Mhz operating frequency.<br> The Nano Version3 can be powered through the mini USB port (up to 500mA). The external power supply 6-12v outputs VINor 5V, and the output of the external power supply adjusted to 5V. The power supply automatically selects the max-voltage.<br> This nano ATmega168 has a V3 pin out instead of V2.<br> <br> Specifications:<br> Material: ABS+Printed Circuit Board<br> Length: Approx. 4.5cm/1.77inch<br> Type: Welding, Non Welding(optional)<br> Technical Parameters of Arduino Nano:<br> 12 digital input/output ports D2-D13.<br> 8 analog input ports A0-A7.<br> 1 pair of TTL-level serial port transceiver ports RXandTX.<br> 6-PWM ports, D3-D5-D6-D9-D10-D11.<br> Using Atmega168P-AU microcontroller.<br> Support USB download and power supply.<br> Support external 3.3V-12V DC-power supply.<br> Support lithium battery and 9V battery power supply.<br> Support ISP download.<br> <br> Note:<br> Please allow 0-1cm error due to manual measurement, make sure you do not mind before you order.<br> Please allow slight chromatic aberration due to different display resolutions.<br> <br> Package includes:<br> 1x Development Board
