Giới thiệu Bảng mạch phát triển uno atmega 328 p phiên bản 2014 chuyên dụng

Ii.Improvement of funduino:
-working voltage 3.3 v/5v optional.Arduino can only work at 5v, all the time encountered 3.3v level interface module, io port can not be directly connected, need to do level conversion-sd card, bluetooth module, etc.Funduino can work at 3.3v by dialing the switch, when io's level is 3.3v and can work directly with the 3.3v level module.
-stronger power supply.Arduino uses ft232rl's 3.3v output power supply, with a maximum output current of less than 100ma, which is insufficient when it comes to external modules requiring large currents.Funduino uses 1117-3.3 output 3.3v to supply electricity with a maximum current of 500ma.Arduino provides only 5v of 500ma, while funduino provides up to 5v of 2a when using external power.
-more visible led instructions.Arduino's indicator lights are blocked when an extension board is plugged in, and pwr, tx and rx indicators are not visible.Funduino moved the indicator to the edge of the board and could see it even if there was an extension board.
Easier to press reset button.The arduino reset button is blocked when the expansion board is inserted and cannot be reset to the main board.Funduino moves the reset button to the edge of the board and can easily press it whenever possible.
-the extension of the pin.The analog pins of arduino and 3 digital pins are drawn from the universal electronic building blocks/rudder 3pin interface.Many electronic building blocks sensors/control modules, as well as rudder engines, can be connected directly without the need to use sensor extension panels.
-wide input voltage.Arduino supports only 7-12v input, but funduino supports 7-23v input.
-more stable ad sampling.Ad line of arduino is more casual and disruptive, and when iic feet are used for communication (a4a5), other analog pins are affected and cannot be sampled correctly.This problem will not occur on the acd line of funduino.

When dialing the working voltage to 5v, the board is compatible with 100 hundred arduino duemilanove.
