This is the final version of my Arduino Nano Experimenter’s Board. It’s a breakout board that allows you to experiment with an Arduino Nano and many different sensors and modules without having to worry about the wiring.
There are breakouts for I2C(3),SPI,RGB LED,DHT11. There are 3 LEDs all PWM cabale and one with an interchangable resistor. 3 pushbuttons with pullup resistors going to 3 different digital pins, a 10 pot on an analog pin and a light dependent resistor. It will run from the Nano’s Vreg, but I have included an external 7805 regulator witch shares a common ground with the Arduino. this way you can bypass the Arduin’s 200mA (MAX) total current by only running the switching through the Arduino and the power through the external regulator.
