Nano V3 Board ATmega328P CH340 Controller with 0.91'' OLED Display for Arduino
Nano V3.0 with Built-In OLED Completely compatible with Arduino Nano and Arduino IDE. Small, complete, and user-friendly, it offers the same connectivity and specs of the Nano board. It is larger than the original Nano board to accommodate the screen. (see comparison picture) This board works the same way as original Nano, runs perfectly on programming software, and fully compatible with Windows, Mac and Linux operating system. It integrates a 0.91 inch OLED display, without the need for any wires or breadboards. The OLED display has a 128X32 high-resolution, with no backlight and works with SSD1306 driver. The Board uses I2C for connecting to OLED Display (I2C: A4 (SDA) and A5 (SCL)) It is equipped with original ATmega328P chip and CH340 chipset for USB communication. It uses a Mini-B USB port, just like the original Nano. 7-12V unregulated external power supply (pin 30), or 5V regulated external power supply (pin 27). The power source is automatically selected to the highest voltage source. The pins come soldered to the bottom of the board.
