Funduino Nano Expansion Board + ATmega328P Nano V3 No Welding For Arduino

Funduino Nano Expansion Board + ATmega328P Nano V3 No Welding For Arduino Description: Funduino Nano Expansion Board This Nano Mult-Function expansion board is designed specially for Arduino Nano, solve the problem of wiring confusing when a variety of sensors connected. Lead out all digital IO port and analog IO port, each one with standard positive and negative power interface. Lead out the I2C interface of mainboard for convenient connection. Increasing the DC power supply interface. Nano USB interface supply current is actually only 50MA, to bring high-current devices, such as the steering, is obviously insufficient. So in the DC power connector provide external power supply to ensure the stability of equipment operation. ATmega328P Nano V3 Improved Version Microcontroller Atmel ATmega328 Operating Voltage (logic level): 5V Input Voltage (recommended): 7V ~ 12V Input Voltage (limits): 6V ~ 20 V Digital I/O Pins: 14 (of which 6 provide PWM output) Analog Input Pins: 8 DC Current per I/O Pin: 40mA Flash Memory: 32KB (ATmega328) (of which 2 KB used by bootloader) SRAM: 2KB (ATmega328) EEPROM: 1KB (ATmega328) Clock Speed: 16MHz Note: Have changed the USB chip, can improve the download speed and stability of WIN7/WIN8 This version is no welding and not included the USB cable. Package included: 1 x Funduino Nano Expansion Board 1 x No welding Arduino Compatible Nano V3.0 Board
