flashtree 3pcs Nano I/O Expansion Multi-Purpose Extension Sensor Shield Module for Arduino UNO R1 R3 Nano

  Features: The extension board is specially tailored for arduino NANO, welding on the two rows of pins, can be used in Arduino duemilanove 2009, UNO R1. It expands the Nano Controller’s ability to connect to these devices in a simple and trouble-free manner. 14 input/output pins (servo type with GND, power and signal), 8 analog pins with power output and GND. External power supply is as follows: DC adapter power supply 9V, the pin voltage is 5V-5.25V (can meet the pin voltage, drive the high power load). USB is as follows: USB supplies NANO to 5V and pin voltage is 5V-5.25V (can drive sensors and other modules).
