Input and OutputEach of the 14 digital pins on the Nano can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions. Some pins have specialized functions:Serial: 0 (RX) and 1 (TX). Used to receive (RX) and transmit (TX) TTL serial data. These pins are connected to the corresponding pins of the CH340G USB chip. The Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Nano 3.x). It has more or less the same functionality of the official UNO, but in a different package. It lacks only a DC power jack, and works with a Mini-B USB cable instead of a standard one. You could download the driver of Nano V3.0 . ATTENTION: We dont have USB cables in this kit and you will need to buy a mini USB cable to use this NANO board. Package Include : 3 X Nano Board PCB Size: 18 x 45 mm Weight: 7 g. | ![]() B00FAQSMR2 Price: $14.99 Score: 7.813 Category: Electronics Rating: 5 Votes: 4 Find similar productsFTDI USB to Serial Breakout Board - Three Pack of The VisiPort2. Designed, Assembled, Tested and Distributed in the USAThis item includes three VisiPortsThe VisiPort2 is a USB To Serial Module that has been designed to program Arduinos. Its small size allows it to fit into bread board where other programmers are too big and bulky. It is designed to program Arduinos. Its six pin female header connects easily to a Mini Pro with no bread board needed. It has one green LED that indicates power is applied to the FTDI chip. There are two amber LEDs to indicate when Tx and Rx are active. The VisiPort2 works with 5Volt and 3.3Volt Arduinos Use the three pin jumper in the upper right corner to select I/O voltage of the VisiPort2. This selection allows compatibility with all Arduinos. The VisiPort2 Uses a Micro USB Connector The Micro USB connector is lower profile and allows cables to connect into the center of the VisiPort2. This keeps the overall size smaller than any other programmer. The VisiPort2 has a Flexible Arduino Reset We gave the VisiPort2 jumper selectable DTR or RTS reset capability. |

The SparkFun Qwiic HAT for Raspberry Pi (not included) is the quickest and easiest way to enter into SparkFun’s Qwiic ecosystem while still using that Raspberry Pi that you’ve come to know and love. The Qwiic HAT connects the I2C bus (GND, 3.3V, SDA and SCL) on your Raspberry Pi to an array of Qwiic connectors on the HAT. Since the Qwiic system allows for daisy chaining boards with different addresses, you can stack as many sensors as you’d like to create a tower of sensing power! The Qwiic Pi HAT has four Qwiic connect ports, all on the same I2C bus. In addition, many of the useful GPIO pins on the Raspberry Pi are broken out. This HAT is compatible with any Raspberry Pi that utilizes the standard 2x20 GPIO header. It has been designed to sit to the side of the Pi, allowing it to work conveniently with a Pi Tin enclosure to connect boards to the Qwiic ports. The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong. Note: There is a small silk error that has reversed the SDA and SCL. This is simply a cosmetic mix-up and will not impact any function with this board. | ![]() B079164TQZ Price: $7.99 Score: 7.634 Category: Electronics Rating: 4.4 Votes: 24 Find similar productsNextion Enhanced IO Adapter GPIO Expansion Board for Nextion Enhanced 2.4 2.8 3.2 3.5 4.3 5 7 Intelligent Display 7 10.1 inch.
