I shall list these pins, and what they’re connected to, now: GPIO Pin Number This means that there are SPI pins on the GPIO that you can no longer use for other purposes. It must be noted that the nRF24L01+ chip is connected to the ATmega328P chip directly on the board. This means you can do a direct MCU swap on existing projects or prototypes using the Arduino Nano R3 dev board, for Nano-RF dev boards. There is certainly no shortage of choice in this area, either!įrom the most simple modules, such as the 433MHz HC-12 UART radio, to the slightly more complex nRF24L01 SPI, or Bluetooth (JDY-33, DW-CT14, AT-09 etc), or WiFi, or LoRa, or even GPRS/LTE… the options are practically limitless.Īs you can see, the Microcontroller specifications are identical to the Arduino Nano R3 development board. Readers with more experience working with Arduino and other MCUs will very likely have experienced adding radio modules to their devices. We have, at times, gone so far as to build line-of-sight optical laser communications into our devices, sometimes even with optical repeater devices necessary to span distances of multiple kilometres, where low-latency is a concern. No, seriously! More than half of all of the projects we develop require multiple devices to communicate without wires, sometimes over vast distances. We here at Flowduino build a lot of wirelessly interconnected devices. So, please enjoy this Review-Tutorial (“ Reviewtorial?”) The Problem… Where most publications produce Reviews as strictly-informational articles covering a particular product or service Flowduino is all about education!įor this reason, we present every Review with at least one Tutorial element.Īfter all, how better to review a Microcontroller, Sensor, IO device, or Development Board than to walk through a project using them? Before we begin, we want to briefly explain the format of this Review article.
