The Internet of Things is a network of things ranging from vehicles to household appliances and, the connectivity allows these objects to communicate and share data. It consists of both hardware and software applications.

IoT boards are hardware platforms used to build prototypes of producers ideas.

The top 5 IoT boards for development and prototyping in 2021 are:

Arduino Uno Rev3

The Arduino Uno Rev3 is an open-source Arduino microcontroller board based on the ATmega 328P Microprocessor from the frim Arduino. The board contains input/output (I/O) digital and analogue pins that can connect to other boards expansion (shields) and systems. 

The input/output is 14 digital, analogue inputs 6, a crystal with 16 MHz quartz, a USB connection, an ICSP header and a reset button. To begin, connect it to a USB computer, or power it with an AC-to-DC converter or battery since it comes with all necessary to sustain the microcontroller.

Raspberry Pi 4 Model B

The Raspberry Pi 4 Model-B is the newest low-cost version of the Raspberry Pi computer. There are several upgrades to this electronic board. First, the USB-C power connector may be used, delivering 1.2A for downstream USB devices, with a capacity of an extra 500mA. 

Instead of a type-A (full-size) HDMI connector, a double output displayed on the current board footprint was added, which allows for a pair of type-D (micro) HDMI connections. The Gigabit Ethernet Magjack in Raspberry Pi 4 is at the top on the right instead of underneath the board. It features a new Debian 10 Buster operating system that is available now.

Rock Pi 4C

The Rock Pi 4C is a version of the Rock Pi 4, Rock Chip RK 3399-based SBC by Radxa, which is equally open for US$74.95. It features a Rock Pi 4B model that includes US$74,95, 4GB RAM and a Bluetooth/Wi-Fi module.

A mini-DisplayPort providing dual display compatibility is one of its most vital features. The full-sized RK3399 SoC’s USB Type-C controllers have replaced the HDMI 2.0 connector with the tiny HDMI port and are mini-DP enabled.

Adafruit FONA

The Adafruit FONA MiniGSM is a unique cellular phone module that allows you to add voice, text, SMS, and data to your projects. This board can connect to any global GSM network using a 2G SIM. A microcontroller with a voltage range of 3-5V is also required. 

You can use a headset with an Adafruit FONA to make and receive phone calls, send and receive SMS messages, transmit and receive GPRS data (TCP/IP, HTTP, etc.), and scan and receive FM radio broadcasts from anywhere. 

Giant Board

Giant Board is the world first feather single-board (SBC) computer. It is packed with Debian Linux and a SAMA5D2 ARM Cortex-A5 500MHz microchip. 

It can use LiPo batteries and has MicroSD and up to 128 MB DDR2 RAM storage and memory. It’s a tool aimed to let manufacturers use Adafruit’s Blinka libraries for CircuitPython. It cost approximately $100.
