IoT Boards and Modules

Written by Sam Wallace

Connect to the Internet of (All of the) Things

The Internet of Things (IoT) is everywhere and growing, and thus the need for highly integrated modules designed for the edge IoT is greater than ever. This month’s Datasheet rounds up just a corner of the latest offerings in IoT modules and boards that are on the market and ready for implementation.

  • IoT edge modules
  • ADLINK’s Express-RLP COM Express Type 6
  • Avnet’s RASynBoard Core Board
  • Digi’s ConnectCore MP1
  • Infineon’s AIROC CYW43022
  • Laird Connectivity’s Sterling-LWB+ Wi-Fi 4
  • NXP’s K32W148
  • Renesas RYZ024A
  • Reyax’s RYS8839
  • STMicroelectronics ST87M01

The Internet of Things (IoT), at this point, needs no introduction—least of all to readers of Circuit Cellar. Its ubiquity speaks to its central importance to modern embedded design, and its continued rapid growth over the coming decade(s) is perhaps third on the list of life’s certainties behind death and taxes. To that extent, virtually everything discussed in the pages of this magazine nowadays touches, in some way, on the IoT in its many incarnations.

IoT edge devices are comprised of a combination of embedded processors and microcontrollers (MCUs) that provide intelligence, along with various wireless, cellular, and other connectivity solutions to connect to the network. IoT system designers often produce modular solutions that deliver both intelligence and connectivity—and that must, of course, meet a variety of vital certifications to make implementation seamless. The following gallery highlights some of the most exciting modules to come out over the last 12 months.

In addition to those products, we have included a board offering from Avnet, complete with processor, MCU, and Wi-Fi/BT modules. Read on for the details. Their product is also available as part of a larger evaluation kit, which includes an I/O board for prototyping and development. Meanwhile, certain popular companies are conspicuously absent: Espressif, for example, whose ESP32 MCU is to be found everywhere in our authors’ projects, lately. This exclusion was merely a byproduct of trying to find the latest modules available, and should not be misread as any kind of snub.
