The Internet of Things (IoT) is continually growing larger, while the devices used in it are shrinking in size, yet becoming more powerful. The advent of Bluetooth and microprocessors has aided in this evolution, shrinking component footprints and increasing connectivity speeds. STMicroelectronics’s BlueNRG-232 has combined both of these influential technologies into a self-contained SoC, capable of functioning autonomously.
The BlueNRG-232 has 256 KB of programmable Flash memory and 24 KB of RAM, and its integrated linear regulator and step-down converter trim down its power needs, making it an efficient choice for a single unit Bluetooth communicator. The board additionally has a set of onboard oscillators to provide redundancy in timing. If those features weren’t enough, a 5.0 mm2 footprint gives the BlueNRG-232 amazing compactness.
The BlueNRG-232 addresses industry demands, incorporating Bluetooth connectivity into a small, reliable package, with applications all over the IoT, from wearable devices and computing peripherals to medical and security uses.
