Minimization of IoT applications production costs – STM32WB and proven related components

Generally understood IoT is one of the fastest growing branches of electronics. New microcontrollers and components introduced to the market give unprecedented possibilities. One of the most interesting proposals recently introduced to the market is the STM32WB series from STMicroelectronics.

The STM32WB platform is an evolution of the well-known market leading STM32L4 of ultra low power series. It provides the same digital and analog peripherals suitable for applications requiring longer battery life and complex functions. The integration of calculation and transmission lines makes this family a part of current global trends.


Bluetooth and energy efficiency

The STM32WB family is equipped with a certified radio module in accordance with the IEEE802.15.4 standard. This module has been attached to the Cortex-M0 + core which significantly reduces the load of the main processor. The microcontroller provides support for Bluetooth 5.0 (BLE) as well as Open Thread and ZigBee.

The FlexPowerControl used in STM32WB increases the flexibility of power mode management and significantly reduces overall energy consumption. Run Mode enables the M4 core clocking with a frequency of up to 64 MHz and with a current consumption of 117 µA / MHz.

For Field Application Engineers (FAE), the release of development modules with a representative of the STM32WB family by the STMicroelectronics is certainly good news.

MLPF-WB55-01E3 RF Filter – dedicated products

For the STM32WB microcontroller we recommend a dedicated MLPF-WB55-01E3 filter that integrates a matching impedance network with a harmonic filter. The matching impedance network is adapted to maximize the RF performance of STM32WB55xx. The device uses IPD STMicroelectronics technology which optimizes the operation of radio waves.

What about antennas?
Choosing the right antenna for mobile and the Internet of Things (IoT) applications is not easy. It is worth using the knowledge and experience of specialists. We recommend antennas specially designed for embedded applications made by Swedish company – Proant. OnBoard SMD 2400 antennas are a series of small antennas that operate on the 2.4 GHz ISM band and are suitable for applications with Bluetooth, WLAN, Wi-Fi, Zigbee, etc.

Unictron antennas are another proven proposition, especially AA055U. AA055U is an excellent choice for Wi-Fi / Bluetooth solutions. The antenna covers bands from 2400 to 2500 MHz and can provide 250 MHz bandwidth on a demo board.

Comprehensive solutions at your fingertips

When designing applications, microcontrollers are just one of many components of the entire project. With many years of experience in the selection and use of components, Masters engineers recommend aslo related products from proven companies – inductances from Chilisin, dedicated antennas from Unictron i Proant and quartz from NDK.
