Tiny motor drivers, STM32L4 multi-link IoT nodes, free STM32 IDE, gas detectors, and more – 08 February 2018

The smallest 45 V / 256 microsteps motor driver

The STSPIN820 is the smallest 45 V motor driver in the world that can achieve a resolution of up to 256 microsteps. To achieve a high resolution of 256 microsteps, ST had to develop an advanced and precise PWM current control algorithm. ST’s advanced algorithms are able to keep the torque ripples under control, the motor driver is capable of reducing the noise generated by the motor to come close to a BLDC motor.


Connect directly to the cloud with our STM32 Discovery kit IoT node

The STM32L4 Discovery kit IoT node (B-L475E-IOT01A) with multi-protocol RF connectivity helps you create smart low-power IoT nodes with optimized range and battery autonomy. A full set of sensors for user interaction and environmental awareness, and the possibility to easily add others, make this board an ideal sensor-to-cloud prototyping platform.


Feature-rich TrueSTUDIO for STM32 IDE available for free

Acquired by ST in December 2017, Atollic TrueStudio IDE can now be downloaded by all STM32 users free of charge. Designed for use with the STM32 development ecosystem, this full-featured version includes a build/memory analyzer, stack analyzer, trace & profiling, RTOS-aware debug, and single and multi-core debug with support for ST-Link and J-Link debug probes. No license needed!


New multi-brand dual-interface payment solution

STPay-Tiger is a new STPay JVM platform based on the ST31G480 secure MCU with 135 Kbytes of user Flash memory for personalization data or custom applications. Validated with various antenna technologies, it currently embeds four payment applications: Visa VSDC 2.9, MasterCard M/Chip Advance 1.2.1, JCB D.1.1 and Interac Flash 1.5. Whatever your needs, this flexible platform can be tailored to fit your project.

Get started with STM32 Nucleo pack for electrochemical toxic gas sensing

Tasteless and odorless, carbon monoxide is a highly toxic inhalant that can be lethal, which is why we need detectors to prevent intoxication risks. The P-NUCLEO-IKA02A1 pack is a ready-to-use CO detector including an STM32 Nucleo expansion board based on two TSU111 op amps and a Figaro TGS5141 CO sensor.


A wireless home carbon monoxide detector can save lives

Carbon monoxide detectors measure CO levels and set off an alarm before it becomes dangerous. Our S2-LP, sub-1GHz RF transceiver and TSU111 op amps can be used with STM32 MCUs to create advanced wireless detectors for remote monitoring services on phones or wearables and is especially useful for people hard of hearing, partially sighted or sleeping.
