$10 LoRa-E5 STM32WL module offers LoRaWAN networking in a 12x12mm package

Over the years, we’ve seen many LoRa modules combining STM32 microcontroller with Semtech SX12xx wireless transceivers, so that’s probably why STMicro decided to create the first LoRa SoC with STM32WL that was launched last year. I’ve just been informed a tiny (12x12mm) LoRa-E5 module based on STM32WL LoRa SoC working with 868 MHz and 915 MHz bands had recently launched on Seeed Studio for $9.90.

New STMicro STM32G4 MCUs target cost-effective motor control systems with up to 512KB flash

STMicro introduced the STM32G4 family of mixed-signal microcontrollers in May 2019 for e-mobility (e.g. e-bikes), digital power supplies, advanced motor controls, lighting, and building-automation products. The Arm Cortex-M4 based microcontrollers clock up to 170 MHz, and include new hardware mathematical accelerators to boost processing of applications using Cordic (Coordinate Rotation Digital Computer) and Filtering functions to support increased performance and energy efficiency. This enables faster and more efficient calculations for energy-saving motor controls and frees up the core to receive more sensor data and control additional user functions. The STM32G4 Series of mixed-signal microcontrollers have three lines of products: The STM32G4x1 Access line – general-purpose microcontrollers with an entry-level set of analog peripherals The STM32G4x3 Performance line – general-purpose microcontrollers with the maximum number of analog peripherals The STM32G4x4 Hi-resolution line with high-resolution timer and complex waveform builder plus event handler (HRTIM) for digital power conversion, such as digital switched-mode power supplies, lighting, welding, solar and wireless charging At launch, […]

Arduino Portenta H7 Gets Embedded Vision Shield with Ethernet or LoRa Connectivity

[Update January 28, 2021: The LoRa version of Portenta Vision Shield is now available] Announced last January at CES 2020, Arduino Portenta H7 is the first board part industrial-grade “Arduino Pro” Portenta family. The Arduino MKR-sized MCU board has plenty of processing power thanks to STMicro STM32H7 dual-core Arm Cortex-M7/M4 microcontroller. It was launched with a baseboard providing access to all I/Os and ports like Ethernet, USB,  CAN bus, mPCIe socket (USB), etc… But as AI moves to the very edge, it makes perfect sense for Arduino to launch Portenta Vision Shield with a low-power camera, two microphones, and a choice of wired (Ethernet) or wireless (LoRA) connectivity for machine learning applications. Portenta Vision Shield key features and specifications: Storage – MicroSD card socket Camera – Himax HM-01B0 camera module with 324 x 324 active pixel resolution with support for QVGA Image sensor – High sensitivity 3.6μ BrightSense pixel technology Microphone – 2x MP34DT05 omnidirectional microphones Connectivity Ethernet version- 10/100M […]

DevEBox STM32H7 Development Boards are made for Factory Automation

When it comes to STMicroelectronics’ STM32H7 series, there are three product lines- Dual-core lines, Single-core lines, and Value lines. ARM Cortex-M7 based – STM32H7 MCU series is capable of delivering 1327 DMIPS/ 3224 CoreMark. These MCUs are designed for factory automation (HMI, process control, power management), connectivity & security (Alarm panel, Wireless Modules). To continue with the growth of the STM32H7 series, we have China-based MCUdev DevEBox’s STM32H7XX-M development boards taking a single-core line and a value line module. The two STM32H7XX-M development boards use STM32H743VIT6 and STM32H750VBT6 core modules. The STM32H743VIT6 comes from a single core line that offers ARM Cortex-M7 gets up to 2 Mbytes of dual-bank flash memory and 1 Mbytes of RAM. While the STM32H750VBT6 module from the value line is one of the cost-effective STM32H7 devices featuring 128 Kbytes of flash memory. STM32H7 Development Boards These boards from MCUdev measure approximately 40mm x 68mm in size with the same peripherals. The manufacturer has produced both […]
