OSD32MP1-RED full-featured STM32MP1 development board launched for $265

OSD32MP1-RED development board was first announced last year together with another board based on Octavo Systems OSD32MP1 System-in-Package (SiP). The chip packs an STMicro STM32MP1 Cortex-A7/M4 processor, up to 1GB DDR3L memory, 4KB EEPROM, a PMIC, two low-power MEMS oscillators, over 100 passive components into a single 18x18mm 302 Ball BGA package. The company has now just announced the availability of the OSD32MP1-RED development platform on DigiKey, Arrow, and Mouser for around $265 and up. There have been a few modifications to the design with, for instance, the USB header replaced by a USB Type-A connector, but the most notable difference is that OSD32MP1-RED is now using a green PCB instead of the red one showed during the first announcement… OSD32MP1-RED specifications: SiP – Octavo Systems OSD32MP157C-512M-BAA with STM32MP157C SoC with dual-core Arm Cortex-A7, Cortex-M4 real-time core, plus 512MB DDR3 memory, STPMIC1A power management chip, EEPROM, oscillator, and passive components […]

Use Scheme functional programming language with LambdaChip Alonzo STM32 board

LambdaChip Alonzo STM32 Scheme functional programming

Most MCU-based embedded systems come with firmware programmed with assembler, C, and/or C++. But as referenced in a paper published in 2000 entitled ” Point of view: Lisp as an alternative to Java“, functional programming languages like Lisp or Scheme may lead to shorter development times compared to C/C++ or Java. That’s with this idea in mind that LambdaChip was created. It is a lightweight, open-source virtual machine designed to run on embedded systems with limited resources, for instance, an 80MHz microcontroller with 50KB RAM, and programmable with Scheme multi-paradigm programming language, a dialect of Lisp widely used for functional programming research and teaching. The company behind the project, also called LambdaChip, has just created its own hardware with LambdaChip Alonzo, an STM32 Cortex-M4 development board with 512KB flash, 128KB RAM, and that also comes with Bluetooth LE connectivity. LambdaChip Alonzo board specifications: MCU – STMicro STM32F411CEU6 Arm Cortex-M4 MCU […]

STM32U5 Cortex-M33 MCU gets more performance, 2D graphics accelerator, and advanced security

STM32U5 development board B-U585I-IOT02A Discovery kit

The first STM32 MCU based on Arm Cortex-M33 core was the ultra-low-power STM32L5 microcontroller, and the company is now following up with the STM32U5 series also designed for smart applications including wearables, personal medical devices, home automation, and industrial sensors. The new family has a higher 160 MHz clock speed, up to 2048 KB flash, up to 786 KB RAM, a 2D graphics accelerator, several peripherals have been upgraded, and a new autonomous mode lets DMA and peripherals keep working while most of the device sleeps in order to save power. STM32U5 MCUs also integrate additional hardware security features, and are manufactured using a 40nm process, which the company says is the most advanced process suitable for microcontrollers. Just like for the STM32L5 family, there are two product lines in the STM32U5 series which mostly differ in their security features: STM32U575 with 1024 to 2048 KB of flash memory, 786 […]

$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.

Linux 5.11 Release – Main Changes, Arm, MIPS & RISC-V Architectures

Linus Torvalds has released Linux 5.11 just in time for… “Valentine’s Day”: Nothing unexpected or particularly scary happened this week, so here we are – with 5.11 tagged and pushed out. In fact, it’s a smaller-than-average set of commits from rc7 to final, which makes me happy. And I already have several pull requests lined up for tomorrow, so we’re all set for the merge window to start. But in the meantime – and yes, I know it’s Valentine’s Day here in the US – maybe give this release a good testing before you go back and play with development kernels. All right? Because I’m sure your SO will understand. Linus Last time around, Linux 5.10 was an LTS release that added EXT-4 performance enhancements, improved post-Spectre performance, as well as the enablement of BCM2711 (Raspberry Pi 4) display pipeline, among other many changes. Some of the notable changes in […]

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 […]
