Gumstix Introduces CM4 to CM3 Adapter, Carrier Boards for Raspberry Pi Compute Module 4

Raspberry Pi Trading has just launched 32 different models of Raspberry Pi CM4 and CM4Lite systems-on-module, as well as the “IO board” carrier board. But the company has also worked with third-parties, and Gumstix, an Altium company, has unveiled four different carrier boards for the Raspberry Pi Compute Module 4, as well as a convenient CM4 to CM3 adapter board that enables the use of Raspberry Pi CM4 on all/most carrier boards for the Compute Module 3/3+. Raspberry Pi CM4 Uprev & UprevAI CM3 adapter board Gumstix Raspberry Pi CM4 Uprev follows the Raspberry Pi Compute Module 3 form factor but includes two Hirose connectors for Computer Module 4. The signals are simply routed from the Hirose connectors to the 200-pin SODIMM edge connector used with CM3. Gumstix Raspberry Pi CM4 Uprev is the same except it adds a Google Coral accelerator module. Gumstix Raspberry Pi CM4 Development Board Specifications: […]

New STM32H7 Cortex-M7 MCUs Clock at 550 MHz, Feature Octal SPI Flash and Ethernet Interfaces

STM32H7 Family Matrix with 550MHz Cortex-M7 MCU

STMicro launched STM32H7 single-core Cortex-M7 microcontroller family a while ago, followed by some dual-core Cortex-M7/M4 models, with most clocked up to 480 MHz. The company has now announced five faster parts clocked at up to 550 MHz with STM32H723, STM32H733, STM32H725, STM32H735, and STM32H730 which STMicro claims is “the fastest core speed in the market among MCUs that integrate Flash storage on-chip to run deeply embedded applications”. The embedded flash storage is important, as you may now NXP i.MX RT1170 Cortex-M7/M4 crossover processor can reach up to 1 GHz but does not include flash storage. Key differences in STM32H7 550 Mhz MCUs We’ve highlighted the five new microcontrollers in the table above, and beside the higher 550 MHz frequency delivering 2778 CoreMark and 1177 DMIPS, we can see those are the only parts that support both OctoSPI flash and Ethernet, and all five parts are designed for HMI applications with […]

STMicroelectronics Introduces Zigbee 3.0 to the STM32WB55 microcontrollers

STMicroelectronics has added Zigbee 3.0 support to its STM32WB55 wireless microcontroller family using the Zigbee PRO protocol stack. The STM32 Wireless MCU (STM32WB55) was launched last year with a dual-core Arm Cortex-M4 CPU and Cortex M0+ core, as well as Bluetooth 5 and 802.15.4 radios. STMicro is hoping to expand the applications of the STM32WB into areas like home automation as Zigbee 3.0 is making brands choose Zigbee for their smart-home connectivity solution, smart-lighting, smart-building, mesh IoT connectivity, and many more. The STM32WB55 microcontrollers already provide support for Thread and Bluetooth 5.0 and the inclusion of the Zigbee connectivity will take this to the next level. The STM32WB55 Zigbee 3.0 software includes support for the Exegin Zigbee PRO protocol stack which is available for free. To ease development and deployment, STM32WB Zigbee solution supports 46 Zigbee 3.0 clusters and a further 21 clusters support legacy products and with the Zigbee 3.0 […]

HydraNFC Shield v2 Delivers Up to 1600 mW with STMicro ST25R3916 NFC Chipset

When Benjamin Vernoux is not working on open-source firmware & tools for AirSpy R0/R2/mini SDR, he spends his time on other projects such as HydraBus STM32 board with NFC support which we covered back in 2014. The HydraNFC Shield that came with the board was based on Texas Instruments TRF7970A NFC chipset with limited features and not compliant with any RF/NFC standard. Benjamin has now launched HydraNFC Shield v2 powered by STMicro ST25R3916 NFC chipset and equipped with a differential antenna. The new version of the shield still works with the original HydraBus board and allows much more output power (1,600mW vs 200 mW) and supports a wider range of NFC features & standards. HydraNFC Shield v2 features and specifications: NFC Chipset – STMicro ST25R3916 high-performance NFC universal device supporting NFC initiator, NFC target, NFC reader and NFC card emulation modes Antenna – Differential antenna with power up to 1600mW […]

Edge Impulse Enables Machine Learning on Cortex-M Embedded Devices

Artificial intelligence used to happen almost exclusively in the cloud, but this introduces delays (latency) for the users and higher costs for the provider, so it’s now very common to have on-device AI on mobile phones or other systems powered by application processors. But recently there’s been a push to bring machine learning capabilities to even lower-end embedded systems powered by microcontrollers, as we’ve seen with GAP8 RISC-V IoT processor or Arm Cortex-M55 core and the Ethos-U55 micro NPU for Cortex-M microcontrollers, as well as Tensorflow Lite. Edge Impulse is another solution that aims to ease deployment of machine learning applications on Cortex-M embedded devices (aka Embedded ML or TinyML) by collecting real-world sensor data, training ML models on this data in the cloud, and then deploying the model back to the embedded device. The company collaborated with Arduino and announced support for the Arduino Nano 33 BLE Sense and […]
