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 […]

Arduino MKR IoT Carrier embeds display, sensors, and I/Os for IoT projects

Arduino Oplà IoT Kit was launched last fall as the first open programmable IoT platform from the company. The kit included everything you need to create your own IoT devices with MKR IoT carrier with a 1.3-inch OLED color display, environmental sensors, capacitive touch buttons, Arduino MKR WiFi 1010 board, external PIR motion and moisture sensors, a circular plastic enclosure, and various cables. But the community soon wanted to only buy the carrier board without having to purchase the whole kit, so Arduino has just started to sell MKR IoT Carrier board as a standalone product. Arduino MKR IoT Carrier features & specifications: Compatible with Arduino MKR family boards with WiFi, LoRa, NB-IoT, or 3G cellular connectivity Storage – MicroSD card holder Display – Round 1.3-inch OLED display I/Os 2x 24V relays 3x Grove connectors include two analog and one digital (I2C) Sensors – Temperature, humidity, pressure, RGBC light, gesture […]

LiPo battery powered Olimex boards use ESP32-S2’s USB OTG interface

Last year, Olimex introduced ESP32-S2-DevKit-LiPo and ESP32-S2-WROVER-Devkit-LiPo boards optimized for battery-powered applications with as little as 30uA deep sleep power consumption. ESP32-S2 processor comes with a USB OTG interface, but at the time, Espressif Systems ESF-IDF SDK did not support programming via the built-in USB interface, so Olimex added CH340T USB to serial converter for programming. The good news is that the SDK can now support USB programming without an external chip, so the company designed new versions of the boards without a USB to serial chip with namely ESP32-S2-DevKit-LiPo-USB and ESP32-S2-WROVER-Devkit-LiPo-USB boards. The specifications are basically the same as previously except for the removal of the USB to serial chip, support for USB OTG, and even lower power consumption: Wireless module: ESP32-S2-DevKit-LiPo – ESP32-S2-WROOM with Espressif ESP32-S2 single-core 32-bit LX7 microprocessor up to 240 MHz with 128 KB ROM, 320 KB SRAM, 16 KB SRAM in RTC, 4MB SPI […]

$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. LoRa-E5 key features and specifications: SoC – STMicro STM32WLE5JC Arm Cortex-M4 MCU @ 48 MHz with 256 KB flash memory, 64 KB SRAM, SX126x LoRa radio LoRa connectivity Tx power – 22dBm @ 868/915MHz -136.5dBm sensitivity for SF12 with 125KHz BW 158dB link budget Embedded LoRaWAN protocol, AT command Frequency ranges – EU868, US915, AU915, AS923, KR920, IN865 I/Os – 3x UART, 1x I2C, 1x 12-bit ADC, 1x SPIO Supply Voltage – 3.3V Power Consumption As low as 2.1uA sleep current in WOR mode Tx […]

Feather compatible shield Integrates BG96 Module with LTE Cat-M1, NB-IoT, and GPS

Last week, I wrote about the Pebble Board, an nRF9160 based LTE-M and NB-IoT GPS tracker board that connects with Thingsboard. I was soon informed about a similar solution based on Quectel BG96 and compatible with the Feather form factor. Meet IoT-Bots.com’s qTop Adafruit Feather Compatible shield. In case you wonder, why they did not call it a FeatherWing, that’s because as it’s slightly larger, and the boards are “Adafruit Feather Compatible (AFC) from the interface connection perspective only.” Key features and specifications: Wireless module – Quectel BG96 Cellular – LTE Cat M1, NB-IoT, and EGPRS module offering maximum data rates of 375 kbps downlink and uplink GNSS – GPS, GLONASS, BeiDou/Compass, Galileo, QZSS Nano SIM card holder and u.FL connector (3) for cellular connectivity u.FL connector (4) for GNSS Expansion Feather expansion connector (11) 6-pin qJam interface connector (12) with I2C for extra sensors Misc – Network status LED, […]

CN0549 CBM development kit monitors assets through vibration analysis

CN0549 CBM Development Kit interfaced with SMA Connector

Condition Based Monitoring (CBM) has become quite popular in the manufacturing sector due to its advantages. It is a type of pre-analysis monitoring that includes the use of sensors to evaluate the status of an asset over time while it is in operation. Hence, the data collected is used to establish trends, predict failure, and measure the life of an asset. Analog Devices has launched CN0549, a condition-based monitoring development kit. The monitoring functionality signifies the consideration for hardware applications involving vibration. The applications include industrial as well as IoT devices. Hence, the CN0549 CBM development board combines the resources for a dynamic domain of users. Discussing further, condition-based monitoring (CBM) through vibration sensing requires the capturing of full-bandwidth data to ensure that all harmonics, aliasing, and other mechanical interactions are taken care of in both, the time and frequency domain. The data collection by using the sensors and data […]
