STMicro adds more STM32U5 Cortex-M33 MCUs with NeoChrom 2.5D GPU, 128KB to 4MB flash, NIST certification, etc…

STMicro has added three new families to its STM32U5 Cortex-M33 microcontroller series with the entry-level STM32U535/545 with as little as 128KB flash, the STM32U595/5A5 with up to 4MB of Flash and 2,514KB of RAM, and the STM32U599/5A9 with similar features as the STM32U595/5A5 by adding the new NeoChrom 2.5D GPU plus TFT-LCD and DSI display interfaces. STMicro also announced that STM32U5 series MCUs were the first general-purpose MCUs to receive NIST-embedded random-number entropy source certification. As of now, along with the STM32U575/585 introduced in February 2021 with an optional Chrom-ART 2D GPU, STMicro offers eight product lines as part of the STM32U5 MCU series as shown in the table below. That means the STM32U5 microcontroller can address a wider range of applications with the STM32U535/545 targetting lower-cost applications with less flash and RAM, the “legacy” STM32U575/U585 for mid-range applications, and the STM32U59X/5AX for applications where more storage and memory is […]

Control 8 relays with the Raspberry Pi Pico using PicoRelay8 or Pico-Relay-B

Waveshare Pico Relay B with Raspberry Pi Pico board

8086 Consultancy’s PicoRelay8 is a baseboard for the Raspberry Pi Pico (W) board equipped with eight 28V DC / 10A Normally Open relays that be used for all sorts of automation projects, while Waveshare Pico-Relay-B also supports eight relays with both DC and AC loads and comes with some extra features. PicoRelay8 PicoRelay8 board specifications: Supported MCU board – Raspberry Pi Pico or Pi Pico W, and it may also work with “mostly” compatible boards such as the Banana Pi BPI-Pico-RP2040 or BPI-PicoW-S3, WeAct RP2040, and others as long as all GPIO used on the PicoRelay8 are exposed on the same pins. Relays 8x HF3FF/005-1HST relays rated for 28V DC/10A, as well as 10A/250V AC and 15A/125V AC, but the board is not designed to get power from the mains (safety-wise), so it’s only really suitable for DC loads Each relay has a 2-pin terminal block attached to it. GPIO […]

ESP32 OpenMQTTGateway smart plug acts as an BLE MQTT gateway and a power meter

The Theengs Plug ESP32 smart plug runs OpenMQTTGateway firmware to serve as a BLE MQTT gateway and power meter compatible with Home Assistant, Homebridge, OpenHAB, DomoticZ, FHEM, Jeedom, NodeRed, AWS, and any MQTT-compatible IoT or Smart Home system. While the Matter standard should improve interoperability between Smart Home frameworks over time, there are still millions of devices already produced that are not Matter compatible, and the Theengs Plug aims to at least partially address this issue by helping users reduce the number of hubs required and have only one that supports different ecosystems. Theengs Plug hardware specifications: Microcontroller – ESP32 dual-core wireless MCU with 2.4 GHz WiFi and Bluetooth LE connectivity Network Protocol – MQTT Power Supply – 100-120VAC, 60Hz, up to 15A Dimensions – 103 x 61 x 34.6mm Temperature Range – Operating: 0ºC ~ 40ºC; storage: -10°C ~ 50°C Humidity – 0%～95% (no condensation) Certification – UL Some […]
