CNXSoft: This is a guest post by Florian Robert (1technophile) of the OpenMQTTGateway project about using a 433 MHz LoRa transceiver on an ESP32 board for home automation, specifically to talk to 433 MHz sensors Everyone is talking about Matter, Bluetooth, Zigbee, and Zwave, but before these complex communication technologies, we had one simple, robust one that our sensors and devices used to leverage: 433MHz. It may be too simplistic to talk about 433 MHz as a technology as there are different and various usages of this frequency. You can find it being used in numerous devices around your home, from your outdoor temperature sensors, and security sensors to the tire pressure sensors in your car. If we want to be specific, we can talk about the different radio frequencies (433 MHz, 915MHz, 868MHz, 315MHz, or 350MHz) and signal modulations OOK, ASK, FSK that we encounter behind the keyword 433MHz. [...] The post 433 MHz is not dead! Using an ESP32 board with LoRa module to talk to 433 MHz sensors appeared first on CNX Software - Embedded Systems News. View the full article

Renesas Electronics RL78/G15 is an entry-level 8-bit microcontroller with 1 KB of SRAM, 4 or 8KB of code flash memory, and offered in package sizes ranging from 8 to 20 pins, down to an 8-pin device measuring just 3×3 mm. STMicro has just unveiled the STM32C0 32-bit microcontroller claiming “your next 8-bit MCU is a 32-bit” with packages from 8- to 48-pins and packages as small as 1.70 x 1.42 mm and 3x3mm, and a price similar to other 8-bit industrial microcontrollers. To that, I say “not so fast STMicro!”, as Renesas has just launched the 16 MHz RL78/G15 8-bit microcontroller family with many of the same features and target use cases as the STMC32C011 sub-family. Renesas RL78/G15 key features and specifications: CPU core – Renesas RL78 8-bit core @ up to 16 MHz Memory – 1NS SRAM, Storage – 4 to 8KB program flash, 1KB data flash Peripheral I/F [...] The post Renesas RL78/G15 8-bit MCU is offered in a 3x3mm package appeared first on CNX Software - Embedded Systems News.

8-bit MCUs are still found in many designs, but with the new low-cost 48MHz STM32C0 32-bit Arm Cortex-M0+ microcontroller, STMicrocontroller aims to displace 8-bit microcontrollers thanks to “a limited impact on the cost structure” and the improved support provided by the STM32 ecosystem. The cheapest ever STM32 microcontroller offers up to 32 KB flash, 6 or 12 KB RAM, and I/O interfaces such as UART, I2C, SPI, 12-bit ADC, and so on. The STM32C0 MCUs are available in 8- to 48-pin packages such as WLCSP12, UFQFPN, and the ridiculously tiny 3×3 mm UFQFPN20 package. STMicro STM32C0 key features and specifications: MCU Core -Arm 32-bit Cortex-M0+ CPU @ up to 48 MHz Memory – 6KB (STM32C011x4/x6) or 12KB (STM32C031x4/x6) SRAM with HW parity check Storage – 32KB flash with protection Peripheral interfaces Up to 45x fast I/Os some of which are 5V tolerant; Note: up to 18x fast I/Os for STM32C011x4/x6 [...] The post Low-cost STM32C0 32-bit microcontroller aims to displace 8-bit MCUs appeared first on CNX Software - Embedded Systems News.

Espressif Systems has finally launched the ESP32-W6 WiFi 6, Bluetooth 5.0 LE, and 802.15.4 IoT microcontroller by making the ESP32-C6-WROOM-1 module available on Aliexpress for $14.25 as well as the ESP32-C6-DevKitC-1 development board that’s out of stock on the official store at the time of writing. but somehow listed in another store for $16.22 plus shipping. Besides the availability announcement, another surprise is the 802.15.4 radio for Zigbee and Thread that was not part of the original ESP32-C6 announcement in April 2021. The ESP32-C6-DevKitC-1 development board comes with a module with 8MB flash, exposes most of the I/O’s from the ESP32-C3, and comes with two USB-C ports, two buttons, and an RGB LED.

Creality Ender-3 S1 Pro is a 3D printer that can be converted into a laser engraver thanks to a choice of 1.6W, 5W, and 10W laser modules, making it in theory a space-saving machine that can print 3D objects and engrave & cut materials. The company sent me a full kit with a 10W laser module, so after looking at the 3D printer’s specifications, I’ll check the various packages, and report my experience assembling the 3D printer, and then converting it into a laser engraver in this article, before actually testing both functions in the second part of the review. Since Karl reviewed the Ender-3 Pro 3D printer over two years ago, I asked about the difference and was told the new model got various improvements such as a direct extruder, CR-Touch auto bed-leveling, and support for high-temperature printing.

ROCK Robotic has announced the ROCK Base triple-band multi-constellation RTK/GNSS base station that works with the Web3 GEODNET decentralized GNSS reference network, with the solution designed to offer centimeter accuracy to support applications such as civil surveying, high-definition mapping, digital twin creation, and robotic solutions. Real-time Kinematic (RTK) is a relative positioning technique relying on GNSS (GPS, Galileo, GLONASS, Beidou …) and allowing centimeter positioning accuracy. The technique requires an RTK “Base station” like the ROCK Base and a lower-cost “Rover station” typically attached to a vehicle or drone. For higher accuracy, it’s also possible to use a Network RTK: Network RTK is based on the use of several widely spaced permanent stations. Data from reference stations is combined in a common data processing in a control center. The control center computes corrections for the spatially correlated errors within the network. These corrections are transmitted to the rover. Comparing to [...] The post ROCK Base triple-frequency RTK/GNSS base station works with Web3 GEODNET decentralized network appeared first on CNX Software - Embedded Systems News.
