ZigUNO – An Arduino UNO-sized Zigbee board that works with PTVO firmware

ZigUNO Zigbee development board comes with an Ebyte E18-MS1 module equipped with Texas Instruments SimpleLink CC2530 8051 Zigbee microcontroller and follows Arduino UNO form for Arduino Shield compatibility. The board works with PTVO Zigbee firmware that comes with a graphical configuration tool to select the Zigbee chip used (CC2530), configure I/O behavior (input/output, pull-up, etc…), and more. The developers also suggest using DIYRuZ projects as examples to get started. ZigUNO board specifications: Zigbee module – Ebyte E18-MS1-PCB module with TI SimpleLink CC2530 8051 microcontroller with Zigbee 3.0 (and IEEE 802.15.4) connectivity, 256kB Flash and 8kB RAM, PCB antenna Expansion – Arduino UNO headers (3.3V only, not 5V tolerant) Power Supply – 5V up to 1.5A via 5.5/2.1mm DC jack, 2-pin terminal block, or micro USB port Dimensions – 82x54x13 (Arduino UNO form factor) Temperature Range – 0 to 50°C You’ll find the hardware design files including EasyEDA PDF schematics, BoM, […]

Raspberry Pi Pico W – A $6 Raspberry Pi Pico board with WiFi 4

I was expecting the next official Raspberry Pi board to be either an update of Raspberry Pico with WiFi and Bluetooth or with a machine learning accelerator and the new $6 Raspberry Pi Pico W delivers that wish through the addition of 2.4GHz WiFi 4. Having said that, I was actually expecting a competitor to ESP8266 or ESP32 with a new Raspberry Pi wireless microcontroller, but it did quite happen that way as the Raspberry Pi Pico W features the same Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller found in Raspberry Pi Pico board coupled with an Infineon CYW43439 chip that’s supposed to support both 2.4 GHz WiFi 4 and Bluetooth LE 5.2. Bluetooth is not enabled right now, but may be at a later stage. Raspberry Pi Pico W specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ 133 MHz with 264KB SRAM Storage – 2MB QSPI flash Connectivity […]

NORVI GSM industrial controller with WiFi and cellular connectivity supports Arduino or ESP-IDF programming

We’ve already seen ESP32 WiFI & Bluetooth SoC combined with a cellular modem several times already, and a couple of days ago, I wrote about LILYGO T-A7068X ESP23 board with a 4G LTE modem. Iconic Devices team has made another cellular ESP32 product with the NORVI GSM industrial controller. The DIN-Rail mountable USB programmable controller is offered with a choice of SIMCOM SIM800L 2G-only modem or QUECTEL EC21-G modem adding 3G UMTS/HSPDA+ and 4G LTE cellular connectivity. It also offers Ethernet connectivity, digital and analog inputs, relay outputs, and a small 0.96-inch OLED information display with options varying depending on the exact model. NORVI GSM specifications: Main module – ESP32-WROOM-32 with ESP32-D0WDQ6 dual-core microcontroller @ up to 160 MHz with 520 KB SRAM, 4 MB flash, 2.4 GHz WiFi 4 and Bluetooth 4.2 connectivity Cellular module (one or the other) SIMCom SIM800L quad-band GSM/GPRS module Quectel E21-G worldwide 4G LTE, […]

Arm Immortalis-G715 GPU supports hardware-based ray tracing

Arm has unveiled the new Immortalis family of flagship GPUs with support for hardware-based ray tracing starting with the Immortalis-G715 GPU, as well as two new premium Mali GPUs namely Arm Mali-G615 and Mali-G715. Software-based ray tracing was already implemented on Arm Mali G710 on SoC’s such as the MediaTek Dimensity 9000, but the hardware-based ray tracing in the Immortalis-G715 delivers over 300 percent performance improvements, and only uses 4% of the shader core area. This will be mostly used in games to generate realistic lighting and shadows as can be seen in the “before vs after” video demo below.   While hardware-based ray tracing is only available on the Immortalis-G715 GPU, all three new GPUs feature a new execution engine and support variable rate shading. The Immortalis-G715 flagship GPU will come with 10 or more cores, the Mali-G715 with 6 to 9 cores, and the Mali-G615 with 6 cores […]

KEEN Ranger PT 4G LTE camera supports animal and human detection

I’ve tested a few security cameras with human and vehicle detection capabilities, but Reolink has now added animal detection via the KEEN Ranger PT trail camera mostly designed to monitor four-legged animals in the wild. It’s somewhat similar to the Reolink Go Plus 4G camera with solar power support and 4G LTE connectivity, but also offers a 360° view with pan/tilt control, a low-glow IR night vision, a 0.5s fast trigger speed, as well as GPS to track the position of cameras or sightings of animals on the mobile app. KEEN Ranger PT camera key features and specifications: Camera/Video Image Sensor – 1/3″ CMOS Sensor Video Resolution – 2K 4MP high definition (2560 x 1440 @ 15FPS) Video Format – H.265 Lens –  f= 2.8mm fixed, F=1.6 Field of View – Horizontal: 95°, vertical: 57°, diagonal: 115° Infrared Night Vision – 12x 940nm no-glow IR LED’s Night Vision Range – […]

DevTerm portable Linux terminal now supports Raspberry Pi CM4 via a $19 adapter

DevTerm modular, portable Linux terminal initially designed for modules based on Raspberry Pi CM3 form factor, can now work with Raspberry Pi CM4 for extra performance and memory thanks to a $19  adapter. The Devterm was initially launched in 2020 with a 6.8-inch IPS screen, a keyboard with 67 keys, and a battery module, all connected through the ClockworkPi v3.14 carrier board taking a choice of core modules based on Allwinner H6 or Rockchip RK3399 (now supported in Armbian), besides the Raspberry Pi Compute Module 3 mentioned above. More recently, it also got an Allwinner D1 RISC-V module. The Raspberry Pi CM4 module should bring performance similar to the Rockchip RK3399 module for most tasks, although it may vary a lot depending on workloads, and for regular Raspberry Pi users, software that will be more familiar, and may be better supported. I’ve just a bit surprised it took so long, […]
