Reolink Argus PT Ultra review – A solar powered 4K WiFi Pan-and-Tilt smart security camera

Reolink Argus PT Ultra Solar Panel Instllation

Nearly four years ago, I reviewed the solar-powered Reolink Argus PT pan-and-tilt security camera. The device worked (and still works) mostly fine, but it was at a time when security cameras did not implement AI features like people and vehicle detection just yet relying only on PIR motion sensors so I’d get plenty of false positives. The WiFi connection is not overly reliable either especially when I tried to access the camera from outside my house, something that does not happen with the PoE and 4G LTE models from the company. Reolink asked me whether I wanted to review the new Reolink Argus PT Ultra security camera with higher 4K resolution, dual-band WiFi support, as well as people, vehicle, and pet detection, and most of the same other features found on the older Argus PT. So I took up on the offer and I’ve used it for about one month […]

Emporia Vue Gen 2 energy monitor ships with 16 CT clamps, supports single and three-phase power

Emporia Vue

We’ve just written about the “Smart Powermeter” measuring the power consumption of AC appliances through six CT clamps and running either ESPHome or Arduino firmware on ESP32-S3 WiFi and Bluetooth microcontroller. Some people asked about tri-phase and having more CT clamps. One of the commenters then recommended readers to look at the Emporia Vue energy monitor that ships with 16 CT clamps for individual devices/rooms, two 200A CT clamps for whole house monitoring, and supports single-phase up to 240VAC line-neutral, single, split-phase 120/240VAC, and three-phase up to 415Y/240VAC (no Delta). So let’s do that now.   Emporia Vue Gen 2 specifications: Connectivity – 2.4 GHz WiFi 4 Probes 2x 200A current sensors for service mains; 3.5mm plug; dimensions: 65 x 44 x 41mm 16x 50A current sensors to individually monitor air conditioner, furnace, water heater, washer, dryer, range, etc; 2.5mm plug, dimensions: 41 x 23 x 26; accurate from ±2% […]

Watch ESP32’s GPIO status in real-time in a web browser

GPIOViewer ESP32 GPIO web browser

GPIOViewer is an open-source Arduino library allowing users to monitor the GPIO pins status of their ESP32 board in real-time in a web browser for troubleshooting or fun. It’s different than the Wokwi ESP32 simulator that works entirely in a web browser since the GPIOViewer library sends GPIO status data of the actual hardware over WiFi to display the pin status as they change in a page rendered in a web browser from a choice of popular ESP32 development boards. The GPIOViewer library relies on the ESPAsyncWebServer Async web server for ESP8266 and ESP32 and the AsyncTCP asynchronous TCP library for ESP32 microcontrollers. The first two must be manually downloaded and installed, and the latter can be installed directly from the Arduino IDE’s Library Manager by searching for it. GPIOViewer has a 50 KB footprint, works with digital, analog, and PWM, and supports various ESP32-VROOM-32 development boards, Olimex ESP32-EVB and […]

Review of Blackview MP80 (Processor N97) mini PC with Windows 11 Pro

Review Blackview MP80 Processor N97

Blackview MP80 is a tiny pocket-sized mini PC powered by either an Intel Alder Lake-N Processor N95 or Processor N97 CPU with 16GB LPDDR5 RAM and a 512GB M.2 SSD preloaded with Windows 11 Pro. We’ve already reviewed the Blackview MP80 (N95) mini PC a few months ago, but the company has now sent us the Processor N97 model for review. Both models look identical with the same ports including three HDMI 2.0 video outputs, three USB ports, and two gigabit Ethernet ports, plus a Wi-Fi 5 and Bluetooth 4.2 wireless module. The mini PCs are also actively cooled, and the only obvious differences are the processor (Intel N95 vs N97) and the color of the enclosure. We usually do a three-part review with the first one listing the specs, and going through an unboxing and a teardown, but for the Blackview MP80 (N97) review we will do those and […]

MEMENTO is an ESP32-S3-based, CircuitPython or Arduino programmable DIY camera module

Adafruit MEMENTO ESP32 S3

Adafruit’s new MEMENTO – Bare Board Camera module is powered by the ESP32-S3 and can be programmed with CircuitPython or Arduino. The module includes a camera with an OV5640 sensor which features auto-focus capabilities and the board includes a 1.54″ 240×240 Color TFT to display the images. Previously we have covered many ESP32-based camera modules like the TinyML-CAM, the Arduino Nicla Vision, TTGO T-Camera, and many other camera modules that feature the OV5640 sensor you can check those out if interested. Features and Specifications of the MEMENTO ESP32 Camera Module: Processing and Connectivity ESP32-S3 Module Dual-core 240MHz Tensilica processor 8 MB Flash, 2 MB PSRAM WiFi and BTLE capabilities Camera and Display OV5640 Camera Module 5MP sensor 72-degree view Autofocus JPEG encoder 1.54″ Color TFT Display with 240×240 resolution Storage – MicroSD card slot (SPI) Ports and Expansion Two Digital/Analog Stemma Ports – JST PH-3 connectors for A0, A1, power, […]

ODROID-M1S review – Part 1: Ubuntu 20.04, Vu8S touchscreen display, UPS Kit, and WiFi Module 5BK

ODROID-M1S review with UPS module and V8uS module

Hardkernel ODROID-M1S single board board was recently launched to celebrate the company’s 15th anniversary. While the ODROID-M1 board was introduced with the Rockchip RK3568 SoC last year, the new ODROID-M1S board is smaller and cheaper starting at just $49 and comes with a Rockchip RK3566 SoC. Hardkernel sent us a sample of the ODROID-M1S board for review with 8GB of memory and 64GB of storage as well as accessories. Let’s unpack the box before trying it out with Ubuntu 20.04 Desktop and testing each accessory. ODROID-M1S unboxing with ODROID-Vu8S display, UPS kit, and WiFi dongle The review package we received from Hardkernel included the ORDROID-M1S SBC in its plastic enclosure, the VU8S 8-inch touchscreen display, a UPS board, and a dual-band WiFi 5 USB dongle. The UPS module comes without a battery, so we had to find an 18650 battery to use it. As we’ll see further below, the UPS […]

ESP32 Qwiic Pro Mini is an ESP32 board in Arduino Pro Mini form factor

Sparkfun's latest development board puts Espressif ESP32-PICO-MINI-02 on a compact Arduino Pro Mini footprint. It also includes an onboard QWICC connector for easy interfacing with a wide range of sensors and peripherals,

SparkFun’s latest development board, the ESP32 Qwiic Pro Mini, puts the Espressif ESP32-PICO-MINI-02 on a compact Arduino Pro Mini footprint. It also includes an onboard QWICC connector for easy interfacing with a wide range of sensors and peripherals. We have already covered other Sparkfun dev boards like DataLogger IoT, Datalogger IoT – 9DoF, and SparkFun Thing Plus Matter you can check those out if interested. Like any other ESP32 board, this also uses an ESP32 microcontroller which features a 32-bit dual-core processor, 520kB of SRAM, 2MB of PSRAM, 8MB of flash memory, and 16 kB of additional SRAM in its RTC. It supports Bluetooth 4.2 and BLE and has ADC and DAC, touch detection, PWM, TWAI, Ethernet MAC, UART, SPI, SDIO, I2C, and I2S interfaces. As reported in a Hackster article, the board also features a Qwiic Connector for solderless connections to sensor boards and add-ons, positioned at a 90-degree angle […]

Microflex MCUs – Tiny USB development boards based on ESP32-S3, ESP32-S2, ESP32-C3, ESP32-C6, or Raspberry Pi RP2040 (Crowdfunding)

Microflex MCU board with ESP32 and RP2040 microcontrollers

SB Components is back with yet another crowdfunding campaign this time with the Microflex MCUs USB development boards all with the same tiny form factor and offered with a choice of five microcontrollers namely Raspberry Pi RP2040, ESP32-S3, ESP32-S2, ESP32-C3, or ESP32-C6. Microflex MCUs share the same layout with a USB-C port for power and programming, a built-in RGB LED, two buttons for Boot and Reset/User, and two rows of 10-pin with through and castellated holes to access the GPIOs and power signals such as 5V, 3.3V, and GND. But they differ in terms of the processor used, wireless features, and available I/Os as shown in the table below which sadly lacks any information about the flash and eventual PSRAM… The illustration below includes some more details for the Micro-C6 with the main components, ports, and a pinout diagram. Programming the firmware for the ESP32-series can be done through the […]
