SONOFF SNZB-02D review – A Zigbee temperature & humidity sensor with a 2.5-inch display

Sonoff SNZB-02D review

We’ve previously tested the SNZB-02 Zigbee temperature and humidity sensor with the SONOFF NSPanel Pro smart panel, but ITEAD has now launched the SONOFF SNZB-02D that integrated the same features plus a 2.5-inch display to visualize the data. They’ve sent us a SNZB-02 sample for review, so after listing the specifications we’ll test SONOFF’s latest Zigbee sensor with Home Assistant. SONOFF SNZB-02D specifications Display – 2.5-inch black&white display Connectivity – Zigbee 3.0 Sensors Temperature sensor with -9.9°C to 60°C range, ±0.2°C accuracy Humidity sensor with 5%—95%RH range, ±2%RH accuracy Battery – 3V CR2450 coin-cell battery good for about 2 years with a 5-second polling rate Dimensions – 62.5 x 59.5 x 18.5mm Material – PC Color: White Unboxing and first try We’ll find the sensor in the usual orange package used for Zigbee devices. The SNZB-02D sensor comes with a quick start guide and a pre-installed battery. Just pull the […]

PicoVNA 5 software for vector network analyzers supports Windows, Linux, MacOS, and Raspberry Pi

PicoVNA 108 vector network analyzer

Pico Technology has released PicoVNA 5 control software for their vector network analyzers for Windows x86 64-bit, Mac, Linux x86 64-bit, and Raspberry Pi 3 and greater single board computers, superseding the Windows-only PicoVNA 3 software. As a Ubuntu user, I hate it when some hardware tool forces me to install software on Windows when there’s no Linux alternative, so any company that provides cross-platform tools is making the right move. I’m also not quite sure what a “vector network analyzer” (VNA) is, so I’ll first look into the PicoVNA 106 and PicoVNA 108 6/8.5 GHz VNAs from the company. PicoVNA 106/108 vector network analyzers highlights and specifications: Frequency ranges PicoVNA 106 – 300 kHz to 6 GHz PicoVNA 108 – 300 kHz to 8.5 GHz Up to 5500 dual-port S-parameters per second > 10 000 S11 + S21 per second Quad RX four-receiver architecture Up to 124 dB dynamic […]

ArmSoM CM5 Raspberry Pi CM4 alternative with Rockchip RK3576 SoC

Banana Pi BPI-W3 SBC features Rockchip RK3588 SoM, M.2 NVMe socket, 2.5GbE, HDMI output and input

Banana Pi BPI-W3

Banana Pi BPI-W3 is another Rockchip RK3588 SBC (single board computer) with 8GB RAM, 32GB eMMC flash, an M.2 NVMe socket, 2.5GbE networking, two HDMI 2.1 output ports, one HDMI 2.0 input port, and other features. We first recovered the board last summer, but at the time the RK3588 SBC came with a PCIe x4 slot and dual Gigabit Ethernet, and the company has now redesigned the board without either using instead a Rockchip RK3588 system-on-module as part of the design and implemented 2.5GbE and M.2 NVMe SSD support with the available PCIe interfaces. Banana Pi BPI-W3 specifications: SoM – BPI-RK3588 core board SoC- Rockchip RK3588 octa-core processor with 4x Cortex-A76 cores @ up to 2.4 GHz, 4x Cortex-A55 cores @ 1.8 GHz, an Arm Mali G610MC4 GPU, a 6 TOPS NPU, 8Kp60 H.265/VP9/AVS2 10-bit decoder, 8Kp30 H.265/H.264 encoder System Memory – 8GB LPDDR4 (options for 4GB to 32GB) Storage […]

$60 M5Stack CoreS3 ESP32-S3 IoT controller comes with 2-inch display, VGA camera, multiple sensors

M5Stack CoreS3 ESP32-S3 IoT controller

M5Stack CoreS3 is a battery-powered ESP32-S3 IoT controller with WiFi and Bluetooth connectivity, a 2-inch touchscreen display, a 0.3MP camera, a microSD card slot for storage, several sensors, plenty of I/Os, a USB Type-C OTG port, as well as a 9V to 24V DC input port. That’s the second ESP32-S3 IoT controller from M5Stack we’ve seen this year, as the CoreS3 follows the smaller M5Stack AtomS3 with a 0.85-inch display, only a few I/Os, and fewer features overall although it does come with an IR transmitter that’s missing from the larger CoreS3. M5Stack CoreS3 specifications: Wireless MCU – Espressif Systems ESP32-S3FN16R8 dual-core 32-bit Xtensa LX7 microcontroller with AI vector instructions up to 240MHz, RISC-V ULP co-processor, 512KB SRAM, 2.4GHz WiFi 4 (802.11b/g/n), Bluetooth 5.0 BLE + Mesh, 16MB flash, 8MB PSRAM Antenna – Internal “3D” antenna Storage – MicroSD card slot Display – 2-inch display with 320×240 resolution via ILI9342C […]

Creality Ender-3 S1 Pro review – Part 2: Engraving and 3D printing

Creality Ender 3 S1 Pro 3D Printer laser Engraver

Earlier this year, I received the Creality Ender-3 S1 Pro 2-in-1 3D printer & laser engraver and in the first part of the review, I showed the package content and how to assemble the system either to use it as a 3D printer or a laser engraver, but didn’t start it at the time. I’ve now had time to play with both laser engraving (less luck with cutting) and 3D printing, so I’ll report my experience in the second part of the review. Creality Ender-3 S1 Pro laser engraving Since in the last part of the review I had the 10W laser module installed on the 3D printer, I decided to start the testing with laser engraving and cutting. Contrary to the TwoTrees TS2 laser engraver I reviewed last year, the Creality Ender-3D S1 Pro laser engraving kit does not support autofocus, so I used the provided multi-level fixed-focus bar […]
