Giveaway Week 2024 winners announced!

We’re now ready to announce the winners of CNX Software’s Giveaway Week 2024. We offered some of the review samples we tested (and some we did not test) in the last year, and for the fourth year running, RAKwireless also gave away two IoT development kits shipped directly to winners. This year’s prizes also included a RISC-V motherboard, a 3D depth camera, a few Arm development boards, two touchscreen displays, and an Alder Lake-N mini PC/router. All those products can be seen in the photo, minus some accessories. You’ll find more than seven devices because we organized the third Giveaway Week on CNX Software Thailand simultaneously with four prizes. We had seven winners on CNX Software: Jupiter RISC-V mini-ITX motherboard – François-Denis, Canada Orbbec Femto mega 3D depth and 4K RGB camera – Reifu, Japan RAKwireless Blues.ONE LoRaWAN, LTE-M, and NB-IoT devkit – OldCrow, Portugal Mixtile Core 3588E development kit […]

It’s already day 6 of CNX Software’s Giveaway Week 2024, and the prize is the Elecrow 7-inch CrowVision touchscreen display designed for Raspberry Pi boards and other single board computers (SBC). Elecrow sent us a sample of the touchscreen display last year to review “whenever we have time”. But it turns out that finding time is tricky, so instead of getting it to waste, I decided to give it away to one lucky reader of CNX Software. Elecrow CrowVision 7-inch display specifications: Type – 7-inch IPS display Resolution – 1024×600 Multitouch – 5-point capacitive touchscreen Viewing angle – 178° Video Input – Mini HDMI connector USB – Micro USB port for touchscreen function Audio 3.5mm audio jack for headphones Speaker connector User input – Touchscreen and keypad interface for provided 5-key board Power Supply 12V/2A DC input via power barrel jack 5V DC output via USB Type-A port Dimensions – […]

CrowView Note Review – A 14-inch laptop shell designed for Raspberry Pi 5 and Jetson Nano Developer kit

Elecrow CrowView Note is a laptop shell with a 14-inch Full HD display, an 84-key QWERTY keyboard with a touchpad, built-in speakers and microphone, and a 5,000 mAh battery that’s specially designed for the Raspberry Pi 5 and the Jetson Nano Developer Kit thanks to adapters. However, it can be used with any machine with either a full-featured USB-C port or spare USB and HDMI ports. So it works with any Raspberry Pi model, Windows, Mac OS, or Linux computers, Android smartphones, PS4/PS5 game consoles, and more. This type of laptop shell has been around for years with the first one being the Laptop shell for the Motorola Atrix 4G smartphone introduced in 2011, and more recently Nexdock launched a range of laptop shells such as the Neckdock XL 15.6-inch touchscreen display and wireless charging. The CrowView Note differentiates itself with its low price and direct compatibility with the Raspberry […]

Review of CrowVi 15.6-inch portable USB-C and HDMI touchscreen display with Windows 11, Ubuntu 24.04, and Raspberry Pi 5

Elecrow CrowVi VF156T – or just CrowVi for shorts – is an ultra-thin 15.6-inch portable touchscreen display with mini HDMI and USB-C input ports making it suitable for a wide range of devices from Windows 11 and Linux mini PCs or laptops, SBCs such as the Raspberry Pi 5, and smartphones featuring a USB-C port with DisplayPort Allt. mode. The display supports 10-point multitouch, offers a 1920×1080 “Full HD” resolution, and includes stereo speakers and a 3.5mm audio jack. Besides the USB-C input, it also comes with an additional USB-C PD port for power in case the host does not provide enough power or only HDMI input is used without the touchscreen function. There’s also a “smart case” acting as a foldable stand on the back so you don’t need to bring your own stand. Elecrow sent us a sample of the CrowVi 15.6-inch portable monitor for review and we […]

Review of Elecrow’s 3.5-inch and 7.0-inch ESP32 display modules using Arduino programming

Using the ESP32 7.0-inch display as a dashboard

Hello, I’m excited to review the ESP32 display modules and HMI touchscreens from Elecrow with sizes ranging from 2.4 to 7.0 inches. For this review, Elecrow kindly provided me with both 3.5-inch and 7.0-inch models. While their screens differ in size, both modules share several components, such as the ESP32 microcontroller, making them adaptable options for a variety of projects. The Elecrow 7.0-inch display module is powered by the ESP32-S3-WROOM-1-N4R8 module equipped with an ESP32-S3 dual-core LX6 32-bit microprocessor, 4 MB of flash, 384 kB of ROM, and 512 kB of SRAM. This microcontroller supports both WiFi and Bluetooth for wireless communication. The 7.0-inch display itself is a capacitive touch screen with a resolution of 800×480 pixels. The display is controlled by the EK9716BD3/EK73002ACGB driver and is compatible with LVGL for additional functionality. In the case of the 3.5-inch display module, the main difference is the use of the ESP32-WROOM-32-N4 […]

ESPHome compatible “Smart Powermeter” supports up to 6 CT clamps

J.G.Aguado’s “Smart Powermeter” is an ESP32-S2 board with a 2.9-inch e-paper display designed to measure power consumption through up to six CT clamps, or Current Transformer clamps, that are each attached to one of the AC lines of a house or appliance. I used an MT87 Digital Clamp Multimeter nearly 10 years ago to easily and safely measure the power consumption of a whole house by simply clamping it on one of the cables outside and reading the results on the display. The Smart Powermeter works in the same way but can perform measurements for up to six devices, and besides seeing the results on the display the ESP32-S2 can also send the data to the cloud or local server for data gathering and analysis using ESPHome or Arduino firmware. Smart Powermeter specifications: Wireless module – ESP32-S2-MINI-1-N4R2 SoC – Espressif ESP32-S2FH4 CPU Single-core 32-bit LX7 microcontroller @ up to 240 […]

Giveaway Week 2023 winners announced!

CNX Software’s Giveaway Week 2023 is now over and we’re ready to announce the winners. We offered some of the review samples we tested (or not) in the last year, and like the last two years, we were also joined by RAKwireless who offered two IoT development kits. All items given away are shown in the photo below, minus some accessories, and if you count more than seven you’d be right, as some are kits with multiple items like the GL.iNet GL-S200 Thread Border router which comes with three development boards, and more importantly, we also organized Giveaway Week on CNX Software Thailand for the second year running. We had seven winners on CNX Software: VOIPAC iMX8M industrial development kit – Kraingsak, Thailand TBS7901 mini PCIe DVB-S2X/S2 module – Frank, Singapore RAKWireless WisBlock IoT Starter Kit – Andy, Russia GL.iNet GL-S200 Thread Border router kit – Augustin, Argentina WCH CH583M-R0-1v1 […]
