Giveaway Week 2023 – Elecrow ESP32 Terminal with a 3.5-inch touchscreen display and OV2640 camera

Elecrow ESP32 Terminal giveaway

If I remember correctly, Elecrow sent me an end-of-year gift with a notebook (paper style), a pen, and a 3.5-inch ESP32 terminal. I had completely forgotten about it, and while wondering what I would give for Giveaway Week 2023, and looking around in drawers and on shelves, I found an “ESP32 Terminal” package, and I was like “What the F is that and where is it coming from?”. Long story short, the 6th prize of this year’s giveaway week is Elecrow’s ESP32 Terminal with a 3.5-inch touchscreen display that also comes with a front-facing OV2640 camera and six Crowtail connectors for expansion plus a LiPo battery connector. Elecrow ESP32 terminal specifications: Wireless module – ESP32-S3 2.4 GHz Wi-Fi and Bluetooth 5 (LE) module with 16MB flash and 8MB PSRAM Storage – MicroSD card slot Display – 3.5-inch TFT LCD display with 480×320 resolution (ILI9488 driver), capacitive touchscreen Camera – 2MP […]

ESP32 Arduino Core 3.0.0 adds support for ESP32-C6 and ESP32-H2

ESP32-C6 ESP32-H2 Arduino

Espressif Systems has now released an alpha version of ESP32 Arduino Core 3.0.0 enabling the new ESP32-C6 and ESP32-H2 targets to be programmed with the Arduino IDE, and including a number of new features made possible by the ESP-IDF 5.1 SDK. Announced in 2021, the ESP32-C6 WiFi 6, Bluetooth 5 LE, and 802.15.4 wireless MCU became available in modules and devkits at the beginning of this year, but so far they could only be programmed with the latest version (5.1) of the ESP-IDF framework, and so was the new ESP32-H2 Bluetooth 5.2 and 802.15.4 (Zigbee/Thread) MCU. But fans of Arduino programming can now rejoice as an alpha version of ESP32 Arduino Core 3.0.0 brings support for the new microcontroller, and a stable release is planned for December 2023. But as you can probably imagine ESP32 Arduino Core 3.0.0 will also bring lots of other changes since the ESP32 Arduino Core […]

Review of RaZberry 7 Pro Z-Wave Raspberry Pi HAT and Z-Uno2 Z-Wave board

RaZBerry 7 Pro Z-Uno2 Z-Wave Review

Z-Wave.Me has sent us a couple of Smart Home devices based on Z-Wave technology for review, namely the RaZberry 7 Pro Raspberry Pi HAT and the Z-Uno2 board. The Swiss company has primarily developed Z-Wave products for years and is a member of the Z-Wave Alliance. For those who are concerned about the issues of signal interference in the 2.4GHz range (WiFi, Zigbee, Bluetooth, and Thread), Z-Wave technology is an excellent choice because it operates on a less congested frequency range of 800-900MHz and the technology has been around for more than 20 years, resulting in a wide variety of Z-Wave devices available in the market, and they can work well together across different brands due to a proper certification process which is another advantage when compared to other protocols. The two devices we received are RaZberry 7 Pro, which is a shield that plugs into the 40-pin GPIO header […]

The Portenta Hat Carrier board adds Raspberry Pi HAT support to the Portenta X8 SBC

Arduino Portenta Hat Carrier

The Arduino Portenta Hat Carrier board aims to interface the Linux-capable Portenta X8 board with the vast ecosystem of Raspberry Pi HAT (Hardware on Top) expansion boards. Introduced last year, the Arduino Portenta X8 is the first Arduino Pro hardware that can run Linux thanks to its NXP i.MX 8M Mini Arm Cortex-A53 quad-core processor. But it comes in a tiny 66.04 x 25.4 mm form factor which may be great for integration into products, but for prototyping or design of products such as IoT gateways, the company has now launched the Portenta Hat Carrier that enables the board to easily connect with the Raspberry Pi HATs available today. Portenta Hat Carrier specifications: Compatible with the Portenta X8 board and future Portenta with the same high-density connectors Storage – MicroSD card slot Camera I/F – MIPI CSI camera connector (CNXSoft: Arduino does not explicitly say whether it’s compatible with the […]
