Espressif Systems ESP32-P4-EYE development kit looks like a camera

Espressif Systems’ ESP32-P4-EYE is a development kit designed for AI vision applications that looks like a standard camera. It combines an ESP32-P4 RISC-V microcontroller with an ESP32-C6 WiFi 6, BLE, and 802.15.4 SoC, and is equipped with a MIPI-CSI camera, a 2MP display, a microphone, and a MicroSD card to store photos or videos. There’s also a rotatory encoder to control the menu on the LCD or adjust the zoom, a fill/flash light, a few buttons, an LED, and support for either USB or battery power. The company says the ESP32-P4 camera devkit targets smart surveillance, vision-based edge AI, real-time image detection, and audio-visual IoT interfaces.

SONOFF SNZB-02LD and SNZB-02WD IP65-rated Zigbee LCD Smart thermometers work with liquids or outdoors

SONOFF SNZB-02LD IP65 Zigbee LCD Thermometer

ITEAD has introduced two new SONOFF devices: the IP65-rated SNZB-02LD and SNZB-02WD Zigbee 3.0 LCD Smart thermometers designed to work in liquids or enclosed spaces such as bathtubs or refrigerators, or outdoors in gardens or other humid environments, respectively. Both devices look similar and can measure temperature with +/- 0.5°C accuracy, but the SONOFF SNZB-02LD model ships with a 1.5m long probe to measure the temperature of liquids in a pool, a bathtub, or fermentation vessel (for beer or wine making), as well as in refrigerators. On the other end, the SNZB-02WD features a built-in temperature and humidity sensor. SONOFF SNZB-02WD/LD specifications: MCU – Telink TLSR8656F512ET32 (part of the TSL8656 family – See PDF datasheet ) Zigbee/RF4CE SoC with 32-bit RISC MCU, 64kB SRAM, 512kB internal Flash Display – 2.2-inch LCD Wireless – Zibgee 3.0 (802.15.4 radio on TSL8656) Temperature and Humidity sensor SNZB-02WD (internal) Temperature Range – -20°C to […]

Samsung 32″ EMDX color e-paper display runs Tizen 8.0, offers 2560×1440 resolution, up to 200 days of battery life

Samsung 32" EM32DX color E-paper Display

Samsung has unveiled a 32-inch color e-paper display with WQHD (2,560 x 1,440) resolution and a built-in 4,600mAh battery that can last up to 200 days on a charge if the display is updated once a day. The Samsung 32″ EMDX color e-paper display is mainly designed for digital signage applications in shops, restaurants, public transportation, and public spaces. Like other e-paper displays, it does not consume any power if the image is unchanged. I was initially surprised at the bright colors of the EMDX display from the photos shared by Samsung, but after a closer look, I’m not convinced those are photos of the actual display. Samsung 32″ EMDX color e-paper display specifications: 32-inch E-Ink Spectra 6 Color ePaper with 2,544 x 1,400 resolution, up to 54,600 colors with dithering, 178° H/V viewing angle Storage – 8 GB eMMC flash Wireless – WiFi 5 and Bluetooth 5.0 Ethernet – […]

GPMI is a Chinese alternative to HDMI and DisplayPort with up to 192 Gbps bandwidth, 480W Power Delivery

Defined by the Shenzhen 8K UHD Video Industry Cooperation Alliance (SUCA), GPMI (General Purpose Media Interface) is an alternative to HDMI and DisplayPort supporting up to 192 Gbps bandwidth and 480W power delivery (PD). As far as I know, the specifications have not been made public just yet, but ITHome.com shared some photos and details. The GPMI standard defines two types of connectors: Type-B and Type-C (USB-C) with support for 192 Gbps/480W PD and 96 Gbps/240W PD, respectively. Here’s how GPMI compares to the latest HDMI and DP versions. The best resource I’ve found about the GPMI standard is a white paper shared by Hisilicon. It requires email registration, and it’s only in Chinese, but I’ve translated some of the slides for reference. The Type-B port looks like a compressed HDMI port, which might be great for laptops and tablets, while the Type-C port appears to be identical to a […]

Seeed Studio XIAO 7.5″ ePaper panel supports ESPHome firmware, Arduino programming

Seeed Studio XIAO 7.5″ ePaper Panel interfaces an XIAO ESP32-C3 USB-C board and mainly targets the Smart Home market with support for ESPHome, but the monochrome ePaper display is also programmable with the Arduino IDE for a wider range of applications. The display offers a resolution of 800×400 and includes a 2,000mAh battery good for three months per charge with updates every 6 hours. Seeed Studio says the display can operate in the -40°C to 85°C temperature range, so it would be suitable for outdoor use as long as it’s not exposed to rain or dust. The USB-C port of the ESP32-C3 module and the Boot and Reset buttons are easily accessible for charging the display and programming it. XIAO 7.5″ ePaper Panel specifications: Wireless module – XIAO ESP32C3 SoC – Espressif Systems ESP32-C3 CPU – Single-core RISC-V microcontroller @ 160 MHz Memory/Storage – 400KB SRAM, 384KB ROM, 4MB flash […]
