Batteryless 7.5-inch NFC-powered e-paper display V2 gets new NFC chip and “fast flashing method”

Back in 2020, we wrote about Waveshare’s Batteryless NFC e-paper display, which can work without a battery and draws power and data from an NFC-enabled smartphone or the company’s ST25R3911B NFC board. Waveshare has now released a V2 version of this display with a new and improved NFC chip, a “fast flashing method”, and enhanced contrast. The new batteryless, 7.5-inch NFC-powered e-paper display features an 800×480 resolution and updates via an NFC-enabled smartphone or reader. It offers a 170° viewing angle and comes in a durable ABS plastic shell. The ST25R3911B NFC board allows updates via USB, SD card, or serial port, with an optional password lock. However, precise NFC positioning is required for updates. These features make it ideal for shelf labels, equipment tags, and other applications.

BANDIT PC32 standalone ColorForth keyboard computer is powered by the Raspberry Pi RP2350 microcontroller

BANDIT PC32 is a Raspberry Pi RP2350-powered keyboard computer that runs a graphically-oriented version of the ColorForth programming environment. The BANDIT PC32 is primarily aimed at on-the-go use for programming video games. The custom, 32-key split keyboard takes up most of the build, with a 3.2-inch 320 x 240 capacitive display in the center. It also features an HDMI port for connecting a larger external display. The 48-pin GPIO is divided into two female headers and can be used to interface with other devices directly. This is the second version of the Bandit standalone computer, building on an early prototype based on the RP2040 microcontroller. We have seen several interesting RP2350-based products like the Inky Frame 7.3”, 4D Systems display modules, and Jumperless V5 programmable breadboard. However, this is the first RP2350 standalone computer we have come across. It shares some similarities with the ESP32 Rainbow. BANDIT PC32 ColorForth specifications: […]

Wi-Fi 8 (802.11bn) to focus on reliability and efficiency while maintaining Wi-Fi 7 performance

Wi-Fi 7 (802.11be) routers and modules have only been launched recently, but engineers are already working on Wi-Fi 8 (802.11bn) “Ultra High Reliability (UHR)”, and MediaTek shared some details in a whitepaper detailing some of the improvements of the new standard for its upcoming Filogic Wi-Fi 8 SoCs. Surprisingly, there aren’t any enhancements to the maximum performance with Wi-Fi 8 still offering up to 320 MHz channel bandwidth, 23 Gbps maximum PHY rate, and support for 2.4 GHz, 5GHz, and 6GHz frequency bands, as well as up to 8 spatial streams. The Wi-Fi 8 improvements are all meant to improve Wi-Fi reliability, network efficiency, and power consumption in IoT use cases, which will end up improving the overall WLAN performance when many nodes are connected. Wi-Fi 8 new features: Coordinated Target Wait Time (TWT) allows low-power IoT devices to negotiate specific times for transmission with access points in order to […]

LILYGO T3S3 E-Paper combines ESP32-S3 WiFi & BLE SoC with LoRa module, 2.13-inch e-Paper display

LILYGO T3S3 E-Paper is an ESP32-S3 WiFi and Bluetooth LE development board with a 2.13-inch e-Paper display and an SX1262 LoRa module that should make it suitable for off-grid messsaging even under sunlight. LILYGO has made some ESP32-S3 boards with an e-Paper display and some ESP32-S3 boards with a LoRa module, but unless I’m mistaken, the T3S3 E-Paper is the first board from LILYGO that combines ESP32-S3 SoC with e-Paper display and a LoRa module. It builds upon the earlier LILYGO T3S3 board with a 0.96-inch OLED. LILYGO T3S3 E-Paper specifications: ESP32-S3-WROOM-1U wireless module SoC –  ESP32-S3FH4R2 dual-core Tensilica LX7 microcontroller @ up to 240 MHz with 2.4 GHz 802.11n WiFi 4 and Bluetooth 5.0 LE connectivity Memory – 2MB PSRAM Storage – 4MB SPI flash IPEX antenna connector Storage – MicroSD card slot Display – 2.13-inch e-Paper display (DEPG0213BN) with 250×122 resolution; size: 48.55 x 23.70mm Wireless 2.4 GHz […]

Inkplate 6 MOTION STM32-powered wireless e-paper display offers higher resolution and faster refresh rates (Crowdfunding)

The Inkplate 6 MOTION is a new product from Soldered Electronics in their Inkplate series of wireless e-paper displays. It is a 6-inch e-paper display with a partial refresh rate of 11fps which reduces obvious latency in rendering dynamic content such as videos, animations, and scrolling text. The display is driven by an STMicroelectronics dual-core STM32H743 microcontroller, with an ESP32-C3 as a secondary processor. It features Wi-Fi and Bluetooth for networking and a host of peripheral interfaces for physical connectivity. It includes several sensors such as a rotary encoder for quick navigation, a gravitational accelerometer with a gyroscope for tracking device orientation, and a motion detection sensor. We covered the original Inkplate 6 display when it launched on Crowd Supply in 2019. The Inkplate 6 is much less expensive than the new model but has a lower screen resolution (800 x 600 px) and slower refresh rates (256ms). Furthermore, it […]
