Debashis Das writes that the ZecTrix Note 4 is an ESP32-S3 based smart note featuring a 4.2-inch e-paper display and integrated voice capabilities for managing reminders, weather, and schedules. The device offers both monochrome and four-color variants (Note 4C) and includes built-in hardware such as a microphone, speaker, NFC, and a rechargeable battery.
- Uses Espressif ESP32-S3 SoC with vector extensions for machine learning workloads.
- Features community firmware options like Slate or TransitInk OS to repurpose the device.
- The Note 4C four-color variant is notably cheaper than the monochrome version on the manufacturer's website.
Jean-Luc Aufranc writes that Seeed Studio’s reTerminal Sticky is a 3.97-inch magnetic touch ePaper display powered by an ESP32-S3 microcontroller. This device can serve as an e-reader, live dashboard, or home automation controller via support for open-source firmware like Crosspoint, TRMNL, and ESPHome. It features a capacitive touchscreen and edge computing capabilities through its built-in microphone.
- 800 x 480 resolution with four levels of grayscale
- Includes temperature/humidity sensors and a 3-axis accelerometer
- Equipped with a 750 mAh battery providing approximately seven days of standby time
- Retails for $49.90
Building an affordable Home Assistant dashboard does not require expensive hardware. This guide explores several low-cost methods to create functional control panels and information displays using existing or cheap equipment.
Ways to build a budget dashboard include:
* Repurposing old tablets, phones, or even Kindles from your junk drawer using kiosk browsers or the Home Assistant companion app.
* Purchasing second-hand hardware like older tablets or digital photo frames through online marketplaces.
* Using small ESP32 touchscreen modules for low-power desktop dashboards.
* Implementing E-Ink displays for minimal, always-on information such as weather and calendars.
* Jailbreaking used smart displays to bypass manufacturer limitations and run custom software.
Weather Station designed for the Lilygo T5 4.7 inch Epaper Development Platform. Allows for user-friendly configuration of weather display settings via a web interface.
LILYGO has announced a raft of new microcontroller development boards targeting different niches: a low-frequency LoRa board, an ultra-widescreen display board, a LoRa-equipped ePaper display board, and a CAN bus board. The boards are powered by the Espressif ESP32-S3 microcontroller.
