LILYGO T-Deck Pro – An ESP32-S3 LoRa messenger with e-paper touch display, keyboard, and 4G LTE or audio codec option

LILYGO T-Deck Pro is a LoRa messenger based on an ESP32-S3 WiFi 4 and Bluetooth 5.x SoC, and offered with a 3.1-inch e-paper display with touchscreen, a Blackberry-like QWERTY keyboard, a GPS module, speaker, microphone, and a 3.5mm audio, as well as IMU and light sensors. It builds upon the T-Deck Plus design, but replacing the 2.8-inch IPS display with a 3.1-inch e-paper display allows for a slimmer design and should offer longer battery life despite the smaller 1,400 mAh battery used in the new model. Two versions of the T-Deck Pro are available: one with a Simcom 4G LTE modem and a cheaper one with a PCM5102A audio codec. LILYGO T-Deck Pro specifications: SoC – ESP32-S3FN16R8 CPU – Dual-core Tensilica LX7 microcontroller @ up to 240 MHz 2.4 GHz 802.11n WiFi 4 and Bluetooth 5.0 LE connectivity Memory – 8MB PSRAM Storage – 16MB SPI flash Storage – MicroSD card […]

u-blox ZED-X20P all-band GNSS module delivers global centimeter-level accuracy at a 90% lower cost (TCO)

Previously u-blox announced the release of the X20 series of all-band GNSS modules, but at the time, the company did not disclose detailed specifications for the module. Recently, they have launched the ZED-X20P all-band GNSS module designed to deliver centimeter-level global positioning at a significantly lower cost, up to 90% less than traditional solutions when considering the total cost of ownership. The module supports L1, L2, L5, and L6 bands across four GNSS constellations (GPS, Galileo, GLONASS, and BeiDou), along with SBAS, QZSS, and NavIC. Additionally, the module is compatible with PPP-RTK, network RTK, and global PPP correction services, along with u-blox’s PointPerfect and Galileo’s free High Accuracy Service (HAS), ensuring precise and flexible positioning. It also features secure boot, signed firmware, encrypted communication, and anti-jamming capabilities, for critical applications. The ZED-X20P maintains the ZED form factor, making the footprint compatible with the ZED-F9P chip for easier upgrades. u-blox says […]

Solar-powered LLM over Meshtastic solution may provide live-saving instructions during disasters and emergencies

People are trying to run LLMs on all sorts of low-end hardware with often limited usefulness, and when I saw a solar LLM over Meshtastic demo on X, I first laughed. I did not see the reason for it and LoRa hardware is usually really low-end with Meshtastic open-source firmware typically used for off-grid messaging and GPS location sharing. But after thinking more about it, it could prove useful to receive information through mobile devices during disasters where power and internet connectivity can not be taken for granted. Let’s check Colonel Panic’s solution first. The short post only mentions it’s a solar LLM over Meshtastic using M5Stack hardware. On the left, we must have a power bank charge over USB (through a USB solar panel?) with two USB outputs powering a controller and a board on the right. The main controller with a small display and enclosure is an ESP32-powered […]

GoogleFindMyTools locates ESP32-based Bluetooth trackers using Google Find My Device network

Leon Böttger’s GoogleFindMyTools is a re-implementation of Google’s Find My Device network. It works with Android devices and commercial trackers, but experimental support for ESP32-based trackers has recently been added.

The implementation features two components. First, the main.py Python script that will list and locate devices, and then the ESP32 firmware implemented in C with the ESP-IDF. The host computer will also need several Python libraries that can be installed with “pip install -r requirements.txt” and Google Chrome web browser.

This is the output of the Python script on my Ubuntu laptop:
