LILYGO T-Watch S3 Plus smartwatch gets GPS and 940mAh battery

LILYGO T Watch S3 Plus

LILYGO has recently introduced the T-Watch S3 Plus, an ESP32-S3 smartwatch which can be considered an upgrade from the previous generation T-Watch S3, adding a u-blox MIA-M10Q GPS and a larger 940mAh LiPo battery for extended battery life. The T-Watch S3 Plus smartwatch still supports Wi-Fi, Bluetooth LE, and LoRa connectivity, and integrates a 1.54-inch 16-bit full-color TFT LCD display with capacitive touch and a wide-viewing angle. The smartwatch also features an infrared (IR) transmitter that can be used for remote control or proximity detection. T-Watch S3 Plus specifications Wireless MCU – Espressif Systems ESP32-S3 CPU – Dual-Core 32-bit Tensilica LX7 @ up to 240 MHz with vector instructions for AI/ML acceleration Memory – 512KB SRAM, 8MB PSRAM Storage – 16MB flash, 384KB ROM Wireless – Wi-Fi 4 and Bluetooth 5 LE/Mesh Display – 1.54-inch 16-bit full color TFT LCD display with 240×240 resolution, capacitive touch; ST7789V SPI controller Audio – […]

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

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 […]

A LoRa-based Walkie-Talkie? Meet LILYGO T3-S3 MVSR LoRa voice communication kit

LoRa Voice Communication Kit Walkie Talkie

With its low-power, long-range capabilities, LoRa has been used for P2P and Mesh messaging with firmware like MeshTastic, but due to its limited bandwidth, we haven’t seen quite as many LoRa audio applications. This has not stopped LILYGO from designing the T3-S3 MVSR LoRa voice communication kit, integrating LoRa radio, a microphone, and a speaker to use the board as a walkie-talkie solution working over Semtech SX1262 or SX1280 RF transceiver. LILYGO T3-S3 MVSR specifications: SoC – Espressif Systems  ESP32-S3FH4R2 CPU – Dual-core Tensilica LX7 microcontroller @ up to 240 MHz Wireless – 2.4 GHz 802.11n WiFi 4 and Bluetooth 5.0 LE connectivity Memory – 2MB PSRAM Storage – 4MB SPI flash Storage – MicroSD card slot Display – 0.96-inch 128×64 OLED display with SSD1306 I2C driver Audio MAX98357A Speaker MSM261S4030HOR Microphone LoRa module (one or the other) LORA32 SX1262 with 868MHz or 915 MHz radio LoRa 2.4G module based […]

LispDeck handheld lisp computer Runs uLisp on Teensy 4.1 with Wi-Fi, LoRa, and two screens

LispDeck handheld cyberdeck

Designed by Hartmut Graw, the LispDeck is a Handheld Lisp computer built around the Teensy 4.1 microcontroller for Lisp programming on the go. It features a dual-screen setup with a 5-inch touchscreen and, a secondary ST77350-based TFT display. It also has an Adafruit RFM96 radio module, an ESP8266 Wi-Fi module, a rotary encoder, an SD card for storage, and a detachable wireless USB keyboard, all housed in a 3D-printed case. Running the uLisp language, it features a standalone Lisp programming environment without needing a PC or tablet. It is an evolution of the LispBox, with a portable and battery-powered design, which also maintains compatibility. Unlike Raspberry Pi-based cyberdecks, the LispDeck is designed for complete control over the system without the complexity of Linux. It is useful for Lisp enthusiasts who want a compact, dedicated computing device that’s fully documented. LispDeck Specifications SoC – NXP i.MX RT1062 via Teensy 4.1 board […]
