LILYGO T-Echo Lite – A 1.22-inch e-Paper display board with nRF52840 SoC, LoRa transceiver, GPS

LILYGO T-Echo Lite

LILYGO T-Echo Lite is a small Nordic Semi nRF52840 board with a 1.22-inch e-Paper display, a Semtech SX1262 LoRa transceiver, and an L76K GPS module, that’s especially suitable for Meshtastic off-grid messaging firmware. It looks like it could even serve as the base for a Meshtastic watch. The T-Echo Lite is a lightweight version of the earlier T-Echo that ships with a larger 1.54-inch e-paper display. Three Lite versions are available: T-Echo Lite Core – Castellated module with nRF52840, LoRa, power, and battery management T-Echo Lite Base – A breakout board for the Core module with battery and solar panel connectors, Qwiic connector, USB port, an interface for a 1.22-inch e-paper display, and an optional GPS expansion header T-Echo Lite Main Unit – Complete solution built around the Base version, a 1.22-inch e-paper display, and an acrylic enclosure. The L76K GPS module is still an option. T-Echo Lite specifications: LILYGO […]

SenseCAP Solar Node P1 and P1-Pro are low-cost outdoor Meshtastic repeaters

SenseCAP Solar Node P1 P1 ProMeshtastic Repeaters

Solar-powered WisMesh Repeaters extend the range of Meshtastic networks

Solar Powered WisMesh Meshtastic Repeaters

RAKWireless has launched two solar-powered Meshtastic range extenders/repeaters: the WisMesh Repeater with a larger battery and external solar panel, and the WisMesh Repeater Mini with a more compact design with an integrated solar panel Meshtastic open-source firmware allows LoRa nodes to be used for off-grid messaging, GPS coordinates sharing, and more. The mesh network relies on nodes to communicate with each other and relay messages to other nodes if needed. However, this does not work reliably when nodes are too far apart or one node goes offline for whatever reason. That’s when Meshtastic repeaters are needed. WisMesh Repeater / Repeater Mini specifications: WisBlock RAK4631 Core Module Wireless SoC – Nordic Semi nRF52840 Cortex-M4F MCU @ 64 MHz with 1MB flash, 256 KB RAM, BLE 5.0, pre-flashed with Meshtastic firmware LoRa transceiver – Semtech SX126x series with support for Meshtastic 8xx and 9xx MHz networks 800 MHz – RU864/ IN865/ EU868 […]

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.
