It packs a solar panel, 800mAh battery, L76K GNSS module, 0.42-inch OLED display, 9-axis IMU, digital microphone, speaker, and magnetic USB interface into a weatherproof form factor. Connectivity spans Bluetooth 5, NFC, Bluetooth Mesh, Zigbee/Thread, ANT, and LoRaWAN. Arduino firmware and code samples are available on GitHub, and the board supports Meshtastic (firmware merged but not yet in the web flasher) and MeshCore off-grid communication platforms. Priced at $74.98 on AliExpress or $60.31 on the LILYGO store, it costs more than comparable thin trackers like the RAKwireless WisMesh Tag or Seeed Studio T1000-E ($40 each), but adds solar charging, voice capability, and a display. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What wireless chip and LoRa transceiver does the LILYGO T-Echo Card use? The T-Echo Card uses a Nordic Semiconductor nRF52840 wireless MCU (32-bit Arm Cortex-M4F at 64 MHz, 1 MB flash, 256 KB RAM) paired with a Semtech SX1262 LoRa transceiver supporting 400-520 MHz and 830-945 MHz bands. It also includes an L76K GNSS module for GPS, GLONASS, BeiDou, and QZSS positioning with AGNSS support. _Track hardware releases like nRF52840-based LoRa boards as they land on daily.dev._ ### Does the LILYGO T-Echo Card support Meshtastic firmware? Yes, support for the T-Echo Card was merged into the Meshtastic firmware repository, though it isn't yet available in the Meshtastic web flasher, meaning users currently need to build the firmware themselves. Community firmware for the MeshCore off-grid communication project is already available through the MeshCore flasher. _Makers comparing mesh networking firmware options can follow updates like this on daily.dev._ ### How much does the LILYGO T-Echo Card cost compared to other thin LoRa GPS trackers? The T-Echo Card sells for $74.98 on AliExpress (with a USB magnetic cable) or $60.31 on the LILYGO store, more expensive than competitors like the RAKwireless WisMesh Tag and Seeed Studio T1000-E, which both cost $40. The higher price reflects extra features including a solar panel, speaker, microphone, and OLED display absent from the slimmer competitors. _Weighing LoRa tracker options by price and features gets easier following comparisons like this on daily.dev._ ## Similar posts on daily.dev -
