Embedded and hobbyist electronics specialist LILYGO has launched a brand new, extra compact tackle its LoRa- and ePaper-equipped T-Echo all-in-one improvement board: the T-Echo Lite, now obtainable in a extra modular format.
“The T-Echo Lite is a light-weight model of the T-Echo, designed with a low-power mixture of LoRa, [Nordic Semiconductor] nRF52840, and an ePaper show, making it an optimum resolution for ultra-low energy LoRa functions,” the corporate writes of its new launch. “It’s absolutely appropriate with Meshtastic firmware, offering dependable long-range wi-fi communication.”

LILYGO launched the unique T-Echo again in June 2021, itself a follow-up to the sooner T-Beam. The design mixed a Nordic nRF52840 microcontroller with a Semtech SX1262 LoRa transceiver and a 1.54″ low-power ePaper show. A 3D-printed housing with squat omnidirectional antenna accomplished the design, whereas an inside battery made it appropriate for area use — and the gadget proved in style for these working with the community-driven Meshtastic mesh networking mission.
The T-Echo Lite, dropped at our consideration by CNX Software program, is far the identical as its predecessor, packing a Nordic nRF52840, Semtech SX1262, and TDK InvenSense ICM20948 nine-axis inertial measurement unit (IMU) behind a smaller 1.22″ ePaper show. The exterior antenna is lacking, although, and so is the interior battery; as an alternative, the extra compact system options connectors on its rear for an optionally available battery, photo voltaic panel, International Navigation Satellite tv for pc System (GNSS) module, and to offer entry to unused general-purpose enter/output (GPIO) pins, with a pair of Qwiic growth headers and a USB Sort-C port for knowledge and energy to the aspect.

The design can be extra modular than its predecessor: a “Core” module, which options the microcontroller and LoRa transceiver plus energy administration, connects to a “Base” service that then installs contained in the “Fundamental Unit” housing with show. Whereas the “Fundamental Unit” configuration is more likely to show the most well-liked, LILYGO can be promoting the “Base” service board and “Core” module individually for individuals who’d prefer to roll their very own resolution.
The T-Echo Lite has been listed on LILYGO’s AliExpress retailer, beginning at $16.18 for the Core module and rising to $40.98 for the complete Fundamental Unit bundle with GPS module; on the time of writing, nevertheless, delivery to the US was unavailable, and the system has but to seem on LILYGO’s personal web site.
