SoftRF T-Echo NRF52840 LoRa SX1262 868MHz Wireless Module L76K GPS 1.54 E-Paper BME280 Sensor

Description de SoftRF T-Echo NRF52840 LoRa SX1262 868MHz Wireless Module L76K GPS 1.54 E-Paper BME280 Sensor

Application scenarios: DIY creation, LoRa networking, GPS positioning, IOT terminal controlle, Stem education product.
Multi-satellite positioning system L76K is a support multi-satellite system (GPS, BeiDou, GLONASS, QZSS), multi-system joint positioning and single system independent positioning, support AGNSS function, built-in low noise amplifier and surface filter, can provide users GNSS module with fast, accurate and high-performance positioning experience.
Compared with a single GPS system, the high-precision positioning multi-satellite system greatly increases the number of visible and usable satellites, improves positioning accuracy, and can achieve stable high-precision positioning even in complex urban environments.
The display uses a 1.54-inch electronic paper display with front light, 200x200 resolution 1.54 front LED E-paper, and it can be used in a dark environment.

It supports the AGNSS function, which can greatly Reduce the for the first positioning, built-in low-noise amplifier, can achieve high sensitivity, high-precision positioning and fast signal capture and tracking, even under weak signal conditions can also ensure a good positioning performance, built-in surface acoustic filter, can greatly The anti-interference ability of the module is enhanced, and the active antenna detection circuit and protection circuit are integrated inside to protect the module and the active antenna from damage.
T-Echo Introduce:
At the beginning of the design, more consideration was to adapt to Meshtastic and SoftRF, so and low power consumption were considered when designing, and NRF52840 Advanced 5 was selected Thread and Zigbee multiprotocol SoC.
T-SX1262 wireless transceiver module, using Semtech SX1262 LORA RF transceiver chip design, working in the 868/915MHz ISM frequency band, integrated high st
