Application scenarios: , 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 positioning, support AGNSS function, built-in low noise amplifier and 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 time for the first positioning, built-in low-noise amplifier, can achieve high sensitivity, high-precision positioning and fast signal capture and , even under weak signal conditions can also a good positioning performance, built-in 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- Introduce: At the beginning of the design, more consideration was to adapt to Meshtastic and SoftRF, so Bluetooth and low power consumption were considered when designing, and NRF52840 Advanced Bluetooth 5 was Thread and Zigbee multiprotocol SoC. T-SX1262 wireless ceiver module, using SX1262 LORA ceiver chip design, working in the 868/915MHz ISM frequency band, integrated high ability TCXO 32MHz crystal oscillator, half-duplex ceiver module, power up to +22dBm, receiving sensitivity -139dBm. Automatic ceiver Switching, internal mission and reception channel isolation, advanced LORA spread spect communication technology, strong anti-interference and privacy, can realize long-distance wireless data mission and reception.
