915Mhz LoRa Expansion Board for Raspberry Pi Pico
Pico LoRa Expansion is a low-power consumption data transmission board that comes with an onboard CH340 USB TO UART converter, Voltage Level Translator (74HC125V), E22-900T22S SMA antenna connector that covers 433MHz frequency band, Onboard 1.14″ LCD, IPEX antenna connector, LoRa Spread Spectrum Modulation technology with multi-level auto repeating. Pico LoRa Expansion is developed to enable data transmission up to 5 KM through the serial port.
LoRa spread spectrum modulation technology with the new generation, and users can easily transmit data with low power consumption. E22-900T22S Pico LoRa Expansion discrete itself from the normal LoRa with its longer communication distance, lower power consumption, better safety, and ani-inference system. USB-UART communication of Pico LoRa enables direct communication with a desktop/laptop without using Raspberry Pi Pico.
LoRa is the abbreviation of Long-range that runs on a spread-spectrum technique procured from chirp spread spectrum (CSS) technology. It encodes information using the wideband linear frequency modulated chirp pulses.
