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), E22-400T22S & E22-900T22S SMA antenna connector that covers 433, 868 & 915 MHz 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.
With the new generation of LoRa™ spread spectrum modulation technology, users can easily transmit data with low power consumption. E22-400T22S & E22-900T22S Pico LoRa™ Expansion discrete itself from the normal LoRa™ with its longer communication distance, lower power consumption with 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.
