[High performance and ultra-low power consumption] Transmitting power up to 22dBm; supports 1.76~62.5kbps transmission rate, -129dBm sensitivity; only 1.62uA in sleep mode;
[Ultra-small size] The size is only 10*10*3.5mm, 20-pin patch stamp hole design, easy to integrate into the motherboard;
[Wireless communication] Supports 850~930MHz global LoRa&LoRaWAN ISM frequency;
[FCC, CE certification]
LRCC68 is a LoRa wireless communication module based on Semtech LLCC68 chip, designed for 868MHz and 915MHz frequency bands. It adopts ultra-small package and patch-type stamp hole design for easy motherboard integration. The module adopts advanced LoRa modulation technology, which has stronger anti-interference performance and longer communication distance than traditional FSK and GFSK.
Its maximum transmission power can reach +22dBm, supports 1.76~62.5kbps transmission rate, and covers 850~930MHz global LoRa&LoRaWAN ISM frequency. It is equipped with high-quality TCXO crystal oscillator, high and low temperature resistance, stable operation, and sleep current as low as 1.62uA, which is particularly suitable for smart home, wireless meter reading, scientific research and medical and medium and long-distance wireless communication equipment.
(Note: The module needs to be paired with an MCU driver or a dedicated SPI debugging tool to work properly)
Application scenarios
Smart city, smart agriculture, industrial automation, environmental monitoring, smart home, logistics management, medical health.
