K4 (dual-band Wi-Fi) is a series of LOOFII’s new generation of multi-mode Smart LTE Cat 4 module with built-in Android 10 OS. Based on Unisoc quad-core ARM Cortex-A53 64-bit high-performance processor with built-in ARM Mali-T820 GPU, it is an ideal solution for both industrial and consumer applications requiring high data rates and multimedia functions. K4 series (dual-band Wi-Fi) is available in four variants: K4A01, K4A02, K4A03 and K4A04.
K4 series (dual-band Wi-Fi) supports multiple-input multiple-output (MIMO) technology. The use of multiple antennas at the receiver end at the same time and on the same frequency band greatly minimizes errors and optimizes the data speed. This module also combines high-speed wireless connectivity with embedded multi-constellation and high-sensitivity GNSS (GPS, GLONASS and BDS) receiver for positioning.
A rich set of interfaces (such as LCM, Camera, Touch Panel, MIC, SPK, UART, USB, I2C, SPI) extend the applicability of the module to a wide range of M2M applications, including smart POS, smart cash registers, smart home gateways, smart robots, smart wearables, security surveillance, PDA & tablets, vending machines, delivery lockers, police and law enforcement equipment, in-car video streaming and entertainment systems, etc.
