To make it easier for users to quickly evaluate 4G module applications, EXVIST has introduced the 4G LTE USB dongle evaluation kit. This product utilizes the LCC module patch method and incorporates essential power circuitry and a SIM card socket. It communicates via the USB 2.0 protocol and has been designed with practicality and ease of evaluation in mind.The back of the adapter board features a Mirco SIM card socket, while the front houses the 4G module. When users design their own application motherboards, this versatile component can be directly plugged into the motherboard using the USB connection, with fixed holes ensuring stability.
