WisBlock RAK12002 RTC Module

This is a WisBlock expansion module from RAK Wireless. The RAK12002 is a real-time clock module with its own battery backup. Once this module is set to the correct date and time, the date and time will continue to be updated even during a power outage. Once the power supply is available again, the WisBlock Core module can receive the correct date and time from the RTC module. 

The WisBlock ecosystem from RAK Wireless offers compact and modular solutions to create your own IoT-LoRaWAN nodes. On a WisBlock Base Board, various CPU, sensor, and IO expansion modules can be mounted. Unlike traditional connectors, the modules are screwed onto the base board. This creates a secure and reliable attachment of industrial quality. Thanks to its modular and compact design, WisBlock is particularly suitable for applications in prototype construction of professional or hobby areas.
