RAK1500x-MB85RC library is suitable for RAK15003, RAK15004, RAK15005, they use MB85RC256, MB85RC512, MB85RC1M FRAM (Ferroelectric Random Access Memory), using the ferroelectric process and silicon gate CMOS process technologies for forming the nonvolatile memory cells. Unlike SRAM, the MB85RC is able to retain data without using a data backup battery. The read/write endurance of the nonvolatile memory cells used for the MB85RC has improved to be at least 1012 cycles, significantly outperforming other nonvolatile memory products in the number. The MB85RC does not need a polling sequence after writing to the memory such as the case of Flash memory or E2PROM.

In Arduino IDE open Sketch->Include Library->Manage Libraries then search for RAK1500x-MB85RC.
In PlatformIO open PlatformIO Home, switch to libraries and search for RAK1500x-MB85RC. Or install the library project dependencies by adding
lib_deps =
RAKWireless/RAKWireless MB85RC FRAM library
into platformio.ini
For manual installation download the archive, unzip it and place the RAK1500x-MB85RC folder into the library directory. In Arduino IDE this is usually /libraries/ In PlatformIO this is usually <user/.platformio/lib>
The library provides RAK_MB85RC class, which allows communication with MB85RC via IIC. These examples show how to use MB85RC.
