The YRPBRL78G14 is a promotion board for the new Renesas RL78 microcontroller family. It supports on-board debugging, flash programming, and is pre-programmed to work with the GUI provided on the included DVD to demonstrate the low-power capabilities of the Renesas RL78 MCU.

The box had turned slightly yellow due to age and light, but the boards are still fully operational and non opened.
