RENESAS Smart Lock Reference Design

This is the reference design of RENESAS Smart Lock, which is one of the example solutions using RL78 / G1D. It is provided in a format that allows you to use it with our free DesignSpark PCB software to edit it freely. To download the RENESAS Smart Lock project files, please refer to the end of this article.

 

RENESAS Smart Lock is a board that allows key unlocking/locking using Bluetooth. Using Bluetooth® Low Energy (BLE) on the board, RL78 / G1D can be used to remotely lock and unlock keys and confirm the status with low current and low power consumption. As an example, it is possible to improve safety by locking/unlocking keys and checking the status of the application via a smartphone. There is also an alarm notification function when the key is disconnected in a locked state, or the password change function is used.

Key features

  • Remote key locking/unlocking, confirmation of status
  • Low current consumption and low power consumption
  • Key control with smartphone
  • Alarm function and password change function when key is disconnected
