[Design Development Outsourcing/ODM Case] Receiver Board for Key Systems

An example of achieving acceleration by utilizing original multitasking control without using an OS.

We would like to introduce a case where we received a development request for a receiving board that controls operations through wireless communication with a smart key from a housing equipment manufacturer. In this key system, in addition to integration with the smart key, locking and unlocking can be performed from a smartphone. The board is embedded within a metal door, raising concerns about potential communication issues, necessitating countermeasures. Regarding integration with smartphones, we developed the board in a way that is compatible with the selected communication interface, BLE. Additionally, we installed a prototype in a real environment and improved the antenna, successfully developing a reader board that can receive signals without issues. [Our Proposals and Services] - Use of a small microcontroller for software control without an operating system - Achieving high speed by utilizing our own multitasking control without an operating system - Thorough noise countermeasures from the circuit design stage, including separating power supplies for different types of signals (three types), enabling stable operation *For more details, please refer to the related links or feel free to contact us.
