[Design Development Outsourcing / ODM Case] Communication Board for Smart Keys

A case that achieved miniaturization of the substrate size and responded to requests for power saving.

We would like to introduce a case where we received a request from a housing equipment manufacturer to develop a circuit board for a smart key to be used in a key system. The cover for the smart key was designed by the customer, and it was necessary to develop a circuit board that could achieve miniaturization while considering the required specifications. Additionally, the smart key required operation on a button battery, and it was essential to design for low power consumption to ensure that the battery replacement frequency would be over one year. For power saving, we utilized the microcontroller's sleep mode. Furthermore, to achieve miniaturization, we used a small-scale microcontroller and developed it without an operating system. **Our Proposals and Services:** - Equipped with a vibration sensor, it only activates when a certain level of vibration is detected. - Acting as an agent for obtaining permission for specific low-power radio stations. - Thorough noise countermeasures implemented during the circuit design and pattern design stages. - We provide consistent support from prototype development to mass production, responding to requests to consolidate outsourcing partners and reduce management workload. *For more details, please refer to the related links or feel free to contact us.*
