Fitcare Electronics Gives Fitness New Meaning with Smart Watches



Wearables are becoming more and more popular, and Yin Shaoxiang of Fitcare Electronics wanted to put the focus of wearables on professional-level sports and fitness enthusiasts. Fitcare Electronics aims to bring precision and specialization to the wearable market so users can track everything from sleep quality to calorie consumption in order to perform at the top of their game.



Because the founding members all have engineering backgrounds, they were able to tap into their extensive experience working in the development and production of wearables, as well as relationships they’ve developed over the years within the industry. They adopted the EFM32 Wonder Gecko MCU to give them the wide range of sensing technology needed while still providing them with a low-power solution along with the Si1144 HRM optical sensor module for high precision monitoring.

Silicon Labs’ American team and also its local Chinese team gave us fast, professional technical support and helped us reduce power consumption and accelerate the product development process.
