functionality pertaining to this platform shall be designed to comply with the applicable USB and MFi specifications.
C. Indicator Platform: This platform provides the Indicator User Interface (UI) capability. All end-user facing I/O’s, onboard I/O’s, interfaces and
functionality pertaining to this platform shall be designed to comply with the indicator functionality described here within this document.
D. Wireless Charge Module Common Computing Platform (CCP): This platform provides the control logic and communication capabilities. All software
functions, interfaces and libraries should be modular to align with hardware functionality and vice-versa. For example, USB-C Current I/O Platform
Hardware and Software are modular and go together. Standard software development tools and common hardware chipsets shall be used to ensure ease of
development and debugging.
E. Qi Wireless Platform: This platform provides Qi Wireless Charging capability. All end-user facing I/O’s, onboard I/O’s, interfaces and functionality
pertaining to this platform shall be designed to comply with the applicable Qi and MFi specifications.
F. Mechanical Parts and Tooling: The AirPlugs product family shall use common tooling and mechanical parts in order to reduce unique parts count and
tooling.
