USB ports interface[edit | edit source]
Description[edit | edit source]
The AXEL ULite Evaluation Kit provides two USB ports, one Host and one Host/OTG optional ports:
- J11 is a standard USB Host 2.0 Type A connector
- J22 is a micro-AB type receptacle for an optional USB Host/OTG connection: this interface can be mounted on request and provide an Host or an OTG USB additional port:
Signals[edit | edit source]
The following table describes the interface signals
