4.4 USB Host Connectors (P11, P15)
The four USB2.0 host ports provided by the CM-A510 are available through two dual type-A USB
connectors (P11 & P15).
For USB ports 1, 2 and 3, the CM-A510 provides the “VBUS enable” signal and monitors the
“VBUS good” signal generated on SB-A510. USB port 0 power is controlled by GPIO00, and
monitored by GPIO01, on the I2C GPIO extender onboard the SB-A510.
NOTE: The actual number of USB2.0 ports available depends on the CM-A510 USB
configuration option.
