Back at Ladyada's Desk! Doing bringup on PORT AUTHORITY our 'smart' controllable USB HUB
We got tired of using crummy USB hubs. Do they have individual port control? Maybe...maybe not! Do they have voltage and current monitoring? Never! What about XH or USB A for fixed connections that don't flop out? I2C control or EEPROM for configuration? Proper protected input ports with 5V overcurrent/overvoltage protection? ESD and overcurrent protection on each port? YES YES YES, it's time for PORT AUTHORITY, the stackable USB hub we always wanted! Starring the USB2514 hub, TPS259470A eFuse, and TPS2117 power mux to select between USB self- or external power. Visit the Adafruit shop online…
