The AK-USBSUPPLY-C board takes power from an external power supply through an USB type C cable and delivers 3.3V and 5V through two dedicated pins. You can use this board to supply 5V and 3.3V to other peripherals and boards by using a standard wall charger, USB hub or a PC USB port.
The CC1 and CC2 pins of the USB type C connectors are connected to ground through two 5.1K Ohm resistors. This means that when the AK-USBSUPPLY-C board is used with the right power supply and cable (wall charger or hub with USB-C standard, for example) it can deliver up to 3A on the 5V rail and 800mA on the 3.3V rail (the board mounts an STMicroelectronics LD1117 low-dropout regulator for generating 3.3V, with a maximum output current of 800mA). When used with a USB 2.0 host or power supply, the board can deliver maximum 500mA on both the 3.3V and 5V rails.
There is also an on-board green LED connected to VBUS that signals when the board is receiving 5V from the external power supply.
We also ship this a power supply from USB with a mini conector: the AK-USBSUPPLY board.
