AK-USBSUPPLY-C
Reference manual for the Artekit AK-USBSUPPLY-C board.
Introduction
The Artekit 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. This board can be used to supply 5V and/or 3.3V to other peripherals and boards by using a standard wall charger, USB hub or a PC USB port.

Features and Characteristics
- Simultaneous 3.3V and 5V power outputs on separated rails.
- 3.3V DC @ max. 800mA.
- 5V DC @ max. 3A.
- Operating temperature: -20ºC/+80ºC
- Compact size.
- Indicator LED.
The CC1 and CC2 pins of the mounted USB-C connector are connected to ground through two 5.1K Ohm resistors. This means that when the AK-USBSUPPLY-C board is connected to a host capable of detecting the board’s power capabilities (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.
Usage
AK-USBSUPPLY-C hardware overview.
The AK-USBSUPPLY-C board is very easy to use. It just requires connecting the board to a host or a wall charger through a USB-C cable. The LED will turn-on when the board is operating correctly and supplying power.
