Power Supply

Edge 2 takes power in one of three ways: USB-C Power Delivery, a 12 V DC adapter, or 12 V through the SATA power connector. Use one input at a time.

Requirements

Input	Where	Requirement
USB Power Delivery	POWER, the USB-C port at the corner of the board	A USB PD 2.0 or PD 3.0 adapter, connected with a USB-C to USB-C cable such as the one in the box. The board accepts 5 V to 20 V, up to 20 V at 3 A.
12 V DC	DC 12V, the round jack on the short edge	A 12 V adapter that supplies at least 2 A. The board draws up to 3 A.
12 V through SATA power	The SATA power connector next to the DC jack, pins 13 to 15	12 V at up to 3 A, for example from the power supply of an enclosure

For USB-C power, the adapter must support USB PD and the cable must be USB-C to USB-C. A USB-A to USB-C cable does not negotiate PD.

The POWER port also carries USB 2.0 data. While the board is powered from the DC jack, the same port connects Edge 2 to a computer for flashing.

Powering attached devices

The board's connectors supply power to what you attach to them, each within its own limit:

Output	Where	Limit
5 V	Each USB 3.0 Type-A port	1 A
5 V	5V output connector	2 A in total
5 V	CAN connector, pin 1	200 mA
3.3 V	UART3 and UART5 connectors, pin 1	100 mA each
3.3 V	I²C connector, pin 1	100 mA
3.8 V	M.2 and Mini PCIe sockets	3 A in total

Devices that draw more than this need their own supply.
