1 Power Supplies
The Basys 3 board can receive power from the Digilent USB-JTAG port (J4) or from a 5V external power supply.
Jumper JP3 (near the power switch) determines which source is used.
All Basys 3 power supplies can be turned on and off by a single logic-level power switch (SW16). A power-good LED
(LD20), driven by the "power good" output of the LTC3633 supply, indicates that the supplies are turned on and
operating normally. An overview of the Basys 3 power circuit is shown in Fig. 2.
