Adjustable breadboard power supply - 2 outputs ?

by tfcroft4 on Tue Aug 24, 2010 4:09 pm

Could the Adjustable breadboard power supply be adjusted to give a Vcc for MCU 5 or 3.3v plus a higher voltage for a set of large 7 seg LEDs hence giving a power supply for a clock with 6 2.5" or 4" 7 segment LEds which might need 7 - 9v

The breadboard power supply output is selectable between 3.3, 5 and adjustable voltage. But if you power it with the Adafruit 9v regulated adapter, you can tap off the regulated 9v for other uses too.

So two outputs would be feasible. Say 9v in then 5v and 7v out. Just checking. Thanks.

No. The adjustable supply only has one output. What I am saying is that if you need 5v for the clock and 9v for the seven-segment display, you can feed the breadboard supply with 9v and set it to output 5v for the clock. You can also use that 9v for your 7-segment display.

a clock with 6 2.5" or 4" 7 segment LEds which might need 7 - 9v
