# STM32F7_Discovery_Boards Digital Pin

Do any of the pins on CN9 or CN13 on the STM32F7 Discovery Board have a constant 3.3 or 5V output?

• When you say "digital pins" do you mean the GPIO, or any available pin? – Ron Beyer Jun 27 '19 at 21:25
• Sorry the Arduino connectors on the right side CN9 or CN13 ? – Dwayne Jun 27 '19 at 21:49
• i think that you should be asking if there are any power pins on the board .... digital pins usually refers to data pins – jsotola Jun 28 '19 at 2:04
• Identify which STM32F7 discovery board. The answer depends on how you power your board. USB is meant to power these boards, but if you provide external power, you have 5V at USB connector. It is how USB works. – StainlessSteelRat Jul 1 '19 at 20:09
• So my question should have been does this board have constant voltage at the Arduino pins are they constantly on like on a TI board. - anyway – Dwayne Jul 3 '19 at 13:45
