redboard vs redboard plus voltage problem.

Development Boards Arduino
1

Installed a Redboard “arduino” for my skeeball score controller. The board worked for a few years then it lost an output channel. Not wanting to change the program to allow another output to work, I decided to go with a new unit. Unfortunately they are no longer available. I went with the Redboard Plus rewired the same outputs and qwiic. downloaded the same program but only get 3.5 volts which is not enough to power LCD display or LED reset button

I selected 5v on the 3.5 - 5v switch to no avail. how can I get 5 volts to my devices.

Thanks for any reply,

Dave

The Qwiic bus only supplies 3.3v, so either:

disconnect the Positive lead on that and power your device viz the 5v pin from the redboard (labeled under the “power” section of the redboard), or

re-wire to use the pins (5v, SDA, SCL, GND) instead of qwiic

Tried to edit original post. Initial board was a Redboard Edge.

Thanks TS,

I"ll try to send 5 volts to SDA,SCL, GND pins for the display rather than using qwiic plug.

How do I get 5 volts to pin 13 for my 5 volt required LED??
