is it have 5v to 12v dc output?

[@KinCony]

do you want to adjust voltage output?

[@yeongmuseo7737]

@@KinCony yes i want connect rs485 power for 5v to 12v

[@KinCony]

@@yeongmuseo7737 sorry, i don't understand you. why RS485 need 5--12v?

[@yeongmuseo7737]

@@KinCony The sensor module I want receives a separate 5v~12v variable voltage as input power.

[@yeongmuseo7737]

@@KinCony This can be developed in the direction of mounting a power board separately.
However, the interest is whether the board developed by Kinconi is compatible.
