I need to power the module with 24V, to do that I’ve desoldered the power barrel connector and soldered a 24V to 5V SIP3 DC-DC switching converter on the solder side of the board, see the attached image.
Of course this can be enough for some lab testing but not for production, not a clean solution.
I’ve see that the IL1117C-3.3 low dropout voltage regulator is supplied directly through the input connector and I’ve to be sure that the 5V is not anymore used inside the board. If this is right I can desolder the U5 linear regulator and use in place of it a SIP3 DC-DC 24V to 3.3V switching regulator in order to power directly the module with a 24V DC power supply.
I kindly request if is possible to have a electrical schematic of the WIZ110SR REV1.0 board or simply a confirm that the 5V voltage is only used to power the U5 linear regulator and not used anymore into the board to avoid any board damage.
Looking forward to hearing from you!
