Hi all,

Simple breakout board with all of the supporting components for an off the shelf SIP7 DC/DC module pretty much copy pasted from the module datasheet (LCSC). Board will be assembled with all SMD components on one side and I will solder the through hole parts on the opposite side. I've included a jumper to bypass the inductor in the case that it ends up being an issue or I don't end up needing it. Also included a jumper to select which output of the isolated converter is connected to the safety capacitor to allow for either +15V or -15V output (I think? In addition to swapping which output is connected to the reference on the output).

BOM: 4.7u capacitors (LCSC), inductor (LCSC), 220p Y2 capacitor (LCSC), Generic: 1.5k resistor, green LED, 18V TVS

I'm unsure if the jumper for the safety capacitor is needed, does anyone have any thoughts on it? I just trusted the datasheet recommendation for the inductor value, i made sure the saturation current was well above the max the module input will ever see (550mA) but was wondering if anyone had tips for choosing an input filter like this. I feel like I managed a fairly clean layout but if you notice anything please let me know!

Thanks for your time :^)
