whitebox-labs/tentacle
An arduino shield to host and individually isolate up to 4 Atlas Scientific sensor circuits. Measure pH, conductivity, dissolved oxygen, ORP, temperature

The R1SE-0505-R is an isolated Power Module made by RECOM Power in a SMD-5P package with 5 pins.
PCBKit's library has its footprint (EasyEDA_Cloud:PWMR-SMD_R1SE-0505-R, from EasyEDA), ready for a KiCad board. JLCPCB lists it (part C94818). 3 open-source boards in 3 repositories on GitHub use it.
The library has no symbol for this part yet.
