Questions
Is there a KiCad symbol and footprint for the MAX490ESA+?
Yes. The symbol is Interface_UART:MAX490E and the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the MAX490ESA+?
SO-8, with 8 pins. Its footprint is drawn on this page.
Where is the MAX490ESA+ datasheet?
Maxim Integrated (Analog Devices) publishes it: the Datasheet link on this page opens it.
Where can I order the MAX490ESA+?
JLCPCB lists it as part C2762957, with 19 in stock; the sellers' links on this page open their listings.
What can replace the MAX490ESA+?
Parts like it in the library: the SP3485EN-L/TR by MaxLinear, the SP485EEN-L/TR by MaxLinear, the SN75176BD by Texas Instruments and the MAX485ESA+T by Maxim Integrated (Analog Devices). Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the MAX490ESA+?
4 boards in 3 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
