Is there a KiCad symbol and footprint for the TM1640?
Yes. The symbol is EasyEDA_Cloud:MSTM1640(SOP28) and the footprint Package_SO:SOIC-28W_7.5x17.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the TM1640?
SOIC-28-300mil, with 28 pins. Its footprint is drawn on this page.
Where is the TM1640 datasheet?
TM publishes it: the Datasheet link on this page opens it.
Where can I order the TM1640?
JLCPCB lists it as part C41327, with 0 in stock; the sellers' links on this page open their listings.
What can replace the TM1640?
Parts like it in the library: the TM1638 by TM, the TM1640(TA2103) by TM, the TM1628A by TM and the GN1638 by GN Semic. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the TM1640?
12 boards in 10 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
