Questions
Is there a KiCad symbol and footprint for the ESP8285?
Yes. The symbol is Espressif:ESP8285 and the footprint EasyEDA_Cloud:QFN-32_L5.0-W5.0-P0.50-BL-EP3.7, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the ESP8285?
QFN-32-EP(5x5), with 33 pins. Its footprint is drawn on this page.
Where is the ESP8285 datasheet?
Espressif Systems publishes it: the Datasheet link on this page opens it.
Where can I order the ESP8285?
JLCPCB lists it as part C83901, with 0 in stock; the sellers' links on this page open their listings.
What can replace the ESP8285?
Parts like it in the library: the RF64 by HopeRF Micro-electronics, the NRF24LE1-F16Q32-R by Nordic Semicon, the ESP8089 by Espressif Systems and the CYW20736A1KML2G by Infineon Technologies. Check their datasheets: a part that fits the footprint may still differ in its ratings.
