Questions
Is there a KiCad symbol and footprint for the ESP-M2?
Yes. The symbol is EasyEDA_Cloud:ESP-M1_C19949056 and the footprint EasyEDA_Cloud:WIRELM-SMD_ESP-M2_C19949057, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the ESP-M2?
SMD,20x12.3mm, with 16 pins. Its footprint is drawn on this page.
Where is the ESP-M2 datasheet?
DOIT publishes it: the Datasheet link on this page opens it.
Where can I order the ESP-M2?
JLCPCB lists it as part C19949057, with 375 in stock; the sellers' links on this page open their listings.
What can replace the ESP-M2?
Parts like it in the library: the ESP32-WROOM-32E-N4 by Espressif Systems, the ESP-12F(ESP8266MOD) by Ai-Thinker, the ESP32-WROOM-32 by Espressif Systems and the ESP32-WROOM-32E-N16 by Espressif Systems. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the ESP-M2?
3 boards in 3 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
