Overview
The CI1102 is a microcontroller Unit made by Chiplntelli in a SMD package with 57 pins. 160MHz 3.6V~5.5V ARM Cortex-M4 SMD Microcontrollers (MCU/MPU/SOC) ROHS.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:CI1103, from EasyEDA) and its footprint (EasyEDA_Cloud:QFN-56_L7.0-W7.0-P0.40-BL-EP5.1, from EasyEDA), ready for a KiCad board. JLCPCB lists it (part C485995).

Is there a KiCad symbol and footprint for the CI1102?
Yes. The symbol is EasyEDA_Cloud:CI1103 and the footprint EasyEDA_Cloud:QFN-56_L7.0-W7.0-P0.40-BL-EP5.1, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the CI1102?
SMD, with 57 pins. Its footprint is drawn on this page.
Where is the CI1102 datasheet?
Chiplntelli publishes it: the Datasheet link on this page opens it.
Where can I order the CI1102?
JLCPCB lists it as part C485995, with 0 in stock; the sellers' links on this page open their listings.
What can replace the CI1102?
Parts like it in the library: the CI1103 by Chiplntelli. Check their datasheets: a part that fits the footprint may still differ in its ratings.
