May I know reference values of RTC crystal X2 and Capacitors C17/C18? It is marked in attached photo. Thank you very much

This crystal is the 32.768KHz crystal connected to the STM32 RTC. It was quite expensive to find in such small package and we did not have any use for it but we still put the pads for it and its capacitor if anyone is finding use for the RTC (ie. the Crazyflie only has a ceramic resonator at +/- 1% if I remember well, if you need better time-keeping capability the 32KHz crystal is a way to have it).
