It looks like a resonator is allready soldered to the board, for this produc, with external capasitors: https://lechacalshop.com/misc/23-atmega328-tqfp32-arduino-socket-programmer.html What is the frequency of the resonator, and what is the package size (or better: manufacturer part number) of the resonator. If not 8Mhz, then I need to replace it.
The resonator is 16Mhz. On newest versions the package is 11.4 mm x 4.7 mm SMD.
