![]() He explains that over time the timing of resonators might become offset and might pose difficulty when communicating between chips. I have seen the HC-49S come across more often in other projects so I decided to just go with this one.Īs for the decision to go for a crystal over a resonator I reference this video by Derek Molloy. He very kindly specified the source from where he bought the crystal in the description of the video in which we find that he used a HC-49S, 16MHz, 20pF load capacitance, frequency tolerance of +/- 20ppm. I found one source that clearly references the specs of the crystal with proof it works. ![]() ![]() In the end I see a lot of sources just say 16MHz and two 22pF. Many sources on the internet just specify a 16MHz crystal without specifying the load capacitance of the crystal they use. It has been a frustrating process to find a straight answer. ![]() I have been reading many forum posts on different forums that ask about the same question I asked here. ![]()
