Hello. A friend gave me a couple of esp32-c3 processors with crystals on them that he bodge up together that the pcb looks like the ones from amazon. Now the only problem I see Is on all esp32 and esp that there are spi windond flash memory on them, But this one doesn't have any. Is that needed? Also I couldn't find A arduino pinout of this processor. Does anyone know the arduino pinout for this processor?
Edit" I'm trying to see if I can program this processor But I can not find arduino pinout. I did do a search I did find a lot but not the pinout. Only the GPIO pinout.
