Also schematic for Fire Core is not available. No info about PSRAM pinout with a potentially problematic with BUS C connector (GPIO16,17 used for Groove UART, seems also used for PSRAM, so it's a conflict?)
Please publish the schematic for M5Stack Fire Core. Please again.
The GPIO 16 / 17 in Fire is connected to the PSRAM by default, so when you connect or stack other function modules, you need to avoid conflicts with these two pins to prevent the device from working properly and causing instability.
This is not an answer. Please tell me
If I use FIRE CORE PSRAM, GROVE PORT C on m5go base is unusable
Yes or no ?
YES, You can only use one of them(PSRAM or PORT C)
There are a number of schematic issues:
