      I am using OneWire on Pin19 as digital inputs 1,2,3,5,16,17 used. Now I see conflict when initializing SD card. Is File management / SD card management also using Pin 19? Other pin I could use beyond those occupied already?

        Hello @fly4fun

        yes, on M5Stack (Basic, Gray, Fire) GPIO19 is MISO (which is part of SPI) and is used for the SD card as SPI_SDDO. You can see that from the pin map or on the schematic here.

        Thanks
