SPI
SPI Data Rate: The SPI port is shared with the microSD card. The Arduino Board for the ESP32 doesn't allow
multiple data rates, so when using the SPI port for your own peripherals, the SD data rate will be constrained to
the lowest common speed capability.
Now wire the BME280 up to the ESP32’s SPI port.
Connect the BME280 SPI port
Here are the connections in the picture.
