I2C connector - speedmeup - 09-05-2024
Hi,
What is the name of the white I2C connector used on the board if I want to purchase them to make up cables?
Can I use any I2C bus address I choose or is the white connector bus shared with the pcf8574 expanders so I must avoid 0x23, 0x24,0x25 and 0x26?
Thanks!

Could you post the YAML (EspHome) config for using the I2C port for connect a i2c temperature sensor?

suggest use SHT30 i2c temperature sensor, here is yaml: https://esphome.io/components/sensor/sht3xd.html
