ESP32-S3 I2C Pullup Resistors : are they necessary ?
Hello,
I have been working with ESP32-S3 for several years (T-Display Lilygo and XIAO boards) in the Arduino environment, and I have just realised that the I2C bus (which I have implemented on several different circuits: TC74, SHT21, PCF85263, DS3231, etc.) taking care to add pull-up resistors, as ...
