|ESP Board||I2C pull-up|
|SW307 and SW308|
Activating the component¶
The left resistor can be connected to SDA with SW307 and the right resistor to SCL with SW308. The resistor on SW307 is connected to io port 19 and the resistor on SW308 is connected to io port 4
Using the component¶
There is no special source code needed for this component. If you need an pull-up in your project you have to activate the appropriate pull-up.
