I2C Pull-up

Overview

The component I2C Pull-up provides two 1k resistors for the usage as pull-up for the I2C bus. The resistors are independent.

Example

An example project for the Arduino IDE can be downloaded: I2C-Scanner.ino (download here).

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

SDA	SCL
SW307	SW308
IO19	IO4

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.
