Not all I2C devices (especially Magnetic sensors) need the pull-up resistors, or better said, in general, most of them don’t need them, especially with Arduino UNO. The picture above shows how solder the pads in order to enable the Pull-up resistors. Enabling I2C pull-up resistorsįrom the shield version 1.3.2 the boards come with with 4.7KOhm pull-up resistors for I2C communication pins. For those of us who are looking for price optimization :slight_smile:, a lot of cheap Ebay/Aliexpress encoders will need them such as 600P ebay encoder and similar. Not all encoders need the pull-up resistors, or better said, in general, most of them don’t need them. Enabling encoder/hall sensor pull-up resistorsĮach board has integrated set of three 3.3KOhm pull-up resistors for encoder channels A,B and Index (or Hall sensor U, V, W). Therefore once you have the board, if you wish to change configuration all you need to do is remove the ink with some wet paper wipe. The testing configuration will be done with use of conductive ink instead of soldering connections.
