BRIX₂ Extension Modules

BRIX₂ Extension Modules can be used to extend the capabilities of the BRIX₂ Base Module and are an important feature of the BRIX₂ system. Most Extension Modules are small PCBs that fit into a single Lego brick and can be connected to one of the three Extension Ports of the BRIX₂ Base Module.

Pin Usage Overview

Some BRIX₂ Extension Modules use the same pins on the Extension Connector for different purposes. If those Extensions are used on the same Base Module at the same time, they may interfere with each other, causing errors in your application. Make sure that your Extensions do not conflict. In some cases, two Extensions using the same pins will work, especially on the SDA and SCL pins, which are designed as a bus which can serve more than one device.
