-{{:​m0dule-bus-brd.png?​direct&​200|}}+A m0dul can be connected to the r0ket via the m0dulbus. The connectors are in 2.54mm/​100mil spacing, prepopulated with female sockets. If available, a __stackthrough connector__ should be used to interface with the m0dulbus. The hackerbus is intended for tinkering, a m0dul should use the __m0dulbus only__.

 +==== Dual M0duls ==== 
 +A dual m0dul uses both m0dul connectors on the badge. This gives you maximum mechanical stability and a balanced weight distribution. As the connector on both sides are rotated by 180 degrees you can mount the m0dul 180 degrees rotated.

 +==== Single M0duls ==== 
 +A single m0dul only uses one m0dul connector. These m0duls go to the side of the badge. By rotating the m0dul you can chose to either mount it on the left or the right side of the r0ket.
