+===== BBB =====
+mcmaster goal: come up with a standard connector to put on BBB cape
+Goals:
+  * Requirement: fit 6 connectors on reasonable size BBB cape
+  * Use an existing standard
+  * COTS cables, or at least easily
+  * Shielded
+  * Durable
+Main candidates:
+  * DB9
+    * Durable connector
+    * COTS super available
+    * Shielded
+    * Breakout boards readily available
+    * No insustry standard pinout
+      * I thought Gecko, but that's actually for the motors
+  * DB25
+    * Industry standard connector
+      * Single and multi versions
+    * However, too large
+  * Combicon style connector
+    * Quick to make
+    * Can use shielded cables
+    * Can't buy whole cable, or at least will be expensive
+    * Wires can stress and fall off
+    * Used on Gecko and some others, although not consistently
