Laying cables in between 
and underneath bricks
Cables can fit in between and underneath 
LEGO
®
 bricks, plates, and tiles providing 
they are laid correctly between the LEGO
®
 
studs. Do NOT forcefully join LEGO
®
 
together around cables; instead ensure 
they are laying comfortably in between 
each stud.
CAUTION: Forcing LEGO
®
 to connect over 
a cable can result in damaging the cable 
and light.
Connecting Cable 
Connectors To Expansion 
Boards
Take extra care when inserting connectors 
to ports of Expansion Boards. Connectors 
can be inserted only one way. With the 
expansion board facing up, look for the 
soldered “=” symbol on the left side of the 
port. The connector side with the wires 
exposed should be facing toward the 
soldered “=” symbol as you insert into the 
port. If a plug won’t fit easily into a port 
connector, do not force it.
Incorrectly inserting the connector can re-
sult in bent pins inside the port or possible 
overheating of the expansion board when 
connected.
