Before You Begin
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
can result in bent pins inside the port or
possible overheating of the expansion
board when connected.

Connecting Cable
Connectors To Strip Lights
Take extra care when inserting connectors
to ports on the Strip Lights. Connectors
can be inserted only one way. With the
Strip Light facing up, ensure the side of
the connector with the wires exposed is
facing down. If a plug won’t fit easily into
a port connector, don’t force it. Doing so
will damage the plug and the connector.
Connecting Micro Cable
Connectors To Micro
Expansion Board Ports
Take extra care when inserting the
micro connectors to micro ports of Micro
Expansion Boards. Connecting Micro Bit
Lights to Micro Expansion Boards is similar
to connecting lights and cables to Strip
Lights. With the expansion board facing
up, ensure the side of the connector with
the wires exposed is facing down. If a plug
won’t fit easily into a port connector, do
not force it. Use your fingernail to push the
plastic part of the connector to the micro
port.

Installing Bit Lights Under
Lego® Bricks And Plates
When installing Bit Lights under LEGO®
pieces, ensure they are placed the correct
way up (Yellow LED component exposed).
You can either place them directly on top of
LEGO® studs or in between.
