Warnings
Warning
Do not use this board in the purpose except the evaluation of MCU.
This board does not take safety measures or anti-EMI measures required for lighting
equipment.
Do not heat the board or expose it to fire, and do not short the terminals.
Doing so may cause product failure, generation of heat, fire, or rupture.
Do not disassemble or modify the board.
Doing so may cause product failure, emission of smoke, fire, or electric shock.
Do not touch with wet hands.
Doing so while power is supplied cause product failure or electrical shock.
Do not drop or jolt the board.
Doing so may break or damage the board, causing fire or electric shock.
Do not turn on power switch in insufficient state of cable connection such as AC
adapter, interface cable.
Doing so may cause product failure, generation of heat, fire or electric shock.
Do not plug in or unplug a connector or cable with power applied to the board.
Doing so may cause product failure, generation of heat, fire or rupture.
Do not carry this board with connecting AC adapter and any cable.
Doing so may cause damage of cable and cause product failure, generation of heat,
fire or electric shock.
Use this board with spacer and on the isolated bench.
In case conductor contact to the board, it may cause product failure, generation of
heat, fire or electric shock.
Use AC adapter adapted to safety standard of each county.
Using non-adopt AC adapter cause product failure, generation of heat, fire or electric
shock.
Use specified power supply.
Using power supply except specified cause product failure, generation of heat, fire or
electric shock.
Use AC adapter with following size and polarity of DC plug.
Using another type of AC adapter may
cause product failure, generation of heat,
fire or electric shock.
Confirm the outlet is near this board and easily unplugged.
If smoke or an abnormal smell or sound is emitted, or heating occurs, promptly
switch off the board power and unplug from AC power supply.
Using the board in such a state poses a risk of fire, burning, or electric shock.

Cautions
Caution
Do not use or store this board in any of the following locations.
- Environments with copious water, humidity, steam, dust, fumes, etc.
- Environments where static electricity or electrical noise is readily generated.
Such influences can lead to electric shock or product failure.
In case liquid enters the board, cut the power supply, and consult your dealer or NEC
Electronics sales representative.
Even if the unit appears to be dry, internal moisture may remain.
To prevent static electricity damage, guard against energizing when touching
metal parts such as the connector.
Static electricity can cause product failure.

Overview
This board is for evaluation of LED dimming control by PWM output from 78K0/IA2
microcontroller.
This board can operate by DC5V power supply provided from AC adapter. Please prepare AC
adapter by yourself. It is also possible to operate by using DC5V provided from “uPD168804
Buck converter HBLED evaluation board (EZ-0007)” in case of using EZ-0007 connecting with this
board. In this case, it is not necessary to use AC adapter.
By using “Lighting Communication Master Evaluation Board (EZ-0008)”, and using GUI tool
which can be download from NEC Electronics’ WEB site, dimming evaluation by DALI or DMX512
communication protocol.
Note. Please short R1 pad which is located near DC plug when using AC adapter.
Please do not short R1 pad when using DC5V power supply from EZ-0007.
