Diagrams
Block diagrams do not necessarily show the exact wiring in hardware but the
functional structure. Timing diagrams are for functional explanation purposes only,
without any relevance to the real hardware implementation.
Safety Precautions
This document describes items to be observed to ensure the safe use of this evaluation board. Be sure to
read this document before using the board.
Symbols Used
This document uses the following symbols for items to be observed to ensure the safe use of the unit.
The symbols are followed by a brief explanation of the possible extent of problems which may occur if the
items are not observed.
The risk is high if the warning is not
observed, and the user may suffer death
or serious injury.
The user may suffer death or serious
injury if the warning is not observed.
Human injury or property damage may
occur if the caution is not observed.
Danger
Warning
Caution
The following symbols express behaviors that are prohibited in order to prevent injury or accident.
General prohibition
The action mentioned
is prohibited.
Do not touch
Touching the specified
location may cause
injury.
Flammable
Proximity to flame
may cause the unit to
catch fire.
Do not disassemble
Disassembly may
cause a problem such
as electric shock or
product failure.

The following symbols are used for instructions to prevent product failure and accidents.
Instruction to unplug from AC power
supply
Action required of the user
Warnings
Warning
Be careful to avoid burns.
The temperature of this part of board increases when AC power is connected.
Be careful of LED brightness and the LED On/Off interval.
Simulations of strong light may cause symptoms linked to an epileptic condition.
Do not use this board for a purpose other than the evaluation of an MCU.
This board does not include the 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 the product to fail, heat up, catch fire, or rupture.
Do not disassemble or modify the board.
Doing so may cause the product to fail, emit smoke, or catch fire, or result in electric shock.
Do not touch with wet hands.
Doing so while connected to power may cause the product to fail or result in electric shock.
Do not look directly at the LEDs on this board.
Doing so may weaken eyesight.
Do not drop the board or subject the board to heavy impact.
Doing so may break or damage the board, causing fire or electric shock.
Do not turn on the power switch when the AC adapter, interface cable, or other cables are
not properly connected.
Doing so may cause the product to fail, heat up, or catch fire, or result in electric shock.
Do not plug in or unplug a connector or cable with power applied to the board.
Doing so may cause the product to fail, heat up, or catch fire, or result in electric shock.
Do not move this board when the AC adapter or any cables are connected.
Doing so may damage cables and cause the product to fail, heat up, or catch fire, or result in
electric shock.
Use this board with a spacer and on an electrically isolated bench.
If a conductor contacts the board, the product may fail, heat up, or catch fire, or it may result in
electric shock.
Use an AC adapter adapted to the safety standard of each country.
Using an inappropriate AC adapter may cause the product to fail, heat up, or catch fire, or result
in electric shock.
Use the specified AC adapter.
Using an AC adapter other than that specified may cause the product to fail, heat up, or catch
fire, or result in electric shock.
Use an AC adapter of the following size and DC plug polarity.
EIAJ Type2 Plug (outer diameter: 4.0 mm, inner diameter: 1.7 mm)
Using another type of AC adapter may cause the product to fail, heat up, or catch fire, or result in
electric shock.
Confirm that the outlet is near this board and can be easily unplugged.
Warning
If smoke or an abnormal smell or sound is emitted or if overheating occurs, promptly
switch off the board power and unplug the 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 excessive water, humidity, steam, dust, fume, etc.
- Environments where static electricity or electrical noise is readily generated.
Such influences can lead to electric shock or product failure.
If liquid enters the board, disconnect the power supply, and consult your dealer or Renesas
Electronics sales representative.
Even if the unit appears to be dry, internal moisture may remain.
Do not directly touch LEDs on this board.
Doing so may cause product failure.
To prevent static electricity damage, guard against static discharge when touching metal
parts such as the connector.
Static electricity can cause product failure.
