2. Hardware
The EV-K0-HCD board measures 3.15 × 3.15 inches or 80 × 80 millimeters (mm). This small form factor
is enabled by the use of components such as inductors that are small in size thanks to the µPD78F8024
MCU’s constant-current drives with high switching frequency.
The board is designed with four layers. The top layer contains most of the components, the first middle
layer serves as the power plane, the second middle layer adds additional space for traces, and the
bottom layer serves as the ground plane and assembly for the temperature sensor and high-power LEDs.
The heat generated by the LEDs is dissipated through the pads and vias surrounding the LEDs, and LED
temperature is sensed by the temperature sensor mounted on top of the dissipation pad.
Figure 1: EV-K0-HCD Board (Top View)
Figure 2: EV-K0-HCD Board (Bottom View)
2.1 Power Supply
The EV-K0-HCD board requires a 10 to 24 VDC power supply with output wattage of at least 5 watts (W)
to light the high-power LEDs. The barrel-type power jack mounted on the board accepts a 2.1 mm center
pole connector (center positive).
2.2 LED Drivers
The board’s four-channel LED drivers are set in buck topology for 350 milliamps (mA) of constant output
current. However, you can increase output current up to 700 mA by changing the current sensor’s
User’s Manual U19610EE3V0UM00

78K0 - Shine It!
resistor values using the following formula (refer to R1, R2, R3 and R4 in the schematics). Please note
that you
need to change the inductors (refer to L1, L2, L3 and L4 in the schematics) current rating accordingly if
you wish to drive at more than 350mA.
LED
SI
R115.0 =
Fomula 1
Where RS= current sensor’s resistor value and ILED = LED current. When driving the LEDs at 350 mA, the
current sensor’s resistor value should be set to 0.33 ohm (Ω).
The number of LEDs that can be used in series per channel is determined by the supply voltage and the
LED forward voltage using this formula:
F
IN
MAX V
V
N≤
Fomula 2
Where VIN = supply voltage, VF= LED forward voltage current, and NMAX = maximum number of LEDs in
series per channel.
Generally, the sum of LED forward voltages must be less than the supply voltage for buck mode
operation. For a 24V power supply, for example, a maximum of six LEDs with 3.5V forward voltage may
be used in series per channel.
LED driver outputs can be connected in one of three configurations:
•To the on-board LUXEON Rebel high-power LEDs
•To LED boards with LUXEON K2 high-power LEDs
•To LED light engines
2.3 On-board LUXEON Rebel LEDs
There are four LUXEON Rebel high-power LEDs mounted on the back of the EV-K0-HCD board, one red
(R), one green (G), one blue (B) and one white (W). By default, the board is set to drive the LEDs with
jumper wires inserted into the four Tyco six-position receptacle connectors (refer to J1, J2, J3 and J4 in
the schematics).

2.4 External LED Board
The EV-K0-HCD board can connect and drive commercially available external LED boards. To do so, you
must first remove the jumper wires inserted into the four Tyco receptacle connectors (J1, J2, J3 and J4)
before installing the LED boards. You can then cascade multiple LED boards in one channel as long as
the number of LEDs meets the requirement specified by Formula 2.
Figure 4: Driving External LED Boards
2.5 LED Light Engine Connector
The EV-K0-HCD board has four LED light engine connectors (refer to J5, J6, J7 and J8 in the
schematics) to the 4-pin terminal block. The following table describes the function of each pin.
Pin Number Function
1 Analog input
2 Ground
3 LED anode
4 LED cathode
Table 1: LED Light Engine Connectors
They can be used to drive up to four off-the-shelf LED light engines, for example, the POWERWHITE™
linear light engine modules from Dialight. Before installing the modules, you must first remove the jumper
wires inserted at the four Tyco receptacle connectors (J1, J2, J3 and J4).
The analog inputs (pin 1 & 2) on the connectors are mainly for connecting to off-board thermister on the
light engine module but can be used for any analog inputs, such as potentiometer, light sensors, etc.
Please not that each analog input is biased with a 10kohm resistor (refer to R11, R12, R13 and R14).
Note: There are six LUXEON Rebel high-power LEDs in series in one POWERWHITE light engine
module. Therefore the power supply must be a 24VDC/1.5A with a 2.1mm center pole
(center positive) Jack connector to meet the requirement specified by Formula 2.

2.6 RS-485/DMX-512 Interface
The EV-K0-HCD board supports DMX-512 protocol over RS-485 using the MCU’s UART0 port. The RS-
485/DMX-512 connector is a 3-pin terminal block connector that accepts up to 24 American Wire Gauge
(AWG) wires.
Pin Number Function
1 Ground
2 D-
3 D+
Table 2: RS-485/DMX-512 Connectors
The µPD78F8024 MCU’s UART0 port is shared between the RS-485 and RS-232 connectors through a
Maxim level shifter (refer to U7 in the schematics). By default, the RS-485 connector is enabled and the
RS-232 one is disabled.
If required, an on-board 110Ωresistor can be inserted between D+ and D- of the RS-485/DMX-512 port
as a terminating resistor. By default, the resistor is disconnected. To connect it, insert a jumper into the
JMP1 header (refer to JMP1 in the schematics).
2.7 RS-232 Interface
A DB9 male connector is used for the RS-232 interface. By default, RS-232 function is disabled. To

2.9 USB Programming and Debugging Interface
The EV-K0-HCD evaluation board implements an on-board USB programming and debugging interface
using the NEC Electronics µPD78F0730 USB MCU. You can download code to the µPD78F8024
HCD/LED MCU from a host computer via a mini-USB cable, and then proceed to debug that code (for
information about debugging refer to the regarding chapter).
2.10 Ambient Light Sensor
The EV-K0-HCD board populates a miniature surface-mount light sensor, part number APDS-9005 from
Avago Technologies, to sense the intensity of ambient light. By default, this sensor is disconnected from
the µPD78F8024 MCU’s A/D converter input. To connect to it, place DIP switch (SW1) position 5 in the
“ON” position.
2.11 Temperature Sensor
The EV-K0-HCD board populates a negative temperature coefficient (NTC) 10 kΩthermistor to sense the
temperature of the on-board LEDs. By default, the thermistor is disconnected from the µPD78F8024
MCU’s A/D converter input. To connect to it, place DIP switch position 6 in the “ON” position.
2.12 DIP Switch
The EV-K0-HCD board uses a 6-position DIP switch (SW1) for configuration purposes. The following
table shows the various configuration options.
