10. Compatible with the DT-COMBO BASE BOARD Series.

Layout

ISP HEADER (J8) is a connector for ISP programming.

HWB (S1) tactile switch is used during programming via

bootloader.

HEADER 1 (J2), HEADER 2 (J3), HEADER 3 (J4), and

HEADER 4 (J5) connectors are power supply and

input/output lines that can be connected to SOCKET 1 -

SOCKET 4 on the DT-COMBO BASE BOARD Series. Use

the triangle marks on both modules as reference. Both

marks should be in the same position and direction. Also

pay attention to the position of the CPU MODULE

connectors so that the installation is precisely aligned

between pins (not shifted).

Important!

• VCC can be drawn from external power source

(VEXT) or from USB (VBUS).

• AVCC is connected by an inductor to the currently

used power supply line (VEXT form external

power supply or VBUS from USB).

• PGND and AGND are connected by lines on the

PCB.

• PD.7 is also connected to the HWB (S1) tactile

switch used during bootloader operation.

• Pay attention to the pin order at the DT-AVR

AT90USB162 CPU MODULE when connecting it

with another module.

Jumper J7 is used to select function and line of PC.0.

To enter bootloader mode, connect mini USB to computer.

Press and hold HWB (S1) tactile switch, and then press

Reset tactile switch on the DT-COMBO BASIC BASE

BOARD. Release Reset tactile switch and then release

HWB tactile switch. Afterward, DT-AVR AT90USB162

CPU MODULE can be connected to the PC using a serial

cable. Choose a suitable port on FLIP as a programming

line.

Important!

• Programming via bootloader does not need

additional programming device.

• Programming can only be performed via one of

the features, via bootloader or via ISP (with

additional ISP programmer).

• ISP header programming will erase the

bootloader program inside the IC.

Jumper J6, J9, J10, J11, and J12 is used to choose the

power source that will be used.

Testing Procedure

1. This test uses the DT-COMBO BASIC BASE BOARD.

Connect DT-AVR AT90USB162 CPU MODULE to it.

2. On the DT-COMBO BASIC BASE BOARD perform

these following steps::

• Release jumper J31 and arrange jumper J34 and

J35 to point 2-3.

• Arrange jumper J22, J23, J24, J25, J26, J27,

J28, and J29 to point 2-3.

• Connect PORT B, PORT C, and PORT D with DT-

I/O LED LOGIC TESTER or a series of active low

LEDs.

• Connect J2 (UART1) DT-COMBO BASIC BASE

BOARD connector with the computer serial port

using a serial cable.

3. Arrange jumper J7 on the DT-AVR AT90USB162 CPU

MODULE on position 2-3.

4. Arrange jumper J6, J9, J10, J11, and J12 for Self

Power 5V, then connect the DT-AVR AT90USB162

CPU MODULE to PC using a USB cable.

5. Connect a 6.5-12 Volts DC power supply to the DT-

COMBO BASIC BASE BOARD DC port. The power

LEDs on the DT-AVR AT90USB162 CPU MODULE and

J10 J6 J9

J11 J12J11 J12

J11 J12

DT-COMBO BASIC BASE BOARD will light up. If one

or both LEDs do not light up recheck the connections

between the modules and the power supply.

6. Program the AT90USB162 TEST FILE.HEX using

bootloader mode and FLIP.

7. If the download process succeeded, the LEDs

connected to Port B, Port C,and Port D will light up

alternately representing the binary numbers of 0-

255. The LEDs at Port D bit 2 and 3 will not light up

because they are used as UART serial communication

lines. While the LEDs on Port C bit 0,1, and 3 will not

light up.

8. Run the terminal program on the computer to see the

serial data sent by the module to the computer. This

serial communication uses the following configuration:

• Baud rate : 9600 bps

• Data bit : 8

• Parity : none

• Stop bit : 1

• Flow control : none

9. When using a HEX view (not ASCII), monitor screen

will show hex numbers from 00H up to FFH sent

repeatedly.
