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.

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
programming
will
erase
