DT-AVR
ATMEGA328 CPU Module
DT-AVR ATMEGA328 CPU Module
is an
AVR
®
ATmega328(P) based microcontroller module. It
features an In-System Programming (ISP). This module can
be connect to the DT-COMBO BASE BOARD Series and
used for various applications.
Specif
ications
1. ATmega328(P) based (32 KB Flash Memory, 1 KB
EEPROM, & 2 KB Internal SRAM).
2. Up to 22 Input/Output pins, including 2 8bits
timers/counters, 1 16bits timer/counter, 6 PWM
canals, 8 10bits ADC canals, serial USART, watchdog
timer, and analog comparator.
3. 8 MHz crystal oscillator.
4. A port for ISP programming
5. Programming LED indicator.
6. 2.7 – 5.5 Volts DC power supply (VCC).
7. Compatible with the DT-COMBO BASE BOARD Series.
Layout
ISP HEADER (J1) is a connector for ISP programming.
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 8 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).
