1 ZL10AVR Versatile Evaluation Board for AVR Microcontrollers Thank you for buying ZL10AVR evaluation board. We hope that the power and quality of our tool allow you to appreciate the advantages of AVR microcontrollers (AT90S, ATmega and ATtiny families). ver. 1.0

2 2 Introduction ZL10AVR is a versatile evaluation board designed for engineers and hobbyists who want to prototype systems based on AVR microcontrollers (AT90S, ATmega and ATtiny families in DIP8, DIP20, DIP28 and DIP40 packages). ZL10AVR is equipped with 7 DIP sockets suitable for most of AVR family microcontrollers. LEDs mounted near sockets indicate socket suitable for selected microcontroller. Developer has access to all microcontroller pins (only one microcontroller can be installed at the same time!), which are brought to gold-pin connectors. Board's configuration is complete and user can find on the board all of the following components: USB interface connector (for ZL1USB module), analog potentiometer, 8 MHz crystal oscillator, 4 LED displays, buzzer, RS232 interface with DB9F connector, 4x4 LED matrix, configurable keyboard (1x4 or 4x4 buttons), 8 LEDs, RC5 infrared receiver with TTL output, ISP connector and socket for LCD display (2x16 characters). Thanks to simple PLD logic (from Xilinx) incorporated on the board, most of integrated peripherals can be easy and comfortably connected to any port (PORTA, PORTB, PORTC or PORTD) available in microcontroller used in the application. The gold-pin headers provide access to easy connection of matrix keyboard and matrix display. Complete power supply integrated on ZL10AVR board eliminates the need for an external regulated power supply. ZL10AVR board comes with examples of Bascom programs.
