Page 6: Development Board Overview
Development board overview The EasyAVR v8 development board features a clean and intuitive layout, allowing the user to instantly understand how to set it up and how to easily tune it according to needs. The development board is divided into several sections, arranged so that all the related interactive components such as switches, buttons, indicators, and connectors, are logically positioned and grouped together. - Page 7 ™ www.mikroe.com The EasyAVR v8 development board is equipped with two display connectors, located in the middle section of the board. One connector is a 1x16 pin header used for connecting a character-based LCD in 4-bit mode. The second display connector is a single row 20 pin header, which supports monochromatic GLCD and EasyTFT board.

Figure 7: Main board with MCU socket section view MCU sockets As previously mentioned, the EasyAVR v8 development board supports all 8-bit AVR MCUs in DIP package type. There are eight different sockets, ranging from DIP8 (8-pin DIP socket), up to DIP40 (40-pin DIP socket). All DIP sockets are grouped in the lower left area of the board (1). -
Page 19: Vcap And Vcc
Crystal oscillator AVR microcontrollers can use either built-in (internal) or quartz-crystal external clock for the purpose of providing clock signal source. The EasyAVR v8 contains one quartz- crystal socket for all microcontroller sockets. DIP40A and DIP40B sockets are directly connected to quartz-crystal socket unlike DIP28A/B, DIP20A/B, DIP14 and DIP8 sockets which are connected to it through the selection switches (SW10, SW19 and SW22). -
