Evaluation Board for dipAVR Mini-module

===== Introduction =====
ZL8AVR is a versatile evaluation board designed for engineers and hobbyists who want to prototype systems based on AVR ATmega microcontrollers. ZL8AVR is prepared to operate with dipAVR mini-modules (ZL7AVR, ZL12AVR). Board's configuration is complete and user can find on the board the following components: USB interface connector (for ZL1USB module), RS232 interface with DB9F connector, simple keyboard (4 buttons), 8 LEDs, JTAG connector and socket for LCD display (2x16 characters). ZL8AVR board comes with examples of Bascom programs.

===== Features =====
* RS232 interface (with level converter and DB9F connector)
* JTAG connector
* Built-in 5 V voltage regulator
* Socket for LCD 2x16 character display (LCD1602 module)
* 8 LEDs
* MMC Flash card connector
* 4 microswitches
* Socket for USB interface (ZL1USB module)
* Prototype design area
* USB (5 V) or external (9...12 VDC) power supply

===== Complete schematic =====
Circuit diagram is shown on Fig. 1. Recommended supply voltage is 9 VDC (9...12 VDC) connected via standard power jack or USB_PWR connector (selectable by JP8). Polarisation of input voltage is not important – bridge rectifier guarantees proper board operation in both cases.
