Mini_AVR with USB is a small rapid prototyping board based on atmega 8 controller from AVR. Comes with inbuilt bootloader and hence eliminates use of external programmer. It can also be used with Arduino software. The board has additional pads for male connectors, with which the board can be fixed on a bread board!

Features

->

USB Interface CP2102: for communicating with the host computer.
LCD Interface:16 characters,2 lines.
Test Leds(2) and Switches(2).
Breakout for all Ports.
POT to test ADC.
Breakout to fix directly on breadboard.
Breakout +5v,Gnd and Vin.
Power Supply compatible with DC adapters.

Physical Features

->

Dimensions:65mm X 90mm.
1.6mm Glass Epoxy, FR4 PCB.
Wave Soldered
