Description:

We offer you more flexibility by the development. By means of quartz socket it is possible to choose another frequency easier and faster. External SDRAM solves the saving problem, if the internal 8K Bytes SRAM is not enough. Due to Jumper configuration of SDRAM there are following setting possible: ON/OFF switching of external SDRAM by hand or with an I/O Pin of the controller. All pins of controller are connected with the pins of module and positioned in the logical order, that makes the development work easier. The circuit of the module is built on the recommendation of the manufacturer: SDRAM, MicroSD card slot, A/D converter, reset, ISP, JTAG, RS232. Jumper configuration helps you to make the right settings. There are following options for power supply to your choice: external voltage of 3.3 V or external voltage between 5 – 12 V. We offer you a very simple installation and use of AVR-Module for the beginner as well as for the advancer.
