Shown assembled with an SD card (card not included )

The 3.3v AVR_SD3 development board includes an AVR163L (or optional Mega32L ). The SD socket can also use MMC cards. Includes a standard DB9 RS232 connector for I/O.The AVC mcu can be programmed ‘in-circuit’ by using one of Atmel’s ISP programmers. All the AVR pins are available at (standard 0.1” spacing).

The AVR_SD3 is a very compact 3.3v AVR controller board with an SD/MMC card socket. It can work with most 40 pin AVR-L mcus such as the can use a Mega323L, Mega163L, Mega16L, Mega32L or a AT90LS8535 .Other “L” series AVRs can also be used with 40 pin carrier boards. The board has a standard Atmel 6 pin ISP programming header. It can be programmed using Atmels serial ISP hardware which is also compatible with the BascomAVR compiler. The board has a Max3232 RS232 IC, an I2C eeprom, 4mhz resonator, 3.3v Regulator, and a reset switch.
