AVR DAUGHTER BOARD

About AVR

AVR is a family of microcontrollers developed by Atmel beginning in 1996 (later Microchip Technology acquired Atmel in 2016). These are modified Harvard architecture 8-bit RISC single-chip microcontrollers. AVR was one of the first microcontroller families to use on-chip flash memory for program storage, as opposed to one-time programmable ROM, EPROM, or EEPROM used by other microcontrollers at the time. AVR microcontrollers find many applications as embedded systems. They are also used in the Arduino line of open source board designs
