Atmel AT88CK109BK8 daughterboard
1. Introduction
Atmel® AT88CK101BK8 is a daughterboard that interfaces with a mcu board via a 10-pin header. The
daughterboard has two 8-pin SOIC sockets which can support HOST and CLIENT development with an
Atmel ATSHA204 device. This kit uses a modular approach, enabling the daughterboard to connect
directly to an STK series AVR development platform to easily add security to applications. An optional
adapter kit is also available when the 10-pin header on the daughterboard requires a different pinout. The
AT88CK109BK8 is sold with the Atmel AT88Microbase to form the Atmel AT88CK109STK8 starter kit. The
AT88Microbase AVR base board comes with a USB interface that lets designers learn and experiment on
their PCs.
