AT88CK109BK3 HOST and CLIENT Sockets Compatibility
AT88CK109BK3 is supplied with two SOT23-3 sockets titled HOST and CLIENT. Since both
sockets have identical pinout’s, the AT88Microbase can physically accept a host or a client device
in either socket. Therefore, the AT88CK109BK3 can be configured for either a host-client or client-
client development.
