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.
