The TSC2111EVM is designed to easily interface with multiple control platforms. Samtec part numbers
SSW-110-22-F-D-VS-K and TSM-110-01-T-DV-P provide a convenient 2x10-pin dual-row header/socket
combination at J4 and J5. These headers/sockets provide access to the digital control and serial data pins
of the device. Table 5 summarizes the digital interface pinout for the TSC2111EVM.
