Board Specifications
Figure 10 shows a detailed mechanical drawing of the SPT711xPFCE. These dimensions conform to the
CMC standard length and width dimensions. Board height varies according to the components on the
board and choice of CMC connector height. Estimated board height is 13.5 mm unless both sets of CMC
connectors are populated. If CMC connectors are populated on both sides of the board, the estimated board
height is 24 mm.
