Expansion Header

The MachXO Starter board includes two Samtec board-to-board connector footprints (connectors not included) for
expansion purposes. All MachXO I/O pins, JTAG signals and board voltages are connected to these pads. Refer to
Table 3 for MachXO connections to the expansion headers. Programming pins can be referenced in the Program-
ming Headers sections of this guide. Power connections are listed in Table 3.
Table 3. Expansion Connector Power Connections
The connectors are Samtec part number QTH-030-01-F-D-A. Mating connectors are Samtec part number QSH-
030-01. A mechanical drawing with placement dimensions is available from Lattice.
