Expansion Connectors (6-pin headers)
The Basys2 board provides four 6-pin
peripheral module connectors. Each connector
provides Vdd, GND, and four unique FPGA
signals. Several 6-pin module boards that can
attach to this connector are available from
Digilent, including A/D converters, speaker
amplifiers, microphones, H-bridge amplifiers,
etc. Please see
for more
information.
