the 8V to 60V DC-in connectors. Note that while there are two DC-in connectors,
only one should be used at a time
.
The LTTP3(G2) comes preloaded with our own highly polished Linux distribution that
was derived from Red Hat.
The LTTP3(G2) is ideal for applications that require no human-machine interface but
need a substantial quantity of I/O lines and/or functions. The board is equipped with
four tiles offering a total of eight Tibbit module and eight Tibbit connector sockets.
These can be used to create TPS configurations with up to four full serial ports, up
to 16 relays, or up to 32 control lines, such as opto-inputs, PWMs, or open-collector
outputs. While this may seem like a step down from the I/O capabilities of the
LTPP3, consider that the LTPP3(G2) directly incorporates most interfaces and even
the power supply, thus reducing the number of Tibbits typically needed in a user's
application.
The LTTP3(G2) can be used as a bare board or assembled into a
