Overview
VersaLogics SPX expansion modules provide a new level of economy and convenience for
routine I/O expansion. Their small size, low cost, and simplified system interface are possible
due to high levels of integration and miniaturization that were not previously available.
Unlike larger expansion formats such as PC/104, the extremely compact SPX format does
not require a stacking connector or a position in the expansion stack. Connected by a single
14-pin cable to any SPX-enabled base board, SPX expansion modules can be mounted in any
position, up to two feet from the host. The small (1.2” x 3.8”) SPX modules may optionally be
attached to the base board using PC/104 stand-offs.
Up to four SPX modules can be daisy-chained together to meet targeted I/O requirements at
a substantial cost and space savings. Typical functions available include:
8-channel Analog Input
16-bit Digital I/O
4-channel Analog Output
CANbus Controller
8-channel Solid State Switch
SPX modules can be used with baseboards (single board computers) that include an SPX
expansion connector. This includes products such as VersaLogic’s Python and Sidewinder
SBCs. SPX modules can also be used with other systems that include an SPI signaling
interface. Custom cabling and signaling restrictions may apply when connecting to generic
SPI signals.
All VersaLogic SPX modules are fully RoHS-compliant, and are backed by VersaLogic’s
standard two-year limited warranty. All SPX modules are rated for extended temperature
operation (-40º to 85ºC).
Like all VersaLogic products, SPX I/O modules are designed to support OEM applications
where high reliability and long-term availability are essential. From ease of application design-
in to a five year availability guarantee, their quality and longevity provide low-cost, long-term
solutions for demanding applications. SPX modules are manufactured to the highest quality
standards.
In addition to standard off-the-shelf modules, VersaLogic can design custom SPX modules
for a nominal fee.

Details
The SPX platform uses SPI signaling with a defined interconnect using a 14-pin
2 mm cable. This allows a single chip interface between the I/O device and the
SPX interface. The simplified system interface means that custom I/O functions
are inexpensive and straightforward to implement.
Multiple SPX modules, up to four per system, can be used at once. Modules
of the same or different I/O type can be daisy-chained together using a single
cable with multiple connectors. The modules are connected to the baseboard
via a 14-pin cable.
External I/O signals are typically connected directly to SPX modules via the on-
board screw terminals. The 14-pin SPX interface cable typically provides up to
500mA of fused +5V power for use by the connected modules.
Custom modules for most functions are very easy to develop on the SPX platform.
