The XPand1205 is a low-cost, flexible development platform, supporting up to eight 0.8 in. or 1.0 in. pitch conduction-cooled VPX (VITA 48.2) modules. It provides 650 W of total simultaneous power, which can be distributed as up to 40 A on 12 V, up to 40 A on 5 V, and up to 20 A on 3.3 V. The heat from the internal conduction-cooled modules is conducted to sidewall exchangers, where it is dissipated to the ambient environment by forced-air cooling. This efficient thermal design allows up to 70 W of power dissipation per slot at 30°C ambient, while maintaining 70°C at the module’s thermal interface.
X-ES platforms like the XPand1205 provide a feature-rich solution for system development. Rear Transition Modules (RTMs) provide maximum I/O flexibility and rapid system prototyping. Power and reset LEDs are provided for system status, and a momentary push-button is provided for reset. VBAT can be sourced from the included VITA 62 supply, a coincell battery, or an external power source for ease of making current measurements. Switches allow configuration of the included VITA 62 power supply, as well as other I/O signals.
The XPand1205 is currently available for purchase in several rapid-development standard configurations. Custom configurations of modules, RTMs, and backplanes are also available utilizing X-ES and third-party components.
