USB Model
Mini USB Connector
The LVK204-25-USB comes with a familiar Mini USB Connector to fulfill both communication and power
needs. The standard MiniB style header can be connected to any other USB style using the appropriate
cable. Most commonly used with a PC, this connection creates a virtual com port that offers a simple
power solution with a familiar communication scheme.
Alternate USB Header
Some advanced applications may prefer the straight four pin connection offered through the Optional
Alternate USB Header. This header offers power and communication access in a simple interface
package. The Optional Alternate USB Header may be added to the LK402-25-USB for an added charge as
part of a custom order. Please use the Contact section to request more information from the friendly
Matrix Orbital sales team.
Alternate Power Connector
The Alternate Power Connector provides the ability to power the LVK204-25-USB using a second cable.
The Tyco 171825-4 style header is particularly useful for connecting to an unmodified floppy power
cable from a PC power supply for a simple bench power solution.
