XM250 Carrier
Design of carrier board is simple. It requires only:
- 3.3 V supplied to module
- Line drivers depending upon your individual I/O requirements
Three options for carrier boards:
- Design your own
- Let us design a carrier based upon your I/O requirements, physical
dimensions with the required backplane or mezzanine bus interface
- The CR250 Evaluation Carrier can be used as a design reference
or as a target board
