FMC nanoFIP
FMC-nanoFIP is an 'Agent' (slave) interface card for the WorldFIP network in an LPC FMC form-factor.

The main components of the FMC-nanoFIP board are:
- The nanoFIP rad-tol FPGA that acts as a client node in the communication over the WorldFIP fieldbus.
- The FielDrive bus driver and FieldTR insulating transformer, both developed and sold by the company Alstom.
- A Lemo-0 connector, optionally used for the reception of an input synchronization trigger pulse, usually from CERN's timing board CTRI.
- An EEPROM chip, loaded with IPMI FRU information, and a 1-wire thermometer-unique-id-chip, so as to comply with the FMC standard.
The schematics of the board, drawn in KiCad, are available at CERN's EDMS.
Different board executions exist depending on the WorldFIP communication speed: 31.25kbps, 1Mbps, 2.5Mbps, and 5Mbps; a set of ten components differentiates the board executions.
