The package also include the fmc-bus driver, which is expected to be used by other carriers as well. ### [White Rabbit Switch - Software](https://www.ohwr.org/project/wr-switch-sw) Development of software for the White Rabbit switch, and in particular the embedded Linux system running in the ARM9 processor. [More info at the Wiki page](https://www.ohwr.org/project/wr-switch-sw/wiki) ### [FMC TDC 1ns 5cha](https://www.ohwr.org/project/fmc-tdc) An FPGA Mezzanine Card (FMC) with a Time to Digital Converter chip to perform one-shot sub-nanosecond time interval measurements. Commercially available. [More info at the Wiki page](https://www.ohwr.org/project/fmc-tdc/wiki) ### [SPEC box 1 Node](https://www.ohwr.org/project/spec-box-1n) The spec-box-1n allows to use a SPEC FMC carrier in stand-alone mode, not plugged inside a PC. An external 12 volt supply should be used to power the box. There is no forced ventilation in the box. [More info at the Wiki page](https://www.ohwr.org/project/spec-box-1n/wiki) ### [Simple PCIe FMC carrier (SPEC)](https://www.ohwr.org/project/spec) A simple 4-lane PCIe carrier for a low pin count FPGA Mezzanine Card (VITA 57). It supports the White Rabbit timing and control network. Commercially available. Linux and Labview drivers available for some mezzanine cards. [More info at the Wiki page](https://www.ohwr.org/project/spec/wiki) ### [FMC DIO 5ch TTL a](https://www.ohwr.org/project/fmc-dio-5chttla) FmcDIO5chTTLa is a 5-bit port digital IO card in FMC form-factor. Each single-bit port can be configured individually as input or output. The I/Os on LEMO 00 connectors are TTL compatible. Commercially available. [More info at the Wiki page](https://www.ohwr.org/project/fmc-dio-5chttla/wiki) ### [FMC ADC 125M 14b 12ch - DAC 1250M 16b 2ch](https://www.ohwr.org/project/fmc-adc125m14b12ch-dac1250m16b2ch) The fmc-adc125m14b12ch-dac1250m16b2ch (fmc-dad) board is a 12 ch ADC/ 2 ch DAC channels board using FMC HPC and QSE connectors It has been designed for system requiring a feedback loop mechanism with precise timing, such as the tunning of RF cavities. [More info at the Wiki page](https://www.ohwr.org/project/fmc-adc125m14b12ch-dac1250m16b2ch/wiki) ### [White Rabbit Starting Kit](https://www.ohwr.org/project/wr-starting-kit) This project guides new users to start in the White Rabbit “World” with simple experiments. The starting kit uses two SPEC + FMC-DIO cards. Each node allows basic operations such as input timestamping or programmable output pulse generation. Additionally, specific software and gateware layers allow to use it as a standard network interface card implementing the White Rabbit technology functionalities. ### [Wishbone Serializer Core](https://www.ohwr.org/project/wb-serializer-core) A transparent Wishbone bridge between two FPGAs using high-speed serial links. *This project is on hold.** [More info at the Wiki page](https://www.ohwr.org/project/wb-serializer-core/wiki) ### [White Rabbit Network Interface Card](https://www.ohwr.org/project/wr-nic) A White Rabbit compliant Network Interface Card (NIC) based on the [SPEC](https://www.ohwr.org/project/spec/wiki) and the [DIO FMC](https://www.ohwr.org/project/fmc-dio-5chttla/wiki).
