FMC carrier equipped with a Power PC embedded processor. In addition to the SPEC it has 2 gigabit Ethernet ports, one mini PCIe connector and USB 2.0 HS. It is supplied from a single 12V and runs Linux. The FPGA is configured from the processor and also interfaced using PCI Express x1 and a local bus. The system boots from on-board NAND or NOR flash memory.

It is a simple, low-cost measurement device equipped with GPS, GPRS modem, keyboard, display and LiOn battery. It can be also supplied/charged via a USB connector. It is enclosed in a nice-looking Hammond enclosure. It also has 3 RJ50 connectors that enable connection of various types of sensors. Each sensor can be connected using UART, I2C, SPI, 1-wire or analog interface. The device connects with a remote server which is also part of the development. We want to use them at Warsaw University of Technology to build a distributed network of sensors.

This project deals with the distribution of RF signals over a White Rabbit network. In particular, it describes ways of extracting the characteristics of an RF signal (I/Q, Amplitude/Phase...) using a WR sampling node and the way to distribute those characteristics through Ethernet frames and generate the RF on the receiving nodes.

The B-Train integrator is a 2 differential channel 2MSPS 18 bit ADC card in FMC (FPGA Mezzanine Card) format. It uses an LPC VITA57 connector. The gain can be set by hardware (default = 1). A gain & offset self-calibrating function is also implemented. This function uses a 1ppm 20-Bit DAC (AD5791) as a reference and can be programmed as a differential voltage source. The card also includes 8 input/output LVDS pairs and a 10-bit port digital IO where each single-bit port can be configured individually as input or output. The I/Os that are on micro-HDMI connectors are TTL or LVDS compatible.

The Peak Position Detector is a 2 differential channel 10MSPS 16 bit ADC (AD7626) card in FMC (FPGA Mezzanine Card) format. It uses an LPC VITA57 connector. The gain can be set by hardware (default = 41). Two general purpose 50MSPS 16-Bit DAC are implemented and can be programmed as a voltage source. The card also includes 6 input/output LVDS pairs and a 10-bit port digital IO where each single-bit port can be configured individually as input or output. The I/Os that are on micro-HDMI connectors are TTL or LVDS compatible.

The TimEX3 is a multipurpose compact PCI board designed to perform simple to medium complex logical functions. It is mainly used for the synchronization system of SOLEIL (signal duplication, top-up gating, etc.). This board is based on a Spartan-6 FPGA and PLX PCI9030 interface. It is designed with KiCad software, and released under CERN OHL License.

The GSI Timing Starter Kit is a functional snapshot of the eventual FAIR timing system, which is under active development. It demonstrates real-time coordination of two front-end equipment controllers. The product consists of a data master (Linux PC) which coordinates events, a timing master which synchronizes clocks (White Rabbit switch), and two front-end equipment controllers (either SPECv4 or SCUv2).

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.
