TRB module is a multi-purpose Trigger and Readout Board with on-board DAQ functionality developed for the upgrade of the HADES experiment. It contains single computer chip (Etrax) running Linux and the 100 Mbit/s Ethernet interface. It has been orginally designed as the 128-channel Time to Digital Converter based on the HPTDC chip from CERN. The new version of TRB contains 2 Gbit/s optical link and interface connector (15 Gbit/s) implementing the add-on card concept and making the board more flexible. Moreover, FPGA chip (Xilinx, Virtex 4 LX 40) and TigerSharc DSP provide new computing resources which can be used to run on-line analysis algorithms. The TRB is proposed as a prototype of base readout module for the planned detector systems PANDA and CBM at the future FAIR facility at GSI-Darmstadt.
