This work is devoted to the front-end readout electronics of the Silicon Tracking system (STS) for the BM@N experiment (Dubna, JINR). Its basic component is a module consisting of a double-sided microstrip CBM-type sensor, multilayer micro-cables and two front-end readout boards (FEB). The data acquisition system (DAQ) is designed to read in free-streaming mode with more than 600 000 channels. It has a bandwidth of about 300 GB/s and is operated in a magnetic field and in a heavily irradiated environment. The key element of the readout system is the unpacked integrated circuit STS-XYTER v.2.1. On its basis, prototypes of FEB have been developed and tested, and new versions have been created that fulfilled the current requirements. Mechanics, power supply and cooling have been worked out. Cable connections and adapters for connecting the module to external electronics have been developed and tested.
