Sumario:A readout scheme has been designed for the plastic scintillator bars of the Baby-MIND detector modules. This spectrometer will measure momentum and identify the charge of 1 GeV/c muons with magnetized iron plates interleaved with detector modules. One challenge the detector aims to address is that of keeping high charge identification efficiencies for momenta below 1 GeV/c where multiple scattering in the iron plates degrades momentum resolution. A front-end board has been developed, with 3 CITIROC readout chips per board and up to 96 channels. Hamamatsu MPPCs type S12571-025C photosensors were chosen for readout of wavelength shifting fibers embedded in plastic scintillators. Procurement of the MPPCs has been carried out to instrument 3000 channels in total. Design choices and first results of this readout scheme are presented.
