The last few days, we tryed to chose components for SaMoRa. We find a ADC for video and we did some research about god eyes video camera (especialy to understand the ouput format). So we try to chose a RF antenna to send/receive video from trains to central card. But it’s very difficult to chose it because many antennas use modulation and we should be sure that we will be able to demodulate the signal. After we chosed the RJ45 wire for central card. And we performed the architecture. we look for to put an fpga to do a part of the video treatment and we finished to undertand bus-CAN protocol.
To conclude, choice of components it’s very important, it’s the base of all our work.
