In order to achieve the required performance, the SLAC Technical Innovation Directorate has developed a common hardware and firmware platform for beam instrumentation based on the ATCA crate format. We have designed a stripline and cavity BPM system based on this platform that is capable of measuring the beam position at full beam rate. The system will have a dynamic range between 1 pC to 300 pC. This paper will discuss the design of the BPM electronics, overall architecture and performance on LCLS-I.
