To ensure the extremely low emittance of electron beams, it is necessary to provide more accurate beam position measurement. Based on the BPM of the 3rd generation light source (SSRF), the design of button BPM for a diffraction-limited storage ring in the low-energy region of the 4th-generation light source is presented in this paper. Here we have focused on optimizing the BPM in terms of the basic structure sizes, the wakefield caused by electron beam transport and the voltage signals picked up by the electrodes, etc. The optimization improves the measurement resolution of BPM together with matching the requirements of beam position measurement proposed by the low energy storage ring.
