The focal-plane camera on the Rockets for Extended-source X-ray Spectroscopy (tREXS) is a large-Area detector array that takes advantage of the large-format, 3-side-buttable design of the Teledyne e2v Vega-CIS113 CMOS sensor. This paper discusses the initial design of the focal plane camera, results from testing that identified read noise performance issues, mechanical and electrical challenges of this initial design, and supply chain problems. The changes to the focal plane camera that were made due to these challenges are then presented, along with the final flight camera that has been designed to optimize noise performance and be able to be built within the schedule constraints of the tREXS mission.
