Introduction
The ECP5™ Versa Development Board allows designers to investigate and experiment with the features of the
ECP5 Field-Programmable Gate Array. The features of the ECP5 Versa Development Board can assist engineers
with rapid prototyping and testing of their specific designs. The ECP5 Versa Development Board is part of the
ECP5 Versa Development Kit. The guide is intended to be referenced in conjunction with demo user guides to
demonstrate the ECP5 FPGA.
