Or is it completely compatible without the need to modify the PCB?</P><P>&nbsp;</P><P>Thanks!<A href="https://community.nxp.com/t5/forums/postpage/choose-node/true/attachments-key/0043819e-2bea-4415-8d48-6c208c41b44a/board-id/MCX#" target="_blank" rel="noopener"> HW-Open-Source</A>&nbsp;#i.MX8 mini</P> Mon, 19 Jan 2026 07:30:40 GMT https://community.nxp.com/t5/MCX-Microcontrollers/i-MX8Mimi-LPDDR4-ZQ0-and-ZQ1-ZQ-calibration-reference-design/m-p/2295741#M4672 Zack8 2026-01-19T07:30:40Z https://community.nxp.com/t5/MCX-Microcontrollers/i-MX8Mimi-LPDDR4-ZQ0-and-ZQ1-ZQ-calibration-reference-design/m-p/2296225#M4677 <P>Hi&nbsp;<a href="https://community.nxp.com/t5/user/viewprofilepage/user-id/252903">@Zack8</a>&nbsp;</P> <P>No need to connect R6.
