Do you have realized the communication between host and PN5180 correctly?</P> Mon, 24 Feb 2025 00:40:06 GMT KaiLi 2025-02-24T00:40:06Z https://community.nxp.com/t5/NFC/Troubleshooting-DIY-PN5180-NFC-Module-Schematic-and-Design/m-p/2049467#M12709 <P>I designed a DIY PN5180 NFC module using a design tool, but it is not detecting NFC cards. in order to troubleshoot, the schematic and component values need to be checked for possible errors. Since im new to NFC design, references such as the PN5180 Datasheet, AN11740 (Antenna Design Guide for NFC) Uploading my schematic, and <span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Screenshot 2025-02-23 164114.png" style="width: 999px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/325242i0C63E178A693D5C6/image-size/large?v=v2&amp;px=999" role="button" title="Screenshot 2025-02-23 164114.png" alt="Screenshot 2025-02-23 164114.png" /></span><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="ss.png" style="width: 999px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/325241i9DCCACFB19102E86/image-size/large?v=v2&amp;px=999" role="button" title="ss.png" alt="ss.png" /></span><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="ssss.png" style="width: 999px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/325240i214D0479353B14E2/image-size/large?v=v2&amp;px=999" role="button" title="ssss.png" alt="ssss.png" /></span>help identify any design mistakes and suggest improvements.</P> Sun, 23 Feb 2025 13:56:41 GMT https://community.nxp.com/t5/NFC/Troubleshooting-DIY-PN5180-NFC-Module-Schematic-and-Design/m-p/2049467#M12709 Hamdan420 2025-02-23T13:56:41Z https://community.nxp.com/t5/NFC/Troubleshooting-DIY-PN5180-NFC-Module-Schematic-and-Design/m-p/2049494#M12711 <P>Hello&nbsp;<a href="https://community.nxp.com/t5/user/viewprofilepage/user-id/246025">@Hamdan420</a>&nbsp;</P> <P>PN5180 needs a host to work properly, from your schematic, the design is not complete, so the NFC you mentioned can not detect the card.
