Hi all, I wanted to ask here that do anyone has experience designing a PCB for notecard/s? I want to know about antenna parameters and requirements of Antenna design for GPS and Cellular module on Notecard. I was refering to the documentation > **[Notecard Datasheet - NOTE-NBGL - IoT Connectivity at Blues](https://dev.blues.io/datasheets/notecard-datasheet/note-nbgl/)** > > Technical description and full datasheet for all Notecard SKUs. Notecard is a low-power system-on-module with integrated cellular, Wi-Fi, LoRa, and/or satellite connectivity for IoT applications. Thanks. ---

Hi @ujur007, I’m sure others can provide more guidance, but the first thing I tell people is to model PCB antenna placement around the Notecarrier A (which uses an Ignion antenna): > **[Diagnosing Cellular Connectivity Issues - Blues Developers](https://dev.blues.io/guides-and-tutorials/notecard-guides/diagnosing-cellular-connectivity-issues/#ensure-no-antenna-signal-interference)** > > A guide for diagnosing and resolving a variety of common LTE Cat-1, LTE-M, and NB-IoT cellular connectivity issues with the Notecard. ![image](https://us1.discourse-cdn.com/flex020/uploads/blues/original/1X/a5e62a4901219f5f49dc8dd69abc58ef9ec03bda.jpeg) ---

Hi @RobLauer Meanwhile, I also have a question about the M.2 connector. Looking at the link below and comparing it with the Notecard/carrier I have I find that there the footprint seems different. BTW, I also checked the hardware files provided by Blues and there it is the same connectors. So please clerify > **[MDT420E01001 | Digi-Key Electronics](https://www.digikey.in/en/products/detail/amphenol-icc-fci/MDT420E01001/5810336)** > > Order today, ships today.

Hi @ujur007, You need an M.2 Key E connector. This is the one we source for our Notecarriers: > **[MDT420E03001 | Digi-Key Electronics](https://www.digikey.com/en/products/detail/amphenol-icc-(fci)/MDT420E03001/5810372)** > > Order today, ships today. MDT420E03001 – 67 Position Female Connector M.2 (NGFF) Mini Card Gold 0.020" (0.50mm) Black from Amphenol ICC (FCI).

Thanks @RobLauer That indeed seems the right one. ☺
