Breakout board for InnoComm Sigfox module SN10-12

InnoComm SN10-12 Sigfox Breakout Board

This breakout board connects your Arduino, Raspberry Pi and other devices to the Sigfox IoT network for low-power, long-range communications. The board uses the InnoComm SN10-12 module to connect to the Sigfox network. The interface between the device and the breakout board is based on SPI with 8 pins (3.3V, GND, CS, SDI, SDO, SCLK, AK, RST). A U.FL antenna and a Sigfox network subscription are required.

• Autodesk EAGLE board and schematic for InnoComm SN10-12 Sigfox Breakout board (Sigfox Zones RCZ2 and RCZ4) are in innocomm-sigfox-breakout.brd and innocomm-sigfox-breakout.sch

• The PCB design uses 2 layers: Top (layer 1), Bottom (layer 16).

• Formatted for Seeed Fusion PCB Assembly service, so that you may submit the files from this repository and order the breakout board fully assembled with the onboard components, including the InnoComm Sigfox module:
  https://www.seeedstudio.com/fusion.html

• All components sourced from Seeed Open Parts Library (except for InnoComm module) for quicker PCB assembly by Seeed Fusion:
  https://www.seeedstudio.com/opl.html

• Seeed Open Parts Library for Autodesk EAGLE: (only for the components used)
  Seeed-Capacitor.lbr
Seeed-Connector.lbr
Seeed-Inductor.lbr
Seeed-Resistor.lbr

• SparkFun Library for Autodesk EAGLE was used for general symbols and components:
  SparkFun-Aesthetics.lbr
SparkFun-Boards.lbr
SparkFun-Connectors.lbr
SparkFun-PowerSymbols.lbr
  

• PCB layout was validated in Autodesk EAGLE with the Seeed Fusion Design Rules SeeedStudio_2layer_DRU_no_angle_20140221.dru

• PCB design was exported from Autodesk EAGLE to Seeed Fusion in Gerber RS-274X and Excellon (drill) formats using the CAM Processor Job Seeed_Gerber_Generater_2-layer.cam. To export:

  1. In EAGLE Board Editor, click File → CAM Processor

  2. At the top of the CAM Processor window, click the Load Job File icon. Click New CAM Job.

  3. Click Open CAM File. Select Seeed_Gerber_Generater_2-layer.cam.

  4. Click Export As ZIP

  5. Under Gerber → Options → Output Type, select Gerber RS-274X.

  6. Click Process Job. This creates a ZIP file that may be uploaded directly to Seeed Fusion.

• To export the Bill Of Materials (BOM) for uploading to Seeed Fusion:

  1. In EAGLE Board Editor, click File → Export Partlist. Enter partlist.csv as the filename.

  2. We will use the first 2 columns of partlist.csv:
     Part: Contains the Designator e.g. C1
Value: Contains 3 values - Description / Manufacturer Part Number / SKU (i.e. the Seeed Open Parts Library SKU number) like this: 33pf / CC0402JRNPO9BN330 / 302010000
     

  3. Open the file innocomm-sigfox-breakout-bom.csv in Excel. Populate the 3 columns: Designator, Manufacturer Part Number, Quantity like this:

     Designator,Manufacturer Part Number,Quantity
     C1,CC0402JRNPO9BN330,1
     C2,TAJC476K006RNJ,1
     U1,SN10-12,1
     ...
     

     We will provide a URL for Seeed Fusion to source for the InnoComm SN10-12 module.

  4. Save the CSV file for uploading to Seeed Fusion. Check innocomm-sigfox-breakout-bom.csv for the BOM that I have submitted to Seeed Fusion.
