RileyLink Hardware

  • board.sch - circuit schematic
  • board.brd - pcb design file
  • bom.csv - materials list
  • case_bottom.stl - 3d printer model for case bottom
  • case_top.stl - 3d printer model for case top

Order the PCB from OSH Park:

RileyLink v1.0

Components

The bom.csv file contains a list of parts and quantities along with their Digikey part number.

PCB Assembly

A stencil for the PCB can be obtained at a reasonable price from OSH Stencils. Just upload the .brd file and accept the default mappings.

You will have to look at the schematic and the board design in Eagle to know where the parts go, and how they are oriented.

I use a hot-air rework station to flow the solder paste, but you could use a toaster oven setup as well.

Assembled Board

Case

I created a case using Tinkercad, a great tool.

3D Printed Case

The case is designed to hold an 850mAh Lipo. That battery lasts a day or so when the RileyLink is constant listen mode. It should last longer if the firmware uses a duty cycle that's less than 100%.

Case Fitting

Note: there’s an issue I have with the case that I haven’t fixed yet; the board in the case can rotate a bit so that the usb port doesn’t line up with the hole. If stick a small something (like those sticky pads that keep cabinet doors from slamming) to the top of the usb port, that fixes the issue.

868MHz (EU) version

Since the firmware allows changing of the frequency, and most people are using the 915Mhz antenna successfully with 868Mhz pumps, a custom RileyLink is not needed.
