Step 1

LoFi is expected to be delivered ready-to-use (prepopulated and preprogrammed). These instructions are for people that want to build LoFi themselves from scratch or are interested for curiosity. These instructions are expected to change as the project nears completion.
Download and decompress the PCB layout files from this project page.
2

Step 2

Go to https://www.oshpark.com/
3

Step 3

Open the PCB layout folder and locate desired PCB you'd like to have made. For example, LoFi-PCB-Layouts/Sender/LoFi-Sender-v7.zip. Drag that zip file onto the OSH Park web page to upload it.
4

Step 4

OSH Park will process the file and display it. Continue with their instructions to order the boards. Notice it is only $6 for three boards!
5

Step 5

Repeat steps 3-4 for any other LoFi boards you want. See the Read Me file in LoFi-PCB-Layouts for suggestions.
6

Step 6

Order the parts from your favorite supplier (commonly Mouser or DigiKey). For a complete part list, open the .rrpcb files in Copper Connection (http://www.robotroom.com/CopperConnection/) and choose Bill of Material from the Data menu.
7

Step 7

Solder the boards. There is nothing special about these parts. Although they are surface mount, they are no smaller than 0805 (US) and SOIC.
8

Step 8

LoFi is written in C using the open source GCC compiler built into the free Atmel AVR Studio IDE v6.2. Download and install AVR Studio if you haven't already.

Step 9

Double click on LoFi.atsln to open the LoFi solution in AVR Studio.

Step 10

In Project->Configuration Manager, make sure the solution is set to Release.
Then choose Build from the Project menu to compile the project.

I would also like to purchase some ready-to-go for humidity and temperature monitoring. Has anyone been able to build these out? Any guidance would be appreciated
