The FLIR Lepton LWIR Camera module is an 80x60 infrared imaging camera that has recently become available from Digikey for a reasonable price.
There is also a ~$40 breakout board available. However, I have put this breakout board design together hoping it will help others integrate this cheap thermal imager into whatever they may dream up.
The board is 25.4mmx25.4mm. It breaks out ground, input voltage, SPI, and I2C. I have also included the list of parts I used as a Digikey cart.
Long ago I tested this version and it worked fine using the PureEngineering software. I have not played with it much since.
However, recently I updated the board to fix previous issues (as discussed before) as well as add a small SMD reset button. Sometimes, the device must be reset to connect properly using the PureEngineering software and so I figured having a button would be neat.
I also made the board fit in 1 sq in for the heck of it. Good practice I suppose. The GitHub repo has been updated with the latest Eagle files.
I think next I will get this fabricated and test it out and perhaps write my own software.
Then, I would like to shrink down to 0402, 4 layers, and add an ARM coprocessor as PureEngineering has done to add to the capability with perhaps an sd card.
Well I got the boards back from OSHPark and they look good. However, I noticed I mislabeled the SPI pins. The correct order is MOSI MISO CLK CS GND VIN SDA SCL. I guess I shouldn't have rushed and tried to mimic the Pure Engineering breakout so closely.
I soldered up one of them and have tested for shorts. I accidentally dropped a blob of soldered onto the socket when I was soldering the header on and so I had to get creative with some wick to get the shorts out from underneath the socket. The blob shorted the MOSI and MISO pins to ground but I seem to have been able to remove it all.
I powered the board with a 3.3 V source and have good power at each regulator and no power where it shouldn't be.
Next, I plan on connecting the board to an A+ Raspberry Pi and seeing if I can get any images out of it using Pure Engineering's software.
I do not plan on purchasing another module and so I have two extra PCBs and sockets to go with them. All someone would need is the module, regulators, and passives to assemble them (~$190 from Digikey). Message me if you would be interested. I am willing to get rid of them for free or the cost of shipping.
