Flir Lepton 3.5 Breakout Board Options

Regarding the products, SKU: (1) Pure Thermal 2 Board, DEV-14670 and (2) Flir Lepton Camera Breakout Board v2.0, PN: 250-0577-00 and also seen in KIT-15948

I know I want the Flir Lepton 3.5, I don’t know whether I want the Pure Thermal 2 or Breakout Board v2.0.

I have been investigating differences between the capabilities of these breakout boards and am just about ready to purchase the Flir Lepton 3.5 and one of these modules/boards. Some clear differences among the boards I’ve noticed include PureThermal 2 having on board image processing, computer connectivity via USB, and open source firmware for the on board microcontroller chip. I’m interested in learning if there are additional differences aside from price? Furthermore I was interested in learning how the radiometry data is stored (array?), and whether that radiometry data can be pulled over the i2C pins (SDA & SCL)? Lastly I was wondering if these boards impact radiometric accuracy of the Flir Lepton 3.5 camera module in any way? (it seems like no they do not, as both support the radiometry feature)

Ultimately I am looking to interface the Flir Lepton Camera with a Teensy microcontroller, do I gain any potential benefit from utilizing the PT2 rather than the Breakout Board v2.0?

I look forward to hearing back, thank you in advance for the help.

Greeting, thanks for asking about these.

Both boards submit the radiometry as a 14-bit pixel data . Yes, the Pure Thermal 2 board allows to pull the data streams over i2c…in general, it simplifies interfacing with the a microprocessor, along with allowing Device Firmware Upgrade (the STM32 ARM MCU) over USB, and ability to debug via JTAG through a 6-Pin plug-of-Nails port using a Tag-Connect TC2030-IDC-NL, an ARM20-CTX, & ST-Link V/2.

The metal shielding around the camera port provides the interference reduction, so that probably isn’t a worry.

We offer the Pure Thermal 2 to make your projects go more smoothly - switching your setup on-the-fly is a MUCH less involved process with these tools it offers.

Hope this helps!
