Frequently Asked Questions - Lepton FLIR
How do I connect the FLIR Lepton module to a microcontroller?
The FLIR Lepton communicates via a SPI interface (3-wire or 4-wire). You will need to wire the CS, MOSI, MISO, and CLK pins, typically operating at 3.3V logic. Refer to the datasheet for detailed pinout.
What is the resolution of the Lepton thermal camera?
The standard Lepton module has a resolution of 80x60 pixels. Some variants like Lepton 3.0 offer 160x120 pixels.
Can I measure temperature with the Lepton?
Yes, the Lepton can measure temperatures after calibration. It outputs raw pixel values; you need to apply a temperature conversion formula provided in the datasheet. Accuracy is typically ±5°C or better with spot calibration.
What is the operating voltage and current?
The recommended supply voltage is 2.8V to 3.1V. Typical current consumption is around 50 mA, giving a power dissipation of about 150 mW.
Does the Lepton module come with a lens?
Yes, the Lepton includes a built-in wafer-level lens with a fixed focus. The standard field of view is approximately 57° horizontal by 44° vertical.
What is the frame rate of the Lepton?
The Lepton can output images at up to 8.7 Hz (frames per second) for the 80x60 model. The 160x120 model runs at a lower frame rate, typically 8.7 Hz as well.
How do I clean the Lepton lens?
Use a soft, lint-free cloth to gently wipe the lens. If needed, moisten the cloth with distilled water. Avoid alcohol or other solvents as they may damage the lens coating.
What is the temperature range the Lepton can detect?
The Lepton can detect temperatures approximately from -10°C to 400°C (without high gain mode). Extended range models may go higher.
Is the Lepton module RoHS compliant?
Yes, the FLIR Lepton module is RoHS compliant (Restriction of Hazardous Substances).
Where can I find the full user manual?
The complete user manual and datasheet can be downloaded from the FLIR website or from notice-facile.com. The manual includes pinouts, communication protocols, and calibration details.
