## Description

**FLIR** features the latest FLIR Lepton 3.0 longwave-infrared (LWIR) camera core, get two times the resolution and 4x the pixels of the previous 2.x generation

FLIR is covered by a 3D printing case, makes it a perfect functional bottom for non-contact temperature measurement, compatible with M5Core and can be controlled via I2C protocol.

The effective image generate by the Lepton sensor is 160×120, but you can process the image thru program and display a different resolution.

**Note:** If it worked for long hours, Lepton will heat up a little. But the output image is not affected.

## Product Features

- 160×120 Effective Pixels
- Lepton Low operating power — 150 mW (operating), 650 mW (during shutter event), 5 mW (standby)
- Field of view: 56°, with shutter
- Lepton Input Supply Voltage: 1.2V，2.8V，2.5V - 3.1V IO
- Fast imaging time (< 0.5 second)


## Include

- 1x FLIR

## Applications

- Car engine failure check
- Building dehumidification insulation sealing test
- Industrial furnace inner wall refractory crack
- Outdoor observation of animals at night

>1.EasyLoader is a simple and fast program burner. Every product page in EasyLoader provides a product-related case program. It can be burned to the master through simple steps, and a series of function verification can be performed.

>2.After downloading the software, double-click to run the application, connect the M5 device to the computer via the data cable, select the port parameters, and click **"Burn"** to start burning.

?>3.The CP210X (USB driver) needs to be installed before the EasyLoader is burned. [Click here to view the driver installation tutorial](en/related_documents/M5Burner#install-usb-driver)
