Description and specs

The PureThermal OpenMV by GetLab is a co-designed collaboration product between GetLab and OpenMV to produce a high-end mixed color and thermal camera for professional applications. For sensors the board features a 5MP OV5640 camera module, a FLIR Lepton socket capable of supporting any FLIR Lepton, and the VL53L0X laser range finder to assist in drawing the thermal image on the color image using the right offset/scaling. Live video can be displayed on the 4.3” 800x480 IPS TFT capacitive touch LCD onboard, mirrored to an HDMI monitor, or streamed over WiFi via RTSP. Finally, the PureThermal OpenMV can be programmed like any OpenMV Cam in Python to make it do anything you like via the MicroPython API. The PureThermal OpenMV is the product you’ve been waiting for!

The PureThermal OpenMV is based on the OpenMV Cam H7 Plus by OpenMV. You program it with the amazing OpenMV IDE. It’s got TensorFlow support and can run Neural Networks, it can track colored objects, do person detection, and much more! For a complete description of all the functionality onboard and what can be done see the API. Here’s what’s onboard:
