THERMAL IMAGING // HANDHELD OLED REFERENCE DESIGN

FLIR Lepton Pocket Thermal Camera Reference Design

The FLIR Lepton Pocket Demo Camera is a self-contained handheld thermal imager designed by Pure Engineering. It pairs an Atmel SAMD21G18A 32-bit Arm Cortex-M0+ microcontroller (Arduino Zero architecture) with a 96x64 color OLED display, a 120 mAh LiPo battery, and a FLIR Lepton LWIR camera core.

Architecture & Technical Specifications

Hardware Architecture & Features

  • Atmel SAMD21G18A Arm Cortex-M0+ microcontroller at 48 MHz with native USB bootloader.
  • 0.95-inch 96x64 16-bit color SSD1331 OLED display rendering live thermal frames at 9 Hz.
  • Integrated 120 mAh rechargeable lithium-polymer battery (35 to 45 minutes continuous runtime) and USB charger.
  • Compact 3D-printable enclosure (42 x 28 x 19 mm, 24 g total mass) with slide power switch and palette button.

Firmware, Software & Integration

  • Programmed through the Arduino IDE using the Arduino Zero native USB port and open-source Lepton libraries.
  • Single pushbutton cycles through color palettes or triggers manual flat-field correction (FFC).
