tCam-Mini

Stacks Image 5
tCam-Mini is based off of on-going work on tCam. It is designed to make radiometric data from a Lepton 3.5 thermal imaging module available via Wifi for remote access. It is supported by a desktop application, simple web server and python library.

tCam-Mini is open-source hardware and software. The design and documentation may be found here. Its development has been documented on hackaday.io. Assembled, tested units are available for purchase from Group Gets. Please contact me for more information.
tCam-Mini is comprised of two components.
  1. Hardware design based around Flir Lepton 3.5 and an ESP32 micro-controller. The hardware design may also be hand-built using off-the-shelf breakout and development boards.
  2. Firmware for the ESP32.
