 The [PureThermal 1](https://groupgets.com/manufacturers/groupgets-labs/products/pure-thermal-1-flir-lepton-dev-kit)
 is an embedded development platform for the FLIR Lepton thermal imager, created by
 GroupGets Labs. It is based around the STM32F4, a powerful ARM Cortex-M MCU by ST Microelectronics, and its
