An **[illustrated assembly guide](https://github.com/maxritter/DIY-Thermocam/raw/master/Documents/AssemblyGuide_04.pdf)** will lead you through the **process** of **constructing** the device, **step-by-step**. You should have soldered at least **one small project before**, but with that experience you **should be fine**.

On the **part side**, you need the **components** from the **support package** and the **missing parts** from the **other parts list** below.

The DIY-Thermocam works with the **FLIR Lepton2.x** (**80 x 60**) and the **FLIR Lepton3.x** (**160 x 120**) LWIR sensor, including the **radiometric versions** (**Lepton2.5** only at the moment). The **hardware revision** is **detected automatically** by the firmware **on startup** and you can **change** the sensor just with your **fingers**.

The **Lepton2.0** and **Lepton3.0** sensors do **not** have in an **internal calibration**. An **external spot sensor**, the **MLX90614** is used to generate a **transfer function** for raw values to absolute temperatures conversion. When using a **radiometric Lepton** (**Lepton2.5** only at the moment), the **spot sensor** is **not required**.
