HotAirGun: common questions
What microcontroller does the HotAirGun use?
The HotAirGun is built around the Arduino_Nano_Socket, from the AVR/Arduino family.
How big is the HotAirGun PCB?
The HotAirGun measures 104.1 × 82.6 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the HotAirGun?
68 components, from 54 distinct parts. The full bill of materials is listed on this page.
Where can I download the HotAirGun design files?
From the raspibo/HotAirGun repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the HotAirGun design in my own project?
The repository has no license, so all rights stay with raspibo. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the HotAirGun without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
