Nano Lambda: common questions

What microcontroller does the Nano Lambda use?

The Nano Lambda is built around the Arduino_Nano_Socket, from the AVR/Arduino family.

How big is the Nano Lambda PCB?

The Nano Lambda measures 22.2 × 47 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Nano Lambda?

70 components, from 43 distinct parts. The full bill of materials is listed on this page.

Where can I download the Nano Lambda design files?

From the chaosteam/Nano_Lambda repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Nano Lambda design in my own project?

The repository has no license, so all rights stay with chaosteam. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Nano Lambda 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.
