BL Ctrl V2: common questions

What microcontroller does the BL Ctrl V2 use?

The BL Ctrl V2 is built around the ATmega168-20A, from the AVR/Arduino family.

How big is the BL Ctrl V2 PCB?

The BL Ctrl V2 measures 40 × 20 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the BL Ctrl V2?

85 components, from 28 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the BL Ctrl V2 design files?

From the odobot/PCB_DESIGN repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the BL Ctrl V2 design in my own project?

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

Can I test firmware for the BL Ctrl V2 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.
