What microcontroller does the Mini-BT-Pcb-328P use?

The Mini-BT-Pcb-328P is built around the ATmega328P-AU, from the AVR/Arduino family.

How big is the Mini-BT-Pcb-328P?

The Mini-BT-Pcb-328P measures 55 × 35 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Mini-BT-Pcb-328P?

48 components, from 33 distinct parts. The full bill of materials is listed on this page.

Where can I download the Mini-BT-Pcb-328P design files?

From the d-diot/Mini-BT-Pcb-328P repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Mini-BT-Pcb-328P design in my own project?

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

Can I test firmware for the Mini-BT-Pcb-328P 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.
