About the Imu board

Imu board is an open source AVR/Arduino PCB design by BUNPC, published on GitHub. It is a 4-layer board measuring 16 × 8 mm, with 10 components from 10 distinct parts.

Its main chip is the ATmega168A-MM, from the AVR/Arduino family. Other key parts include the ISM330DHCX. By type, the board carries 2 ICs, 2 connectors, 2 jumpers, 2 capacitors, 1 diode and 1 resistor.

It belongs with the sensors designs in this gallery.

Imu board: common questions

What microcontroller does the Imu board use?

The Imu board is built around the ATmega168A-MM, from the AVR/Arduino family.

How big is the Imu board?

The Imu board measures 16 × 8 mm, has 4 copper layers and is 0.8 mm thick.

How many components are on the Imu board?

10 components, from 10 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 Imu board design files?

From the BUNPC/NN24_25-Hardware-Firmware 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 Imu board design in my own project?

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

Can I test firmware for the Imu board 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.
