About the Imu daq revA PCB

Imu daq revA is an open source RP2040/RP2350 PCB design by klimemam, published on GitHub. It is a 2-layer board measuring 38 × 46 mm, with 47 components from 27 distinct parts.

Its main chip is the RP2040, from the RP2040/RP2350 family. Other key parts include the ICM-42688-P, W25Q128JVSIQ, AP2112K-3.3 and USBLC6-2SC6. By type, the board carries 22 capacitors, 10 resistors, 5 ICs, 3 connectors, 2 switches and 2 diodes.

It belongs with the sensors designs in this gallery.

From the project

This is the original rev A form factor with the USB-C defect fixed — for re-ordering the small board variant. Derived from the canonical rev B design (../hardware/imu-daq.kicadpcb) by ../hardware/tools/makereva.py.

This is the original rev A form factor with the USB-C defect fixed — for re-ordering the small board variant. Derived from the canonical rev B design (../hardware/imu-daq.kicadpcb) by ../hardware/tools/makereva.py.

Status: DRC 0 violations / 0 unconnected (see drc-revA.rpt).

Order options are identical to rev B — see ../hardware/manufacturing/ORDERING.md (2-layer, 1.6 mm, ENIG, Economic PCBA, top side).

Imu daq revA: common questions

What microcontroller does the Imu daq revA use?

The Imu daq revA is built around the RP2040, from the RP2040/RP2350 family.

How big is the Imu daq revA PCB?

The Imu daq revA measures 38 × 46 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Imu daq revA?

47 components, from 27 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 daq revA design files?

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

Can I use the Imu daq revA design in my own project?

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

Can I test firmware for the Imu daq revA without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
