About the IMU-board

IMU-board is an open source ESP32 PCB design by MohamadAminGhanoum, published on GitHub. It is a 2-layer board measuring 38.2 × 50.1 mm, with 21 components from 14 distinct parts.

Its main chip is the ESP32-S3-WROOM-1, from the ESP32 family. Other key parts include the ISM330DHCX and AMS1117-3.3. By type, the board carries 8 capacitors, 6 resistors, 3 ICs, 2 switches, 1 connector and 1 diode.

It belongs with the sensors designs in this gallery.

From the project

planning to make a module that has small sensors on the pcbs, which will give me motion data, which i will track and recieve on either my phone or computer using the usb-c

IMU-board: common questions

What microcontroller does the IMU-board use?

The IMU-board is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the IMU-board?

The IMU-board measures 38.2 × 50.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the IMU-board?

21 components, from 14 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 MohamadAminGhanoum/IMU-board 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 MohamadAminGhanoum. 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 ESP32 firmware against it before you order a PCB.
