About the Esp32s3-usb imu board

Esp32s3-usb imu board is an open source ESP32 PCB design by kanishqtanwar35-hub, published on GitHub. It is a 2-layer board measuring 65 × 45 mm, with 33 components from 22 distinct parts.

Its main chip is the ESP32-S3-WROOM-1-N8R2, from the ESP32 family. Other key parts include the CH340C, AP2112K-3.3 and ICM-42688-P. By type, the board carries 10 capacitors, 10 resistors, 4 ICs, 4 diodes, 2 transistors and 1 connector.

It belongs with the sensors, usb & debug tools and dev boards & breakouts designs in this gallery.

From the project

2-layer ESP32-S3 board with onboard CH340C USB-UART (auto-reset) and ICM-42688-P IMU. KiCad schematic, layout, gerbers and bring-up firmware.

A small 2-layer ESP32-S3 dev board where the programming circuit and the motion sensor are designed in at chip level instead of plugged in as breakout modules. You plug in USB-C, it enumerates as a serial port, and esptool can flash it without touching a button.

Started as a hardware design assignment. The original problem statement is in assignment/problemstatement.pdf`.

Esp32s3-usb imu board: common questions

What microcontroller does the Esp32s3-usb imu board use?

The Esp32s3-usb imu board is built around the ESP32-S3-WROOM-1-N8R2, from the ESP32 family.

How big is the Esp32s3-usb imu board?

The Esp32s3-usb imu board measures 65 × 45 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Esp32s3-usb imu board?

33 components, from 22 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 Esp32s3-usb imu board design files?

From the kanishqtanwar35-hub/esp32s3-usb-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 Esp32s3-usb imu board design in my own project?

The repository has no license, so all rights stay with kanishqtanwar35-hub. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Esp32s3-usb 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.
