About the Capstone ece4900 PCB

Capstone ece4900 is an open source ESP32 PCB design by gworkman, published on GitHub. It is a 4-layer board measuring 68.6 × 62.2 mm, with 25 components from 20 distinct parts.

Its main chip is the ESP32-DEVKITC, from the ESP32 family. Other key parts include the AP3429A, MPU-6050 and FDC2212. By type, the board carries 11 capacitors, 6 resistors, 4 ICs, 2 inductors, 1 connector and 1 diode.

It belongs with the sensors and iot & wireless designs in this gallery.

From the project

Capstone project for Team 7 at The Ohio State University Department of Electrical and Computer Engineering

The following tools are highly recommended: 1. VS Code, with the python extension installed 2. A serial port monitor, such as the one included with the Arduino IDE, the GNU utility screen, or the terminal emulator program PuTTY

Command | Arguments | Description | Example ------- | --------- | ----------- | ------- make flash | port | Flashes the micropython firmware to the ESP32 | make flash port=/dev/tty.usbserieal-14120 make list | port | Lists the files currently on the ESP32 | make list port=/dev/tty.usbserial-14120 make put | port, file | Loads a file from the local filesystem to the…

Capstone ece4900: common questions

What microcontroller does the Capstone ece4900 use?

The Capstone ece4900 is built around the ESP32-DEVKITC, from the ESP32 family.

How big is the Capstone ece4900 PCB?

The Capstone ece4900 measures 68.6 × 62.2 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Capstone ece4900?

25 components, from 20 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 Capstone ece4900 design files?

From the gworkman/capstone-ece4900 repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Capstone ece4900 design in my own project?

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

Can I test firmware for the Capstone ece4900 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.
