ELKS aka ESP Learning Kit Starter is a development board for the ESP32-S3 microcontroller. It's an educational tool for teaching electronics and embedded programming. We employ it ourselves in courses for beginners and advanced students.
It can be powered by a USB cable or power bank coupled directly with the board. This way you can take your ELKS with you anywhere and use it for your on-the-go projects.
Features:
- Conventional LEDs
- Buttons
- Potentiometers
- Buzzer
- Servo outputs
- Digilent PMOD connectors
With the support of Espressif Systems

Questions
How big is the ELKS PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ELKS use?
84 parts, built around the ESP32-S3. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the ELKS KiCad files?
From the RoboticsBrno/RB3206-ELKS repository on GitHub, at the commit this page was made from: the board is HW/ELKS/ELKS.kicad_pcb and its schematic HW/ELKS/ELKS.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ELKS design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
