The ESPBoy was first built as a hackable open-source game engine and handheld console for educational purposes. However, it’s also a platform that can readily support all kinds of other uses. You can even turn the humble handheld device into a working walkie talkie.

The build relies on adding a SA868 transceiver module to the ESPBoy, along with a microphone, speaker, audio amplifier and antenna as supporting hardware. It then relies on the ESPBoy’s existing screen and buttons as a user interface for the radio. Assembled appropriately, it can then be used as a very basic and barebones walkie talkie for voice communication.

The ESPboy is open-source (most software is under MIT license) and open-hardware (CERN license) project, and is a science, technology, engineering, and mathematics [STEM] learning platform which encourages and enhances creativity, imagination, and ingenuity through project-based learning and reverse engineering. ESPboy is ideal to learn game development, internet of things, start programming, understand how gadgets work, and try robotics basics all with the community help.
