ESPboy STEM is an indie project with unique handmade gadgets designed to help enthusiasts learn/improve IT/IoT skills and promote engineering creativity.
An interesting hobby for you and your children, an opportunity to learn programming, neo-retro games development, MCU and IoT technology, electronics and digital device creation.
This is a simplified version of the original ESPboy1/ESPboy2 with all the through-holes and cheap parts, designed to help beginners make their own ESPboy!
ESPboy easy DIY version has a slightly simplified circuit compared to ESPboy1/ESPboy2, but is 99.9% compatible with them, however this circuit uses large through-holes components which are very easy to solder, especially for beginners and almost impossible to mistake.
The screen brightness control is removed, a buzzer is put in place of the speaker, the protection on the LEDs is removed, but a volume control is added.
Overall it is a complete ESPboy with an expansion connector, where the AppStore(available directly from the device)/WebAppStore and all ESPboy released software and hardware modules should work.

- Battery holder for 3xAAA
