Layout, design and features …
The heart of our project is the ESP32-S3 dev board. It has 16MB flash memory, 8MB PSRAM and integrated W-LAN as well as Bluetooth 5 Low Energy. Boards with ESP32 processors are available in different variants. However, an overview and explanation of all variants would go beyond the scope of this workshop for beginners. As a beginner in microcontroller programming, you should always follow the descriptions in the templates exactly to avoid any (nasty) surprises later on.
The following picture shows the ESP32-S3 dual-core processor, which operates at 240 MHz. The rest button is located on the back right and there is also a socket for connecting an external W-LAN antenna.
The 1.9-inch display with a resolution of 320 x 170 pixels, which can display 8bit Colourn, as well as the USB-C socket and 2 buttons are located on the back.
Fastening can be done mechanically via the slots …
… or smart via the pre-integrated magnet.
Now we program the ESP32-S3.
