In this workshop you’ll build a digital notebook, a pocket-sized device for taking notes with a USB keyboard. We’re using affordable, widely available components: a Seeed XIAO ESP32-S3 microcontroller, a 1-inch OLED display, and a microSD card reader, arranged on a solderless breadboard. The ESP32-S3 connects to the display via the I2C (Inter-Integrated Circuit) protocol, and to the microSD card reader uses the SPI (Serial Peripheral Interface) protocol.

No soldering required! Cutting and stripping jumper wires requires a degree of manual dexterity.
