Arduino Board Includes a USB-C Port, LDR, Power Switch, and Many Other Features

Designed by Polia31, the Axiometa Spark is a Custom Arduino Board with all the most used features that are used in everyday projects.

Features of this custom Arduino board include a USB-C port, triple rows of pin headers for easy connections, an interrupt-supported user button, and additional I2C ports. Additionally, it has a light-dependent resistor (LDR), a dedicated power switch, multiple status LEDs, a battery connector, and an enhanced power regulator for stable 3.3V and 5V outputs, making it a highly versatile and user-friendly development tool.

This board improves on the classic Arduino by fixing common issues and adding new features. one example could be the USB port, the original Arduino UNO R3 has a USB-B cable which often doesn’t work or goes missing, and if it’s lost or brake it, you can’t use the device without soldering extra wires to the PCB. This new board solves that problem by adding a USB-C port onboard.

When working with multiple sensors, the single 5V and 3.3V outputs of the classic Arduino UNO can be limiting. This new board solves this by having three lines of I/O pins, making it easier to connect more sensors. It also has extra I2C headers, user buttons, and a power switch to easily turn the device on or off.
