Adafruit Serpente - Tiny CircuitPython Prototyping Board - USB C Socket

The Serpente boards from Arturo182 are cost-effective development boards designed to seamlessly integrate with Adafruit’s CircuitPython. Equipped with a robust ATSAMD21 Cortex M0+ processor, these boards provide ample SPI flash storage for adaptable project needs.

Specifications include an ATSAMD21E18A 32-bit Cortex-M0+ running at 48MHz, sufficient for prototyping and basic applications. With 256KB flash and 32KB RAM, plus an additional 4MB for storing files and CircuitPython code, users gain flexibility and convenience as storage is recognized as a disk drive upon connection to a PC.

Featuring six highly customizable GPIOs, each configurable as analog inputs, PWM outputs, or standard digital IOs, there is versatility for various configurations like SPI, I2C, and UART. An efficient 250mA LDO provides 3.3V logic and power, ensuring reliable performance across applications.

A convenient reset button offers swift board resetting and accesses bootloader mode with a simple double press. Powered via USB or an external source, type-C connectors ensure robust connectivity. The user-controlled RGB LED allows creative PWM color control, and a breadboard-friendly design enhances physical integration.

Additional features include castellated edges for effortless modular design, a USB Type-C socket connector allowing you to bypass cables with an alternative plug type, mounting holes for the female Type-C board, and unassembled standard 0.1" male headers. Drawing inspiration from the Digispark boards, Serpente encapsulates a similar form factor and functionality, ideal for quick yet flexible prototyping endeavors.
