Adafruit Serpente - Tiny CircuitPython Prototyping Board - USB C Plug

The Serpente boards from Arturo182 offer an economical platform for electronics enthusiasts, designed specifically for seamless integration with Adafruit’s CircuitPython. These open-source boards boast a robust ATSAMD21 Cortex M0+ processor capable of 48MHz, perfect for prototyping and straightforward applications.

Key features include 256KB flash and 32KB RAM, coupled with 4MB of SPI flash exclusively available for CircuitPython file storage. Simply connect to a PC, and watch the storage appear as a disk drive—ideal for storing CircuitPython files, logs, images, and more.

With 6 customizable GPIOs, the Serpente boards allow for flexibility; configure them as analog inputs, PWM outputs, digital IOs, or transform them to function with SPI, I2C, and UART. The 250mA LDO ensures ample current supply, while the board operates at 3.3V logic and power.

A reset button provides quick reboot capability, with a double press for bootloader access. Power the board via USB or an external source, with Type-C connectors designed exclusively as a USB 2.0 sink. A user-controlled RGB LED presents dynamic visual feedback, controllable via PWM.

Further underscoring usability, the breadboard-friendly design accommodates both GPIO and power, with mounting holes for added functionality. Castellated edges grant effortless adaptation of the Serpente boards as CircuitPython modules. Resembling Digispark boards, they provide similar form-factor and versatility as an effective prototyping tool.
