Guided Tour

Let’s have a quick look at the boards and what’s on them. Both boards have the same components except the USB connectors.

• USB A / USB Type-C Connector - Two options to choose from, use the one that works best for you! USB is used for both data and power. The Type-C connector supports only USB 2.0 signals and is hardwired to be a Sink only.
• Reset Button - Allows you to reset the board quickly and if you double press it, the board boots into the bootloader.
• 4MB Flash Storage - All 4MB of the storage are available to you, you can store your CircuitPython files as well as logs, images and more! When connected to a PC, the flash storage shows up as a disk drive.
• ATSAMD21 Microcontroller - Cortex-M0+ running at 48MHz, not the fastest thing around, but fast enough for prototyping and simple applications.
• 6 Flexible GPIOs - All 6 GPIOs can be used as analog inputs, PWM outputs or regular digital IOs. You can also configure them to be SPI, I2C and/or UART. See Pinout and GPIO Configurations for more details.
• 3.3V LDO - The LDO provides up to 250mA of current for you.
• RGB LED - Each color is user-controllable with a possibility to PWM the colors.
• Optional External Power - If you don’t want to use the USB to power the board, connect an external source (max 6V) to the VIN pin and you’re ready to go!
• Mount holes (Type-C only) - We used the extra space to provide you with two mounting holes in case you want to make sure your Serpente stays in place.
