SparkFun RedBoard Turbo -SAMD21 Development Board (Qwiic)

Regular price $0.00 $31.94 Sale

Key Features:

  • An economical and easy to use development platform if you're needing more power than the classic RedBoard
  • ATSAMD21G18 32-bit/48MHz ARM Cortex-M0+
  • Analog-to-Digital and Digital-to-Analog Converters (ADC & DAC)
  • Qwiic Connector

The SparkFun RedBoard Turbo has been equipped with a USB interface for programming and power, a Qwiic connector, an RTC crystal, WS2812-based addressable RGB LED, 600mA 3.3V regulator, and a variety of other components. To power the RedBoard Turbo, just plug it into a USB port on your computer via the micro-B port or directly into the wall with the 5V tolerant barrel jack. The SparkFun RedBoard Turbo is also equipped with a LiPo Battery connector (for a single-cell 3.7-4.2V litium-polymer battery). The MCP73831's charge current is configured by a resistor value between 66kΩ and 2kΩ, to charge the battery at a rate between 15mA and 500mA, respectively. By default, the board is configured to charge the battery at around 250mA. The board layout meets the Arduino 1.0 footprint standard, including a separate SPI header and additional I2C header.

The RedBoard Turbo can even be flashed over the Mass Storage Class (MSC) just like a flash drive. With the UF2 bootloader, the RedBoard Turbo shows up on your computer as a USB storage device without having to install drivers! From the Arduino IDE, you’ll still need to select the correct port on your machine, but you can just as easily use another programming language such as CircuitPython or MakeCode.
