SparkFun Mini SAMD21 Microcontroller Board Products

Description

The SparkFun SAMD21 Mini microcontroller board breaks out the SAMD21 MCUMicrocontroller Unit on a board with a mini form factor (1.3in x 0.7in). The board includes a Micro-B USB connector for power and programming, reset button, and programmable LEDLight Emitting Diodes.

Processor

ATSAMD21E18 32-bit 48MHz ARMAdvanced Reduced Instruction Set Computer (RISC) Machines Cortex M0+

Memory

• 256KB Flash
• 32KB SRAMStatic Random Access Memory

I/OInput/Output

• 1x Micro-B USB connector (USB 2.0 Host or Device Full/Low speed)
• 22x Digital I/OInput/Output with PWMPulse-Width Modulation (3.3V Logic)
• 14x Analog Inputs 12-bit ADCAnalog-to-Digital Converter (ADC, A/D, or A-to-D) (0V to 3.3V range)
• 1x Analog Output 10-bit DACDigital-to-Analog Converter (DAC, D/A, or D-to-A) (0V to 3.3V range)
• Communication interfaces (3.3V Logic): 1x UARTUniversal Asynchronous Receiver-Transmitter, 1x I2CInter-Integrated Circuit. Also referred to as IIC or I²C., 1x SPISerial Peripheral Interface, and 1x I2SInter-IC Sound.
• 10 pins that break out the Cortex Debug Port SWDSerial Wire Debug interface (uses a 10-pin 0.05in pitch connector).

User Interface

• 1x Reset Button
• 1x Power Indicator LED
• 1x Pin #13 Status Blue LED
• 2x USB transmit and receive LED indicators

Power

The board can be powered by the Micro-B USB connector or by the VIN and GND pins. The input voltage range for VIN is between 3.5V and 6V. The on-board AP2112K 3.3V regulator is low-noise, low-dropout, and can supply up to 600mA, but has a maximum input voltage of 6V.

Board Size

33mm x 18mm (1.3in x 0.7in)
