The Seeeduino XIAO supports the USB Type-C interface which can supply power and download code. Some PINs have various functions, A1/D1 to A10/D10 Pins have PWM functions and Pin A0/D0 has a function of DAC which means you can get true analog signals not PWM signals when you define it as an analog pin, that’s why 14 GPIO PINs can realize more I/O PINs and interfaces. Despite being this small size, it has 14 GPIO PINs, which can be used for 11 analog PINs, 11 digital PINs, 1 I2C interface, 1 UART interface, and 1 SPI interface. Here is our first board: Smallest: Seeeduino XIAO - Arduino Microcontroller – SAMD21 Cortex M0+ with Free CourseĪpart from the strong CPU, Seeeduino XIAO is excellent in many other functions. Well, we have compiled a few of the best SAMD21 Arduino boards currently and have categorized them based on their individual strengths.
So now you know what the SAMD21 is and its capabilities, which SAMD21 Arduino boards should you use?

It is as has a set of 6 configurable serial interfaces that can be turned into either a UART, I2C master, I2C slave, SPI master or SPI slave.ĭue to this feature, it provides you with a lot of flexibility as the ports can be multiplexed which gives you a choice of which task each pin is assigned. This is one of the most unique features that make the SAMD so special. The SAMD21 also has an RTC that is powered separately by an on-board crystal while it still clocks the processor at 48MHz. Need precise time-keeping for your digital clock or PID loop? Even though the ATmega328 has an RTC on board, it is required for timekeeping. On the other hand, as a USB host, the ATSAMD21 can connect a mouse or keyboard or also save data to a USB flash drive. It is able configure itself as a USB communication device class where you can connect it with a computer where you can talk to it as a serial port. The ATSMAD21 is equipped with an integrated USB controller which can be used as either a USB device or host.Īs a USB device, it is able to emulate a keyboard, mouse or joystick,etc. The increased resolution means that every bit between represents 0.806mV when the processor is powered at 3.3V which equals a more sensitive voltage measurement. The SAMD21 features 14 ADC input pins with a 12-bit resolution compared to 10-bit on the ATmega328p. Not to mention it features 32KB SRAM where you do not have to worry about dynamic memory stack overflows anymore.įurthermore, with SAMD21 max CPU speed of 48MHz, operating speeds will not be a worry anymore. In addition, extra flash storage means you can store large, user-defined blocks of data as well into your microcontroller. The SAMD21 256KB of flash means you would not be limited to only 32KB of space where you have to fit all of your compiled sketch into. Restricted by storage limits on your Arduino UNO? Or feel that other microcontrollers operating speed are just too slow? Well the SAMD21 will solve all of your issues. Why use the SAMD21? Large Memory and Fast Operating Speed Not convinced? Here are more reasons you should use the SAMD21: Six serial communication modules (SERCOM) configurable as UART/USART, SPI or I 2C, three 16-bit timer/counters, 32-bit Real-Time Clock and calendar, 20 PWM channels, one 14-channel 12-bit ADC, one 10-bit DACĪs you can see this is a very powerful microcontroller compared to the older 8-bit/16MHz Arduino microcontrollers.
