Atmel SAML21 Xplained Pro development board. This board features the
ATSAML21J18A MCU.
The SAML21 Xplained Pro Starter Kit may be bundled with three modules:
1) I/O1 - An MMC/SD card slot, PWM LED control, ADC light sensor, USART
loopback, TWI AT30TSE758 Temperature sensor.
2) OLED1 - An OLED plus 3 additional switches and 3 additional LEDs
3) PROTO1 - A prototyping board with logic on board (other than power-related
logic).
