The ATSAMR21-LED-DRIVER is a reference platform that uses the Atmel® | SMART ATSAMR21 microcontroller (MCU) to drive LEDs in a constant current DC-DC step-down topology. The ATSAMR21 is an IEEE 802.15.4 compliant SOC that incorporates an ARM® Cortex® M0+ based 32-bit MCU and a 2.4GHz RF transceiver.
The evaluation platform includes a SAMR21 Xplained Pro (ATSAMR21-XPRO) board with modified connectors, an add-on power component board, an LED load board with diffuser and Atmel AVR477 remote control.
