1. Atmel Low Voltage Motor Control Starter Kit
The Atmel® ATSAMD21BLDC24V-STK is a low voltage BLDC, PMSM motor control starter kit. The kit
contains a driver board hardware with half-bridge power MOSFET drivers, current and voltage sensing
circuit, Hall and Encoder interface, fault protection circuits, etc. The ATSAMD21MOTOR MCU card is
plugged into the driver board and has an on-board debugger. Supported by the Atmel studio integrated
development platform, the kit provides easy access to the features of ATSAMD21J18A MCU and explains
how to integrate the device in a custom motor control application. Pluggable MCU cards are available
from Atmel, supporting other SMART ARM® MCUs.
