NK-NM1240L

The NK-NM1240L is an evaluation board (EVB) featuring an ARM Cortex-M0 MCU (NM1244) and an external 200V N/N-based gate driver (IR2101), along with external MOSFETs and variable resistors for controlling motor drive waveform and current phase. It supports the operation of three-phase brushless DC motors (BLDCMs) and permanent magnet synchronous motors (PMSMs), delivering a continuous drain current (IDSM) of 15A in 12V–48V DC rail or battery-powered applications.

The NK-NM1240L is designed for project evaluation, prototype development, and validation, allowing users to verify the functionality of motor application-based example code. For further development details, users can refer to the TRM and BSP of the NM1244 for software development.

The NK-NM1240L includes the Nuvoton Low Voltage Motor Development Module MOS (Nu-LVMDM-MOS) and the Nuvoton Motor Development Adapter (Nu-MDA-NM1244). The Nu-LVMDM-MOS serves as the power stage, while the Nu-MDA-NM1240 functions as the microcontroller stage. Note that the NK-NM1240L does not include a debugging tool, so users will need additional ICE debugging equipment, such as the Nu-Link-Me, for development.
