The MCK-RA8T1 evaluation kit by Renesas comprises several boards for easy testing of the RA8T1 series microcontrollers in brushless dc (BLDC) motor-control applications. The following items are included in the kit:

  • CPU board, based on the R7FA8T1AHECBD MCU
  • Communication board
  • Inverter board
  • BLDC motor
  • Cables, screws, and standoffs

When assembled, this kit enables designers to configure the motor-control system via a USB connection to a PC. It can control up to two BLDC motors by connecting two inverter boards to the main CPU board, which features two Pmod headers for connecting additional modules during development.

The complete assembly can be powered by a 12 V to 48 V dc supply via a dc jack or terminal block connection. Alternatively, it can be powered using a 5 V USB connection to the CPU board.

As well as the MOSFET-based motor control circuit, the inverter board features current detection circuits to measure the current in the 3-phase system. An over-current detection circuit is also present, but this does not protect the board or motor. Protection operations must be processed and controlled using the RA8T1 MCU on the CPU board.

The inverter board also features connectors for Hall sensor signal input and pins for encoder or inductive position sensor signal input. These can be used to support accurate motor positioning when developing an application.


The EVSPIN958 single brushed dc motor driver expansion board is an easy-to-use solution for testing the performance of the STSPIN958 5 A full-bridge driver from STMicroelectronics. It supports a voltage range from 5 V to 58 V with a phase current up to 5 A.


The EVSPIN32G4 and EVSPIN32G4NH are demonstration boards based on the STSPIN32G4 SiP and STL110N10F7 power MOSFETs. The boards support three- or single-shunt configurations, and can run both sensorless and sensored control algorithms.

The integrated operational amplifiers for current sensing, the drain-source voltage sensing at each power MOSFET, and comparators for over-current protection make this a fully integrated solution for motor control.

Thanks to the integrated voltage regulators, both the gate driver and control logic supplies can be generated from the motor supply without dedicated circuitry. The board is intended to drive three-phase brushless dc (BLDC) motors in applications such as power tools, e-Bikes, fans, and home appliances.

A connector enables the EVSPIN32G4 to be interfaced with expansion boards, such as MEMS sensors or Bluetooth® transceivers. The on-board ST-LINK/V2 programmer speeds up and simplifies the debugging of microcontroller firmware.


The XMC1400 series from Infineon enables design engineers to safely handle motor systems consuming up to hundreds of Watts. The debug interface is isolated from the XMC1400 microcontroller and the position detection interfaces to guarantee safe operation during software development. 

The kit includes a power board connector, a set of position interface circuits with Hall sensor and encoder connectors, a USIC interface, and the isolated on-board debug interface.

Together with a three-phase inverter, the board demonstrates the capabilities of the XMC1402 MCU. The board includes six LEDs, two for power indication, one user LED, one encoder-enabled indicator LED, and two debug LEDs, and a potentiometer.


The B-G473E-ZEST1S Discovery kit, a part of the STMicroelectronics motor-control development platform, supports the ZeST and HSO algorithms. 

The B-G473E-ZEST1S is a control board featuring a STM32G473QET6 microcontroller in a ZeST Discovery pack. It works with a power board such as the STEVAL-LVLP01, an optional adaptor board such as the B-ZEST-ADAPT1, and an accessories package such as the B-MOTOR-PMSMA1. 

The B-G473E-ZEST1S control board is connected to the power board or adaptor board through an embedded V2 motor-control connector. The board can also operate with the X-NUCLEO-IHM08M1, X-NUCLEO-IHM09M1, or X-NUCLEO-IHM16M1 motor-driver expansion boards via a Morpho motor-control connector. 

The board includes an integrated STLINK-V3EC in-circuit debugger and programmer.
