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 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.
The EVL012LED is an LED driver board. The architecture is based on a two-stage approach: a front-end PFC pre-regulator and a downstream resonant half-bridge converter, using the new STNRG012 IC that integrates the controllers of both sections in a single device.
The main features of this design are high efficiency, low power consumption at no load without an auxiliary supply, good power factor with low harmonic content, and reduced component count.
The board also has a full set of protection features including output overload, short-circuit, and over-voltage, all of which can be easily defined as latched or auto-restart by changing a value in the non-volatile memory of the controller.
The STEVAL-ILD003V1 demonstration board implements a low-cost analog dimmer using the TS820-600FP, a sensitive-gate silicon-controlled rectifier (SCR) thyristor. The dimmer can drive typical low-power lamps such as compact fluorescent or dimmable LED lights.
Through-hole technology is used for the most important components, such as an LC filter, gate resistor, and turn-on delay capacitor, to allow for modification of the board.
The STEVAL-ILD003V1 eliminates flickering thanks to its continuous current applied through the sensitive SCR gate. This dimmer could easily replace a standard low-cost analog triac light dimmer using a diac-controlled circuit.
The STEVAL-ILD003V1 is for use in Europe at a mains voltage of 220 V. A 110 V version, the STEVAL-ILD003V2, is for use in North America.
Key features:
The STEVAL-MKI231KA demonstration board provides a hardware platform for evaluating the STHS34PF80, an infrared motion and presence-detection sensor from STMicroelectronics.
The demo board is connected through flat cable to a generic adapter board, the STEVAL-MKIGIBV5, to make it compatible with the STEVAL-MKI109V3 microcontroller board. An ad hoc plastic holder with a Fresnel lens (TMOS63-10) has been provided in the kit to enable the designer to verify the in-application performance of the device.
The STEVAL-MKIGIBV5 can be plugged into a standard DIL 24 socket. The kit supports the complete STHS34PF80 pin-out, and comes ready-to-use with the required decoupling capacitors on the power supply line.
This adapter is supported by the STEVAL-MKI109V3 motherboard, which includes a high performance 32-bit MCU functioning as a bridge between the sensor and a PC, on which it is possible to use the downloadable graphical user interface, or dedicated software routines for customized applications.
It is also possible to plug the board into an X-NUCLEO-IKS01A3, X-NUCLEO-IKS02A1 or X-NUCLEO-IKS4A1 board. The kit is supported by an X-CUBE-MEMS1 expansion software package for STM32 MCUs.
