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:

  • For 2-wire wall dimmers
  • Leading-edge control compatible with all lamp types commonly found on the market
  • Dimmable power range: 3 W to 350 W 
  • 60°C maximum ambient temperature 
  • Higher than 99% power efficiency at 350 W/230 V
  • Less than 0.5 W standby power losses

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.

The STM32C0116-DK Discovery kit from STMicroelectronics provides a convenient platform for exploring the features of the STM32C0 family of microcontrollers. The board includes an STM32C011F6 MCU in a 20-pin UFQFPN package, and an onboard ST-LINK/V2-1 to debug and program the MCU.

The STM32C0116-DK Discovery kit is operated by plugging it into a PC through a standard USB Type-A or USB Type-C®-to-Micro-B cable.

Key features of the board are:

  • User LED
  • Reset push-button
  • 5‑way joystick using a single ADC input pin
  • STM32 UFQFPN20-to-DIL20 module
  • Board connectors:
    • USB Micro-B
    • DIL20 socket
    • Dedicated LCD footprint
    • Grove (UART)
    • 2 x 10‑pin headers for MCU daughterboard
    • Extension connectors
  • Comprehensive free software libraries and examples available with the STM32Cube MCU package
  • Supports a wide choice of integrated development environments including IAR Embedded Workbench®, MDK-ARM, and STM32CubeIDE
