STEVAL-IDI001V1 is an evaluation board based on the STM32F4 Microcontroller and a wide range of ST sensors. With a small form factor (4 x 4 cm), it represents an integration of sensors and CPU for a "sensor hub like" application. The hardware is compatible with STM32Nucleo and X-NUCLEO expansion boards. The included adapter board is an expansion board that allows the interoperability between STEVAL-IDI001V1, STM32Nucleo and various X-NUCLEO expansions. Expansion boards can be connected either via Arduino or morpho connectors. The evaluation board comes with built-in data logging firmware. It allows streaming and storing of the selected sensor measurements via USB or via bluetooth low energy if an X-NUCLEO-IDB04A1 (or X-NUCLEO-IDB05A1) is plugged through the adapter board. The acquired data can be used to implement new advanced algorithms.

The STEVAL-IDP003V1 kit includes the STEVAL-IDP003V1D evaluation board based on the L6362A IO-Link device transceiver and the STM32L071CZ microcontroller for data processing, as well as the following sensor daughter boards: STEVAL-IDP003V1T hosting the STTS751 temperature sensor, STEVAL-IDP003V1V hosting the IIS2DH MEMS sensor, STEVAL-IDP003V1A hosting the IIS328DQ MEMS sensor and STEVAL-IDP003V1P hosting the VL6180X proximity sensor. The evaluation kit is equipped with an industrial M12 connector (required by the standard) for connection with a single master IC using a 20-meter cable. The wire is a normal three-pole wire: one for IO-Link data, one for the L+ line (positive supply voltage pole) and one for the L- line (negative supply voltage pole). The layout is designed to meet IEC61000-4-2/4 and EN60947 requirements for the industrial sector.

The STEVAL-IDS001V4M evaluation board is based on the SPSGRF-868 CE certified RF module with the SPIRIT1 low-power Sub 1GHz transceiver and embeds the STM32L151CBU6A ultra low-power ARM Cortex-M3 MCU. The SPSGRF-868 module integrates the BALF-SPI-01D3 match balun and a chip antenna, and operates in the 868 MHz ISM band. The STEVAL-IDS001V4M evaluation board features a USB connector for PC-GUI interaction and firmware updates, and an SWD connector for specific firmware development.

The STEVAL-IFP010V3 demonstration board is based on the VNI2140J, a monolithic device designed using ST’s VIPower technology for driving two independent resistive or inductive loads with one side connected to ground. Active current limitation prevents a drop in system power supply if the load is shorted. A built-in thermal shutdown protects the chip from overtemperature and short-circuit conditions. During an overload condition, the channel turns off and back on automatically in order to maintain the junction temperature between TTSD and TR. If this condition causes the case temperature to reach TCSD, the overloaded channel is turned off and will restart only when the case temperature has decreased down to TCR. If more than one channel is in overload, the TCSD restart will not be simultaneous in order to prevent high peak current from the supply. Non-overloaded channels continue to operate normally. The open-drain diagnostic outputs indicate overtemperature conditions and open load in the off-state.

The STEVAL-IFP017V3 is an evaluation board designed to analyze the features of L6362A, including fast demagnetization, reverse polarity, overload, overtemperature, ground and supply open wire protections. The highly robust design of the L6362A allows the STEVAL-IFP017V3 to meet IEC 61000-4-4 (burst), IEC 61000-4-2 (ESD) and EN60947-5-2/IEC 61000-4-5 (surge) without additional external components. The STEVAL-IFP017V3 offers dedicated input and output screw connectors to facilitate easy and flexible connections for user requirements. The on-board red and green LEDs signal the IC status. On the STEVAL-IFP017V3, the exposed pad of the L6362A is connected to an electrically floating copper area which acts as a heatsink.

The STEVAL-IFP020V1 demonstration board is based on the L6370Q, a single-channel high-side driver chip intended for driving resistive, inductive or capacitive loads in an industrial environment. It provides an embedded fast demagnetization feature for inductive load switch-off. The device evaluates load disconnection (during channel on-state), output short to VCCor GND, overtemperature, undervoltage of supply voltage, and provides feedback to a control unit. Integrating an extensive set of electrical protections makes the application safe and reliable for use in harsh conditions. The STEVAL-IFP020V1 demonstration board is an example of application design using the L6370Q. It is used to guide the designer in choosing external components for applications while providing an appropriate PCB design.

The STEVAL-IFP021V1 demonstration board is based on the STEF05 and STEF12 electronic fuses (E-Fuses). It is designed to help users evaluate the benefit of the complete protection offered by the E-Fuse family and to customize their own application. The E-Fuse family of hot-swap converters is designed to replace the mechanical fuses on low voltage power lines. The STEF05 and STEF12 are integrated electronic fuses optimized for monitoring output current and input voltage. Connected in series to the 5 V/12 V rails, they are capable of protecting the electronic circuitry on the output from overcurrent and overvoltage. The turn-on time is programmable by means of an external capacitor, allowing control of the inrush current at startup and during hot-swaps. When an overload condition occurs, the E-Fuse limits the output current to a predefined safe value. If the anomalous overload condition persists, it goes into an open state, disconnecting the load from the power supply. If a continuous short-circuit is present on the board, when power is re-applied the E-Fuse initially limits the output current to a safe value, and then again goes into an open state. Both devices are equipped with a thermal protection circuit. The intervention of the thermal protection is signaled to the board monitoring circuits through a signal on the enable/fault pin that can be connected to other parts belonging to the same family to cause a simultaneous shutdown during failure events. Unlike mechanical fuses, which must be physically replaced after a single event, E-Fuses do not degrade in their performance after short-circuit/thermal protection interventions and can be reset either by re-cycling the supply voltage or by using the enable pin.

The STEVAL-IFP023V1 product evaluation board allows designers to evaluate the performance of the CLT01-38S4 high-speed protected digital termination array in industrial environmental conditions. The board includes two CLT01-38S4 chips connected to an SPI bus in a daisy chain configuration. It offers a 16-bit digital input interface and indicates each sensor logic state with an LED.

The STEVAL-IFP028V1 evaluation board is designed to help you analyze the functionality of the IPS160H single high-side switch for SIL2 and SIL3 compliant systems. The board meets application requirements for galvanic isolation between the user interface and the power interface through optical isolation implemented with two optocouplers, OPTO1 and OPT2, for forward signals to the device and for diagnostic feedback signals, respectively, in compliance with IEC 61000-4-2, IEC61000-4-4, IEC 61000-4-5 requirements. The STEVAL-IFP028V1 can operate in the 8 to 60 V range, but operation of the red LED on the DIAG pin is only ensured above VCC= 12 V, and you must ensure that jumper J1 is open for supply voltages above 40 V to avoid permanent damage to the SMCJ40CA transient-voltage-suppression (TVS) diode. The board also optimizes thermal performance through a careful layout which includes a dedicated copper area connected to the exposed pad of the PSSO12 package, which also serves to dissipate heat. You can use your PC to monitor the status of the output on the power side and receive fault information from the IPS160H DIAG pin by connecting the STEVAL-PCC009V2 interface board between your PC (via USB) and the STEVAL-IFP028V1 board (via 30-way flat cable), and then running the STSW-IPS16X GUI software, which is freely available on the ST website.
