The STEVAL-DIGAFEV1 evaluation board allows the user to evaluate the performance of the TSC1641 16-bit, high precision current and power monitor with MIPI I3C/I2C interface. The board can measure voltage up to 60 V, a load current up to 10A delivered power, and temperature based on the dual channel power monitor. The current measurement can be high-side, low-side and bidirectional. Analog filters can be implemented on the board. Pull ups can be enabled/disabled for I2C/I3C communication to allow consumption optimization. The relevant address can be selected on the board with jumpers. The board is supplied ready-to-use in standalone mode, or it can be connected to a NUCLEO-L476RG or NUCLEO-H503RB board with an STM32 microcontroller, which enables further signal processing and PC communication. This product can be used with the STSW-DIGAFEV1GUI (only compatible with STM32H503RB).

The STEVAL-DPSG474 is a digital power supply control kit. It consists of a main board, based on the STM32G474RE microcontroller from the STM32G4 family, and an adapter board, which provides different communication interfaces and allows programming the microcontroller through a standard 20-pin JTAG connector. The STM32G474RE microcontroller includes the high-performance Arm®Cortex®M4 32-bit RISC core operating at up to 170 MHz frequency, a floating point unit (FPU), a full set of DSP (digital signal processing) instructions, and high-speed embedded memories (512 Kbytes of flash memory and 128 Kbytes of SRAM). The device embeds peripherals that allow the mathematical/arithmetic function acceleration (CORDIC for trigonometric functions and FMAC unit for filter functions). The MCU offers five fast 12-bit ADCs (5 Msps), seven ultra-fast comparators, six operational amplifiers, seven DAC channels (three external and four internal), a low-power RTC, 32-bit timers, three timers dedicated to motor control, seven general-purpose 16-bit timers, one 16-bit low-power timer, and the high-resolution timer (HRTIM) with 184 ps resolution, specifically designed to drive power conversion systems. The main board embeds a standard 64-pin DIN 41612 connector for connection with a power board. It provides all the PWM control signals, sensing networks, and protection features needed for a wide range of digital power supply applications. An external 5 V supply voltage can supply the board either through a dedicated connector or through the main connector. The adapter board features a configurable user communication (SMBus, CAN, or RS-232) with two DB9 connectors and the appropriate transceiver ICs, a standard STDC14 14-pin connector, which provides the SWD interface for debugging and USART communication for user interface (UI), and the standard JTAG connector for programming. The board also includes a reset button and a termination resistance between the CAN lines. You can easily connect the STEVAL-DPSG474 to another control board via opto-coupled serial communication and dedicated connectors.

The STEVAL-DRONE01 mini drone kit features the high performance STEVAL-FCU001V1 flight controller unit, as well as the motors, propellers, plastic frame and battery you need to assemble your own mini-drone. The flight controller unit runs the firmware (STSW-FCU001) to control the speed of each connected motor and to stabilize the drone. To achieve this, the STM32F4 microcontroller hosted on the board analyses data from the accelerometer and gyroscope sensors (LSM6DSL and iNEMO 6DoF inertial measurement unit) to provide highly accurate stability and control. The FCU board includes a Bluetooth Low Energy SPBTLE-RF module, so you can turn your smartphone running a dedicated App into a remote control unit.

The STEVAL-ESC001V1 reference design for electronic speed controllers (ESC) for drones fits entry-level commercial drone designs and drives any three-phase brushless (or PMSM) motor running off 6S LiPo battery packs, or any equivalent DC supply, up to 30 A peak current. The STEVAL-ESC001V1 lets you spin a motor and its propeller in minutes thanks to STM32 Motor Control Software Development Kit (MCSDK) with ST Motor profiler (X-CUBE-MCSDK). It implements a sensorless field oriented controlled (FOC) algorithm with 3-shunt current reading, speed control and full active braking. The reference design board can accept commands from a flight control unit through PWM signals; other communication bus interfaces like UART, CAN, and I²C are also available. The reference embeds a battery eliminator circuit working at 5 V, an NTC sensor for temperature measurement and circuitry for overcurrent/overvoltage protection (OCP/OVP). The compact form factor and current capability render this reference design suitable for electronic speed controllers on small and light unmanned aerial vehicles like professional drones. The X-CUBE-MCSDK software package lets you refine your electronic speed controller design. They act on the FOC parameters embedded in the STM32 and experiment with the ST motor profiler to retrieve rapidly the motor parameters. The ST sensorless FOC algorithm ensures longer flight times and optimal dynamic performance. The STEVAL-ESC001V1 is designed around the highly efficient, low RdsonSTripFET F7 power MOSFETs, the high-performance STM32F303CBT7 microcontroller with Arm®Cortex®-M4 core and the L6398 drivers.

The STEVAL-ESC002V1 board is a very compact and ready to use Electronic Speed Controller (ESC) reference design. The board can easily fit any small and light drone for racing or surveying purposes, and is also highly suitable for any three-phase BLDC application requiring a small form factor, minimal BoM, and high speed rotation performance. Together with the companion firmware package (STSW-ESC002V1), it represents a solution for sensorless voltage mode six-step driving. The heart of the board is the STSPIN32F0A advanced 3-phase brushless motor controller that embeds an STM32 Cortex®-M0®microcontroller, voltage regulators, signal conditioning circuitry and gate drivers in a small 7x7 mm² QFN package. The power stage is based on the 2.8 mΩ low resistance, high speed STL140N6F7 MOSFETs, designed with STripFET™ F7 technology and able to deliver up to 20 A of continuous current.
