This brushed motor system uses an MSP430 microcontroller, a DRV8837 brushed DC motor driver, and a 12V brushed motor. This system is suitable for applications requiring speeds up to 10,300 RPM under no load conditions. The system measures 19 x 33 mm without motor, making it ideal for applications requiring a small footprint. The motor power supply voltage supports 1.8V to 11V, and the maximum current is 1.8A. There are various configuration options for easily controlling the rotation of the motor, changing the direction of rotation, and placing the system into a low-power state to reduce energy consumption when not in use. The motor drive platform incorporates protection against short circuit, breakdown, undervoltage and overheating.
This design is a digitally controlled two-phase interleaved 700W power factor correction converter with added power metering capabilities. The power factor correction converter's two 180° phase-shifted boost power stages use a C2000™ Piccolo™ microcontroller, which also monitors line and neutral voltage waveforms for power metering functions. This design is able to achieve 97% efficiency and 1.5% THD (full load) with a power factor greater than 0.98. This design is an excellent choice for offline applications and AC/DC power supplies by minimizing power losses in the power stage, mitigating the reliability impact of harmonic distortion, and providing near-peak power factors.
By interleaving Renesas' low power, high sample rate ADCs, it is possible to achieve a combination of ultra-high sample rate and very high dynamic range that is not available in today’s stand-alone ADCs. This reference design demonstrates the performance attainable by combining Renesas' ADC technology and SP Devices' interleaving algorithms. In this design, four ISLA112P50 12-bit, 500MSPS analog-to-digital converters are interleaved to sample at a rate of 2.0GSPS. At this sampling rate, the reference design provides over 6dB more SNR and 13dB better SFDR than the best alternative stand-alone ADC.
The biggest feature of this open source oscilloscope is its strong waveform rendering (afterglow/fluorescence) effect. At the beginning, the author used Raspberry Pi Module 3, which can render 22,000 frames per second. In the later stage, NVIDIA Jetson is used, which can render 130,000 frames. frame. ZYNQ's FPGA is responsible for triggering and data acquisition, and A9 is responsible for transmitting data to the Raspberry Pi. Then the Raspberry Pi does the display processing. The ADC uses 1Gsps HMCAD1511.

It is a very beautiful and convenient little board. But it has a small flaw, the ice40 FPGA it uses is very simple, and it's generally fun to see people doing exciting projects with 5k LUTs. Sometimes it's convenient to have some extra space available when experimenting.
Desktop CNC machines often use stepper motors, often because they do not require position feedback sensors, thus reducing system cost. But there are situations where a position feedback sensor is needed or necessary, and the power output of a stepper motor, especially at high speeds, becomes a bottleneck for those who want a better performing machine.
This reference design uses the boost converter TPS61021A to provide a high-efficiency LED driver circuit with dimming capabilities. The PWM dimming method can be used for one or two AA battery input applications, while the analog dimming method can be used for one AA battery input application. The PMP15037 enables dimming functionality by adding multiple resistors and a MOSFET to the circuit, making it a cost-effective and efficient solution for LED driver applications.
