This LPC860-based motor control reference design includes PMSM flux direction control and BLDC motor commutation control. LPC860 utilizes flexible timers and ADC modules to provide a complete set of peripherals required for motor control, making it suitable for home appliance applications with three-phase motors or multiple DC brush motors.
The motor control reference design uses the LPCXpresso860-MAX evaluation kit and the FRDM motor control development kit, which includes the FRDM-MC-LVPMSM and FRDM-MC-BLDC driver boards to drive the motor. The controller uses a Flextimer (FTM) to generate a PWM signal and utilizes NXP's RECESL control algorithm library to trigger the ADC in an interrupt to run the motor control algorithm after the ADC sampling is completed.
This DIY LiPo super charger can charge a single LiPo battery and protect it from overvoltage, overload and short circuit. In addition, it can boost the battery voltage to 5 V or 12 V. The boosted output voltage is protected by an "eFuse" IC with a maximum output current of 1.52 A at 5 V and 0.76 A at 12 V. The charger part of the circuit requires a +5V power supply, which can be connected via USB-C, or simply solder two wires to pads on the PCB. Additionally, other connections can be soldered to pads on the PCB or use individual pin headers.
A programmable resistor is an electronic device whose resistance can be adjusted, usually through a digital signal. Programmable resistors come in the form of integrated circuits (often called digital potentiometers) as well as stand-alone devices/expansion cards. There are many different applications, each with its own set of requirements.
Range 1Ω - 999.999KΩ.
The PD150 is a compact 150MHz differential oscilloscope probe for engineers on a budget and advanced hobbyists. It has advanced features such as automatic DC offset voltage zeroing and low-frequency common-mode rejection tuning. It will also provide complete documentation in the spirit of old-school "anchor" test equipment, detailing its working principles in addition to typical instructions and specifications.
This open source has a complete host computer, slave computer and schematic diagram, as well as a detailed design paper.
The nRF52840 MDK USB Dongle is a small, low-cost development platform implemented by the nRF52840 multi-protocol SoC in a convenient USB Dongle form factor.
This is a simple USB sniffer based on the Raspberry Pi RP2040. It supports low speed and full speed modes. The firmware presents itself as a virtual COM port (VCP), so no additional software is required and it is compatible with all operating systems.
Commercial electronic loads are more expensive, especially high-power loads such as computer power supplies that must handle transient current spikes well above their nominal ratings (1800W spike for a 600W GPU) and should be tested under worst-case conditions to Ensure stability.
Flirting with jumper caps is a common practice on most boards, but not this board, which is designed to replace all those wires with an analog switch matrix. All one has to do is plug in the device and make a virtual connection on the accompanying GUI. There are also many built-in functions such as DAC and ADC, and the circuit can be switched under the prototype as needed. It also has some LEDs embedded in the breadboard area that light up and provide visual cues that they are connected to each other.
This reference design describes how to use TI's wireless M-Bus stack with the CC1310 and CC1350 wireless MCUs and integrate them into smart meter or data collector products. The software stack is compatible with the Open Metering System (OMS) v3.0.1 specification. EN13757-1 to EN13757-7 are European meter reading standards, including wired and wireless metering buses (M-Bus); these are very popular in ultra-low power metering and sub-metering applications. The design provides ready-to-use binary images for any wireless M-Bus S, T or C mode at 868 MHz, with unidirectional (instrumentation) or bidirectional configuration (instrumentation and datalogger). Multiple precompiled binary images are provided covering metering applications including but not limited to heat cost allocators (HCA), gas, water and heat meters, or electronic meters with external host MCUs.
