APM (ArduPilotMega) is a flight control product launched by the DIY Drones community in 2007. It is the most mature open source hardware project today.
The most complete six-axis robot design drawings
The SABER board for smart devices is based on the i.MX 6SoloX processor and supports 4-core processing, low-power multimedia and graphics applications.
A Russian Github master has open sourced a DIY lidar project, from PCB to host computer software.
The project implementation uses RSL10 and external mechanical control structure to complete wireless control of traditional switches.
NXP's OM2385/SF001 development kit for SIGFOX applications, including OL2385 and Kinetis KL43 series MCUs for host applications
The project presented here is a bipolar stepper motor driver. It is based on the BD63731EFV chip, a low-power driver driven by a PWM signal. The project power supply voltage is 8~28V DC, and the rated output current is 3A. The input interface adopts CLK-IN drive mode, and the excitation mode corresponds to FULL STEP mode (2 types), HALF STEP mode (2 types), QUARTER STEP mode (2 types), 1/8 STEP mode, 1/16 STEP mode through the built-in DAC . In terms of current attenuation, the SLOW DECAY/FAST DECAY ratio can be set without any restrictions and all available modes can be controlled in the most suitable way. Additionally, the power supply can be driven by a single system, simplifying design.
NXP MEK provides a platform for evaluation and development of the i.MX 8X series of application processors based on Arm Cortex A35 + Cortex-M4F.
STMicroelectronics provides users with a reference design based on L3751, suitable for DC-DC converters with input voltage 36-72V DC, output voltage 12 VDC, and 10A.
16-bit 10 MSPS ADC AD7626 single-ended to differential high-speed drive circuit
It is composed of labview front panel and back panel controls.
The meiji-led-ring is a compact light source that can be mounted on the front of a Meiji microscope. The illuminator uses 24 LEDs along with some high frequency boost drivers to avoid flickering when shooting. The device is powered by the USB-C port. A small ATSAML10 microcontroller is used to control the brightness of the LED driver. The user controls a series of touch sensors from the edge of the PCB.
Bluetooth ® Low Energy-NFC-v2.0 is an NFC expansion board for QN9020DK and an extensible QN9020 application development platform. This NFC expansion board is based on CLRC663+, a high-performance multi-protocol NFC front-end.
An ultra-mini frequency probe designed by foreign expert David Johnson. This frequency probe can help you debug the circuit by displaying frequency and voltage. It can measure periodic waveforms from 1Hz to 5MHz with an accuracy of 0.3%. Of course, it can also be used as a voltmeter. Use it to tell you the current voltage value.
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.
This article briefly introduces the application example of brush drive technology based on MM32SPIN motor/power supply dedicated chip in "servo trajectory control".
