DC-DC boost converter
This 20W adjustable DC-DC boost converter with a digital display is based on the professional boost chip and supports 3~32V power input, 5~35V output, and an accuracy of ±0.05V. The switching frequency is 400KHz, the conversion efficiency can reach 94%, it has the functions of overheating prote...
Reset / Enable Controller - KA75330 3.3V Voltage Detector
A voltage detector is handy for projects where you want to make sure your microcontroller doesn't run at a low voltage. For example, say you have a Feather Huzzah running on a lipoly battery every few minutes. Eventually the battery runs down, and goes below 3.3V, so the voltage to the ESP8266...
TMC260 Stepper Motor Driver Shield For Arduino
INTRODUCTION This is a stepper motor driver introduced by DFRobot for those projects require powerful stepper motors, such as a pair of automatic curtains, an XY Plotter. This shield allows Arduino drive stepper motors (up to 2A per motor coil, 40V max). This stepper mo...
9g 270°Metal Servo with Analog Feedback (1.5kg)
A 9g micro servo with an extended 270° rotation range, metal gears, and built-in analog feedback (0–3.3V). The wider rotation range makes it suitable for applications requiring more travel than a standard 180° servo, while the analog feedback signal enables closed-loop position control via an MCU...
Standalone Momentary Capacitive Touch Sensor Breakout [AT42QT1010]
This breakout board is the simplest way to create a project with a single "momentary" capacitive touch sensor. No microcontroller is required here - just power with 1.8 to 5.5VDC and touch the pad to activate the sensor.When a capacitive load is detected (e.g. a person touches the sensor-pad area...
SparkFun USB-C Host Shield
The SparkFun USB-C Host Shield provides all the digital logic and analogue circuitry needed to add USB peripheral/host control to your Arduino. Interface with and control any USB 2.0 compatible device — thumb drives, digital cameras, Bluetooth dongles, game controllers, and more. This version up...
