FreaksARM is a supper low-cost and miniature desktop robot Arm. It’s 4-axis robot arm and arduino-based. It is made up of laser cut wood parts and can be assembled in 1 hour. It is very suitable for children education and to help achieve the purpose of edutainment during familiarizing mechanical arm’s assembly structure and connection. It’s affordable,...
DC-DC sep-down adjustable power supply module 4.5V - 60V step down to 3-35V. The high quality LM2596 HV DC-DC sep-down adjustable power supply module 4.5V - 60V step down to 3-35V. Adopted imported LM2596HV-ADJ and Sanyo original patch electrolytic capacitors, it can convert the voltage and current stably.
This is a DC/DC step-down voltage regulator that converts input voltage between 3.2V and 40V into a smaller voltage between 1.25V and 35V, capable of driving a 3A load with excellent line and load regulation.
DC-DC step-up odule with precision potentiometer, it uses the XL6009E1 with the second generation of high-frequency switching technology as core chip, so that its performance is much higher than the first-generation technology LM2577.
Learn how to make double-sided, professional-quality PCBs from the ground up using Eagle – the powerful, flexible design software. In this step-by-step guide, electronics guru Simon Monk leads you through the process of designing a schematic, transforming it into a PCB layout, and submitting standard Gerber files to a manufacturing service to create your...
This low-cost (LC) Teensy Prop Shield is meant for making light and sound effects on small, handheld props and wearable costumes. This shield features a 2W audio amp, high-speed 5V buffers for driving APA102 LEDs, and an 8MB flash memory. This economical board is approximately the size of a Teensy, just slightly longer to allow space for mounting holes...
This 2xAA battery holder puts a nice finishing touch on your battery powered project. This holder features a removable, sliding cover, which is secured with a small phillips head screw. Another bonus is the ON/OFF switch which can be used to control power to your project.
10K thermistor with a negative temperature coefficient. Good choice for temp-sensing applications.
Knobs are a great way to finish off your project and make it easier to adjust the level of your death ray. This knob mates to a 0.25" shaft. The knob slides onto the potentiometer and holds tightly with a strong friction fit.
This is a row of 40 break away headers spaced 0.1" apart with long pins on both sides. This header is especially useful when you need to connect a PCB to a solderless breadboard. Each header can be broken apart to your preference to fit custom PCBs or general custom headers.
This is a very small light sensor. A photocell changes (also called a photodetector, photo resistor, CdS or photoconductive cell) resistance depending on the amount of light it is exposed to. These little sensors make great ambient light triggers (when light in the room turns on, do something).
Check out these big 10mm through-hole LEDs! The opaque epoxy package causes these LEDs to have a soft, diffuse glow.
These tiny little black anodized heatsinks are perfect for cooling off small surface-mount components such as the Allegro A4983 stepper driver.
This 2xAA battery holder puts a nice finishing touch on your battery powered project. This holder features a removable, sliding cover, which is secured with a small Phillips head screw. Another bonus is the ON/OFF switch which can be used to control power to your project.
