Ultra-Small Size DC-DC 5v step-down buck converter 3a output 24V/12V to 5 V

Mini DC-DC 12-24V To 5V 3A Step Down Power Supply Module Voltage Buck Converter Adjustable Efficiency 97.5%.

Buck converters feature a controller with one or more integrated FETs and an external inductor, they offer a balance of flexibility and ease of use. Both non-synchronous converters (integrated high-side FET and external diode) and synchronous converters (integrated high-side and low-side FETs) simplify the design process by reducing external component count. At the same time, an external inductor allows you the flexibility to optimize your power supply for efficiency, size, or cost. No matter what your application is, we have a DC/DC buck converter and design tools to help you address your power supply design challenges.

Ultra-Small Size DC-DC Step Down Power Supply Module 3A Adjustable

This DC/DC step-down voltage converter is based on MP2303, it converts input voltage between 4.5V and 28V into a smaller voltage between 0.8V and 8V, capable of driving a 3A load with excellent line and load regulation.

Note: Input must be >1.5V higher than output! The chip will get to high temperature protection mode when it work at a high-power conversion, without any cooling, it is able to output 3A current at 5V. But at higher output voltage, the current output capacity is lower than 3A, approx 2A.

Ultrasonic Range Finder - LV-MaxSonar-EZ1-SEN-00639

This is the fantastically easy to use sensor from Maxbotix. We are extremely pleased with the size, quality, and ease of use of this little range finder. The serial interface is a bit odd (it's RS232 instead of standard TTL), but the PWM and Analog interfaces will allow any micro to listen easily enough. The sensor provides very accurate readings of 0 to 255 inches (0 to 6.45m) in 1 inch increments with little or no dead zone!

Water Coffee Flow Sensor Switch 0.3-6L/min YF-S401 white G1/4

 

Water flow sensor consists of a plastic valve body, a water rotor, and a hall-effect sensor. When water flows through the rotor, rotor rolls. Its speed changes with different rate of flow. The hall-effect sensor outputs the corresponding pulse signal. This one is suitable to detect flow in water dispenser or coffee machine.

  • Compact, Easy to Install
  • High Sealing Performance
  • High Quality Hall Effect Sensor
  • RoHS Compliant

Wearable solder Time II Spikenzielabs

The Solder : Time II is the latest version of our Solder : Time watch kit. This new version is even more hackable than ever. The on board microcontroller in this model is the very popular ATmega328P used in many of the current versions of Arduino. In fact, you can reprogram your watch using the same Arduino IDE software that you use for a regular Arduino. 

The Solder : Time II has a much more impressive display. Four 5x7 LED matrix modules gives you control of a 7x20 matrix for a total of 140 LEDs! 

The new LED matrix allows for an amazing amount of information to be displayed; time, date, month, words, scrolling messages, graphics, special characters ... the possibilities are endless. The ST2 also has a piezo buzzer for the alarm. You can also use it to add sounds to you custom programming or even games!

WiFi Module - ESP8266 (Genuine)

The ESP8266 WiFi Module is a self contained SOC with integrated TCP/IP protocol stack that can give any microcontroller access to your WiFi network. The ESP8266 is capable of either hosting an application or offloading all Wi-Fi networking functions from another application processor. Each ESP8266 module comes pre-programmed with an AT command set firmware, meaning, you can simply hook this up to your Arduino device and get about as much WiFi-ability as a WiFi Shield offers (and that's just out of the box)! The ESP8266 module is an extremely cost effective board with a huge, and ever growing, community.

This module has a powerful enough on-board processing and storage capability that allows it to be integrated with the sensors and other application specific devices through its GPIOs with minimal development up-front and minimal loading during runtime. Its high degree of on-chip integration allows for minimal external circuitry, including the front-end module, is designed to occupy minimal PCB area. The ESP8266 supports APSD for VoIP applications and Bluetooth co-existance interfaces, it contains a self-calibrated RF allowing it to work under all operating conditions, and requires no external RF parts.

XBee 3 Module - PCB Antenna (Genuine)

After years of popularity with the XBee Series 1 and XBee Series 2, we now have the XBee Series 3 which brings the best of both worlds. XBee 3 not only handles 802.15.4, and ZigBee, but also BLE protocols and you can now talk to the modules over UART or SPI as well. With a 200ft indoor range, or 4000ft outdoor/line-of-sight range, you can set up a mesh network to talk to or communicate with various devices around your house, work, or other area.

This module has the familiar XBee package while sporting a PCB Antenna. You also get a built in microcontroller so you can also configure and program the modules using MicroPython as well as Digi's XCTU software. With a HCS08 CPU running at up to 50.33MHz, 15x digital I/O pins, and 4x 10-bit ADC pins these modules can even hold their own as a microcontroller.
