5V 10A Switching Power Supply
This is a high quality AC to DC switching power adapter which gives a clean regulated 5VDC output at up to 10A. These adapter works with both 110 and 240VAC input, allowing them to work in any country! The barrel plug attached to these wall adapters are center positive with 2.1mm diameter.
ESP8266 Grove WiFi Module
UART WiFi is a serial transceiver module featuring the ubiquitous ESP8266 IoT SoC. With integrated TCP/IP protocol stack, this module lets your microcontroller interact with WiFi networks with only a few lines of code. Each ESP8266 module comes pre-programmed with an AT command set firmware, meaning you can send simple text commands to control the device. The SoC features integrated WEP, WPA/WPA2, TKIP, AES, and WAPI engines, can act as an access point with DHCP, can join existing WiFi networks and has configurable MAC and IP addresses.
MAX31855 Type K Thermocouple Amplifier
Thermocouples are very sensitive, requiring a good amplifier with a cold-compensation reference. The MAX31855K does everything for you, and can be easily interfaced with any microcontroller, even one without an analog input. This breakout board has the chip itself, a 3.3V regulator with 10uF bypass capacitors and level shifting circuitry, all assembled and tested. Comes with a 2 pin terminal block (for connecting to the thermocouple) and pin header (to plug into any breadboard or perfboard).
MMA7260 & LISY300 – 6 DOF Atomic IMU
The 6DOF Atomic is a stripped-down IMU, designed to give good performance. The unit can run as a hard-wired UART interface (0-3.3V, 115200bps), or optionally with an XBee RF module, and is powered from a single LiPo (Lithium Polymer) battery. The processor is an Atmel ATMega328 running at 10MHz with 6 dedicated 10-bit ADC channels reading the sensors. Source code for the 6DOF Atomic is freely available and compiles with the free AVR GCC compiler.
Type K Thermocouple
Thermocouples are best used for measuring temperatures that can go above 100 Degree C. This is a bare wires bead-probe which can measure air or surface temperatures. Most inexpensive thermocouples have a vinyl covering which can melt at around 200 Degree C, this one uses a fiberglass braid so it can be used in high temperature measurements such as heaters and ovens. There’s a small piece of heat shrink on the end to keep the fiberglass from fraying. If you’re using at >250 Degree C temperatures, simply remove it with a small blade.
EC3 Connector Set
These connectors are made from high-temp nylon with gold-plated spring pins or sockets molded in. The shape of this generic EC3 prevents reverse polarity, and when plugged in the connection is super-solid. Perfect for applications up to 65A continuous draw. Sold in pairs of 1 male and 1 female connector.
Featured Products
Black Metal Knob – 14x22mm
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 knob has a height of 14mm and a diameter of 22mm.
TIP3055 – NPN Power Transistor (100V 15A)
Power Transistors are transistors which can handle a lot more power in compared to BJTs. Similar to BJTs, the current flow between the collector and the emitter of is controlled by the current flow through the base.
8 Pin Circular Connector Set – Panel Mount
This 8 pin circular connector set has both the plug and socket. These connectors are panel mount style connectors with a diameter of 15.6mm. These connectors are often used as power connectors as they are rated for up to 6A.
2WD Robot Platform
The robot platform comes with 2 gear motor with 2 encoder disks. You can add the optical encoder module to start tracking the rotation of the motors. The main acrylic platform has many mounting holes for you to attach different things to it!
ADXL345 Triple Axis Accelerometer ( 2g/ 4g/ 8g/ 16g)
This ADXL345 module is low power 3-axis accelerometer, it uses I2C & SPI communication protocol where user can adjust the sensitivity and bit resolution. The ADXL345 is well suited to measure the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. Its high resolution (4 mg/LSB) enables measurement of inclination changes less than 1.0 Degree .
1 Turn Linear (B) Trimmer Potentiometer
This general purpose 1 turn trimmer potentiometer is perfect for adding small and discrete variable reisstor to your project! The dimension of this trimmer potentiometer is 5x5mm.
Note: Please select the resistance value from the drop down menu.
2 Pin JS (F) Wire Assembly
This is a 2 pin JS wire assembly with female headers. JS wires are an excellent way to make attachable and detachable polarized connections. There is an attachment notch which ensures that the direction of the connection is correct.
SPDT Stainless Steel Latching Switch – White
This is a perfect choice if you are in need of a heavy duty push button! These metal push buttons are a very tough, small, panel-mount latching switch with an illuminated LED ring. It is a SPDT with 16mm threading and 1mm pitch. This button is perfect for basic On/Off functions. Overall length (including leads) is 1.5″ and has small solder lugs for connection. These latched buttons are rated up to 3A and 250VAC while the LED is rated for 5V.
GP2Y0A21YK0F IR Proximity Sensor (10 to 80cm)
The GP2Y0A21 Sharp distance sensor is a great way to add obstacle avoidance or motion sensing to your robot or any other project. With a detection range of 4 to 32 (10 cm to 80 cm) and an analog voltage indicating the distance, this sensor is very easy to use.
