This 20×4 LCD board is used with the RAMPS 1.4 3D printer controller. You simply connect the LCD to the RAMPS board. This control unit has a built in SD card reader, rotary encoder as well as a 20×4 LCD display.
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.
4mm to 6.35mm (1/4″) Shaft Coupler
These stainless steel shaft couplers allow you to couple two size shafts together. They can be used for connecting motor shafts to drive shafts, or two different-sized shafts. These shaft couplers have a length of 0.75 , a outer diameter of 0.42 , and couple 1/4 to 4mm shafts.
3W High Power LED – Cool White
The 3W High Power LEDs are even brighter than standard incandescent and halogen light bulbs. Not only are they bright, they also consume a fraction of power making them extremely energy efficient! This high power LED is mounted onto an aluminium heat sink. Simply connect the large + and – pads on the heat sink to activate the LED. This high power LED is rated for 3.8V 700mA.
Stainless Conductive Thread – 30ft.
This is 30 feet of conductive thread spun from stainless steel fiber and wound on a plastic bobbin. Use it to sew up all of your e-textile projects. This small bobbin is a great way to get into wearable electronics without the upfront cost of buying an entire spool of thread. 30 feet of thread is enough to get a simple design stitched onto your shirt, backpack or hat.
NoIR Camera Board for Raspberry Pi
This is a 5 megapixel NoIR camera specifically designed for the Raspberry Pi. It is compatible with all revision of the Pi. The camera uses the OV5647 sensor in a fixed-focus module ensuring quality captures.
4 Pin (M-F) Jumper Wire
This jumper wire has a length of 450mm (18 inches) and comes with one male and one female end. The spacing pitch for the header is 2.54mm. This kind of flexible jumper wire is perfect for breadboard use as it fits perfectly in the breadboard.
6 Pin Circular Connector Set – Panel Mount
This 6 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.
Monolithic Capacitor (2 Pack)
This pack of capacitor consists of 2 individual monolithic capacitors which are each rated for 50V at 10% efficiency.
nF to uF Conversion:
Note: Please select the capacitance value from the drop down menu.
FDS5672 Motor Driver- 9A
This discrete MOSFET H-bridge motor driver enables bidirectional control of one high-power DC brushed motor. The little 1.3 0.8-inch board supports a wide 5.5 to 50 V voltage range and is efficient enough to deliver a continuous 9 A without a heat sink.
1W LED – White
The 1W High Power LEDs are comparable in brightness with the standard incandescent and halogen light bulbs. Not only are they bright, they also consume a fraction of power making them extremely energy efficient! This LED is rated at 3.8V 350mA .
Flexiforce Pressure Sensor – 1lb
This is a piezeoresistive force sensor from Tekscan. The harder you press, the lower the sensor s resistance. Pressing lightly, the resistance changes from infinite to ~300k. The sensor itself is thin and flexible, but the resistance does not change while being flexed. Resistance changes only when pressure is applied to the round area at the end of the sensor. Used as a presence sensor (someone standing), weight sensor, pressure sensor (impact testing), etc.
