20×4 Character LCD for RepRap Ramps 1.4
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.
MJE2955 – PNP Power Transistor (-60V -10A)
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.
Mini Digital Volt Meter (3.2 to 30VDC)
This mini digital panel meter measures DC voltage from 3.2-30V with 5% accuracy. You simply connect the red wire to the positive supply and the black wire to ground and it will automatically give you a digital reading of the supply voltage. The overall dimension of the meter is 31x14x12mm.
Straight Tweezers (ESD Safe)
This solid straight tweezer is made with stainless steel making it very durable. The tip on the tweezer is very fine allowing you to pick up very small parts with precision. This is a great tool to have when working with SMD components or anything with very small parts. There is also a EST-safe coating on the tweezer to prevent electro-static damage to sensitive components.
80 Teeth 8mm Anodized Gear
This 80 teeth gear has a center diameter of 8mm allowing you to connect to any 8mm shafts. The gear can be mounted with M4 hardwares using our4mm Mount Hub. This gear is made with anodized aluminum to minimize any rusting.
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.
5 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.
STMPE610 Resistive Touch Sensor
This breakout board features the STMPE610, which has both I2C and SPI interfaces available. There is also an interrupt pin that you can use to indicate when a touch has been detected to your microcontroller or microcomputer. We wrapped up the chip with a 3V voltage regulator and level shifting so it’s safe to use with 3V or 5V logic. Its a nicely designed chip, and has very stable precise readings. We found its also a lot faster than trying to do all the readings on an Arduino.
