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.
Half Size Breadboard FR4 Protoyping Board
This PCB has the basic layout of a half-sized breadboard. With its identical layout, you can transfer your prototype made on a breadboard onto this PCB with ease. It has 4 power rails, 10 columns, and 30 rows – with a total of 400 soldering points. All pins are spaced by a standard 0.1″. The two sets of five columns are separated by 2 columns with a distance of 0.4″ between the holes.
Love FLORA but want a bite-sized version Look no further, GEMMA is a tiny wearable platform board with a lot of might in a 1″ diameter package. Powered by a Attiny85 and programmable with an Arduino IDE over USB, you’ll be able to realize any wearable project!
12-36V Large Push Pull Solenoid
Solenoids are a great way to induce linear motion for pushing, pulling or controlling switches and levers. According to the datasheet this solenoid is rated for 36V but they work like a charm at 12V. We ve been controlling them with the Arduino Power Driver Shield, there s even some example code below. With a throw of 10mm these solenoids are great for all kinds of motion applications such as actuating door latches, automating percussion instruments or just poking people.
12V 10A Temperature Control Relay (-55 to 110 Degree C)
This is a temperature controlled DC relay, where the relay can be set to turn on/off when the temperature reach higher/lower than the desired base temperature. You can set the base temperature by pressing the onboard switches. There is also a LED indicator to show you when the temperature is higher/lower than base amount.
Arduino Pro Mini 328 – 5V/16MHz
This is a 5V Arduino running the 16MHz bootloader. Arduino Pro Mini does not come with connectors populated so that you can solder in any connector or wire with any orientation you need. The Arduino Pro series is meant for users that understand the limitations of system voltage (5V), lack of connectors, and USB off board.
72mm Mounting Plate
This mounting plate is made from 6061 aluminum with anodized surface. This 72mm Mounting Plate is perfect for building symmetrical mechanical structure such as 120 degree three-wheeled car, three axis helicopter, four axis helicopter. The center hole has a diameter of 8mm which can be used to attach 8mm shafts and bearings. There are also a total of 26 x 4mm holes as well as 6 x 3mm holes.
EM4001 USB RFID Reader – 125kHz
This RFID reader will allow users to hover the RFID card over the reader and obtain data to their computers. It will work on any windows based operating system. The cards supported are EM4001/4100 or its compatible RFID Cards that operate at 125KHz. This device will essentially read the first 10 digits of the RFID Card.
