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.
ATSHA204 Authentication Breakout
The Atmel ATSHA204 is an optimized authentication chip that includes a 4.5Kb EEPROM. This array can be used for storage of keys, miscellaneous read/write, read-only, password or secret data, and consumption tracking. Access to the various sections of memory can be restricted in a variety of ways and then the configuration locked to prevent changes.
Micro Servo Motor (1.5kg*cm)
The FS90 micro servo motor has dimensions of 23.2mm 12.5mm 22 mm. The operating voltage for this motor ranges between 4.8 to 6V with a maximum rotation of roughly 120 degrees. This servo motor comes with the servo horns and related hardware components.
Stackable Header Set for Arduino
Stackable Header Set for Arduino
These headers are made to work with the Arduino Uno R3, Leonardo and new Arduino boards going forward. The total height of the headers are 25mm with the pins at 13mm. This kit includes 5 headers (2 8-pin, 1 10-pin, 1 6-pin and 1 6-pin (2×3) ISP), enough to connect a shield to an Arduino board.
Aluminum Enclosure – 120x95x35mm
These beefy aluminum enclosures may look rough, but they re built tough. This 2mm-thick, die-cast enclosure is rated IP54 against dust and splashing water. Because it s aluminum, it s easy to cut and drill so that you can add LCD screens, buttons and cable connections. If you want to pretty up your project, hit this with some fine-grit sand paper and buff it or just spray paint it! The lid mates nicely to the top of the enclosure and is secured with 10mm long M3 screws (included).
TIP137 – PNP Darlington Power Transistor (-100V -8A)
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.
HX711 Load Cell Amplifier
The HX711 Load Cell Amplifier is a 24-bit analog-to-digital convertor designed for weigh scale and industrial control applications to interface directly with a bridge sensor. The HX711 contains high integration, fast response, immunity, and other features.
