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.
Moisture Soil Sensor
This sensor uses the two probes to pass current through the soil, where it will measure the resistance to calculate the moisture level. More water makes the soil conduct electricity more easily (less resistance), while dry soil conducts electricity poorly (more resistance).
RFID/NFC Transparent Tag – 13.56MHz
This is a blank MiFare Classic ‘laundry’ tag – often used for laundry or identification but also found in other systems where a small proximity card is desired. This one is clear! The tag contains a NXP S50 chip and an antenna, and is passively powered by the reader/writer when placed a couple inches away.
Me Uno Shield
This module is a shield for the Arduino Uno. It can turn the Arduino pins into Makeblock RJ25 ports. You will be able to connect any Makeblock electronic modules to your Arduino Uno with this shield. This shield provides a stable power, so it can drive many servos and motors.
3 Pin Polarized Wire Assembly
The polarized connectors are also referred to as Molex connectors. This polarized wire set comes with a polarized socket and a 20cm polarized wire with open ended wire leads. The polarized socket has pitch spacing of 2.54mm.
8 Pin (M-M) Jumper Wire
This jumper wire has a length of 450mm (18 inches) and comes with both male ends. 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.
TIP120 – NPN Darlington Power Transistor (60V 5A)
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.
Analog Volt Meter (0 to 5VDC)
This analog panel meter measures DC voltage from 0-5 volts with 2.5% accuracy. It has a clear and easy to read scale and an adjustable dial. These come in handy for measuring the output of sensors with 5V ranges. The face of the meter is 45x45mm overall. The mounting hole should be 38mm. The overall depth of the meter is 35mm.
Pro Trinket – 3.3V 8MHz
Trinket’s got a big sister in town – the Pro Trinket 3V! Pro Trinket combines everything you love about Trinket with the familiarity of the core Arduino chip, the ATmega328. It’s like an Arduino Pro Mini with more pins and USB tossed in. Trinket’s a year old now, and while its been great to see tons of tiny projects, sometimes you just need more pins, more FLASH, and more RAM. That’s why we designed Pro Trinket, with 18 GPIO, 2 extra analog inputs, 28K of flash, and 2K of RAM.
LilyPad Arduino USB – ATmega32U4 Board
The LilyPad Simple just got a whole lot simpler. We ve updated the Simple board to create the LilyPad USB by replacing the classic ATMega328 with the new ATMega32U4. Not only does that mean that it s running a variation of the latest and greatest bootloader, but it also means no more FTDI Basic! The only extra piece of hardware you need to program the LilyPad USB is a micro-USB cable, since the new IC has built-in USB support. The LilyPad USB is also officially supported in the Arduino IDE as of version 1.0.2!
