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.
Electret Microphone Module – Adjustable Gain
Add an ear to your project with this well-designed electret microphone amplifier. This fully assembled and tested board comes with a 20-20KHz electret microphone soldered on. For the amplification, we use the Maxim MAX4466, an op-amp specifically designed for this delicate task! The amplifier has excellent power supply noise rejection, so this amplifier sounds really good and isn’t nearly as noisy or scratchy as other mic amp breakouts we’ve tried!
Heaterizer XL-3000 Heat Gun
The Sparkfun Heaterizer XL-3000 heat gun is a handy tool that everyone should have. It s great for heat-shrink, melting things, and even very basic low temp rework. The size is great for a lot of different applications and it heats up pretty quickly.
MQ Gas Sensor Breakout Board
This carrier board is designed to work with any of the MQ-series gas sensors, simplifying the interface from 6 to 3 pins ground, power and analog voltage output that are broken out with a 0.1″ spacing, making the board compatible with 0.1″ headers and standard breadboards and perfboards. This board has two mounting holes and provides convenient pads for mounting the gas sensor s required sensitivity-setting resistor.
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.
Stackable Header Set for BeagleBone
Stack to the max with our Beagle Bone Proto Cape using these ingenious stacking headers. They’re just like 2×23 0.1″ spaced female headers but with a twist! The ‘legs’ are extra-long so you can solder it -through- a PCB and plug it into the Bone. You can stack as many as you’d like, for modular design. Neat, right
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.
3 Pin Low Profile Connector Set
The low profile header set is great for making your own PCB wire connections. This is a low profile header set, which includes a wire housing, pcb socket, as well as the crimpable pins. The pitch spacing for the socket is 2.54mm.
