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.
TS2016 – 2.8W AGC Stereo Audio Amplifier Module
This incredibly small stereo amplifier is surprisingly powerful. It is able to deliver 2 x 2.8W channels into 4 ohm impedance speakers (@ 10% THD) and it has a i2c control interface as well as an AGC (automatic gain control) system to keep your audio from clipping or distorting. If you don’t want to use I2C to control it, it does start up on with 6dB gain by default and the AGC set up for most music playing. We do suggest using it with a microcontroller to configure it, however, since its quite powerful. Settings are not stored in the chip, so you’ll need to adjust any gain & AGC amplification settings every time the amp is powered up.
18650 3.7V 2600mAh Lithium Ion Battery
This 18650 lithium ion battery has an output voltage of 3.7V with a battery capacity of 2600mA. These batteries comes with protection circuitry to keep the battery voltage from going too high or low. It is important to only use a constant voltage or constant current LiPoly charger to recharge them with a rate of 500mA or less.
