Sensors And Module

This is a 1 Meter Long Waterproof, sealed and pre-wired digital temperature sensor probe based on DS18B20 sensor. It is very handy for when you need to measure something far away, or in wet conditions. Because they are digital, you don't get any signal degradation even over long distance.

These 1-wire digital temperature sensors are fairly precise (±0.5°C over much of the range) and can give up to 12 bits of precision from the onboard digital-to-analog converter. They work great with any microcontroller using a single digital pin, and you can even connect multiple ones to the same pin, each one has a unique 64-bit ID burned in at the factory to differentiate them. Usable with 3.0-5.0V systems.

The only downside is they use the Dallas 1-Wire protocol, which is somewhat complex, and requires a bunch of code to parse out the communication. When using with microcontroller put a 4.7k resistor to sensing pin, which is required as a pullup from the DATA to VCC line.

USR-K5 is a cost-effective TTL UART to Ethernet module with tiny size that can realize the bi-directional transmission between UART and Ethernet. It is used for data transmission between TCP/UDP packets and the UART interface.

USR-K5 is integrated with TCP/IP protocol stack, users can use it easily to complete the networking function of embedded devices, save manpower, material resources, and development cycle in the development process so that the product can be put into the market faster, enhance competitiveness.

The 3D printer 128×64 Smart LCD controller for ramps 1.4 contains an SD-Card reader, a rotary encoder and a 128×64 LCD display. You can easily connect it to your RAMPS board using the “smart adapter”.

After connecting this panel to your Ramps you don’t need your pc anymore, the Smart Controller supplies power for your SD card. Furthermore, all actions like calibration, axes movements can be done by just using the rotary encoder on the Smart Controller. Print your 3D designs without PC, just with a g-code design stored on the SD card.

Compares to the 2004 Smart LCD Controller With Adapter, this 128×64 screen can display much more information, which would help for you run the 3D printer without a computer.

We have provided the Arduino Code to Start smart LCD with RAMPS. You have to open the “Arduino code pdf “(Which is Provided below the ATTACHMENTS tab )  and go to “Configuration.h” and change as

Change “#define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER” (just remove the // at the beginning)

Upload the code, power off the Arduino, connect the panel, reapply power, and everything should work.

1. Large screen display 128×64 LCD (3.2″)
2. SD card slot at the back, able to directly select a file and print
3. The product comes encoder parameter adjustment can be achieved, and the file selection print
4. Plug & play on the RAMPS, but need to modify the firmware to support.
