Contifan 3D Printer Kit MKS GEN 1.4 Board 12864 LCD Limit Switch 4988 Stepper Driver

Features:
A4988 is suitable for driving stepper motor less than 8V-35V 2A.
The adjustable potentiometer can control the maximum current output, thus achieving higher step rate.
Automatic current attenuation mode detection / selection.
Overheating shutdown circuit, undervoltage lockout and cross current protection.
Short circuit protection and short circuit protection.

Descriptions:
The circuit board is made of high quality 4 laminate and specially designed for heat dissipation.
Using high quality MOSFET tube, heat dissipation is better.
12864 built-in encoder, can realize parameter adjustment and file selection printing.

Specifications:
Material: plastic and metal 
Size: 143*84*15mm

Laliva 3D Printer – DC 12V Soil Moisture Sensor Relay Control Module Automatic Watering of The Humidity Starting Switch

Product Details
12V soil moisture sensor controller module Lower humidity start automatic watering
Humidity is below the set humidity start means that when soil moisture is below the set humidity , the relay will automatically pull, start spraying , water pumps , etc. do humidifying action reaches the set humidity is automatically stopped.
Purpose:
Adjustable via potentiometer control soil moisture threshold , which can automatically vegetable garden , garden automatic watering , household pots of soil moisture control , electronic game , etc., with a power relay , can control high current devices , less than the set humidity automatically start relay , more than the set humidity automatically disconnected , and a delay function to resolve without delay the humidity critical state relay flickered question is a simple and practical soil moisture control system.
Product Descriptions:
1 using the company\’s high-quality soil to make the soil moisture sensor detection surface is nickel plated, has widened sensing area can improve conductivity, prevent rust easily contact with soil problems and prolong life .
(2) products can be controlled over a wide range of soil moisture , adjustable via potentiometer control the corresponding threshold , the humidity is below the set value, the relay starts , higher than the set value, the relay is switched off .
3 product with a delay function , delay 3-5 seconds , when the humidity in the critical condition is detected , the relay does not flicker , flicker occurs .
4 high-quality products using Songle relay can withstand the load of 1500W , meet the requirements of most people .
5 products with a power indicator and relay instructions .
Electrical parameters:
Supply voltage : 12VDC Input current : more than 100ma
Load : 250V 10A AC or DC 30V 10A (below a current of this range can be used)
Module for use:
1 soil moisture sensor for detection .
2 modul
