Refund & Warranty
Thank you for your purchase. We hope you are satisfied with your product. However, if you are not completely satisfied with your purchase for any reason, ELEGOO provides a straightforward warranty that is processed in the most hassle-free way possible. Please refer to the warranty policy below, as warranty periods and conditions vary depending on the model and parts list.
1. Warranty Periods
1. Consumable Parts
Consumable parts are either excluded from warranty coverage or covered under a limited warranty period. For the purpose of this policy, "consumables" are defined as disposable items, components, or parts of the Product that are inherently designed to deteriorate or wear out during normal use of the Product.
While these items may not be covered by the standard warranty or may have a limited warranty period as specified in the table above, we will gladly replace any consumable that fails due to a manufacturing defect, provided the printer itself is still under warranty. ELEGOO reserves the exclusive right to determine eligibility for replacement, and such decisions shall be final.
2. Accessories or Parts Purchased Separately
Accessories or parts purchased separately enjoy the same quality assurance policy as the complete machine.
3. Warranty Periods
All periods stated on this page are calculated from the date the original order was received.
4. Warranty Forfeiture
This warranty does not cover the following cases:
A. Products not purchased from ELEGOO or authorized ELEGOO distributors with a valid receipt or invoice.
B. Products that are lost or stolen.
C. Products whose warranty period has expired.
D. Free products or products that have been refunded.
E. Products repaired by a third party or modified by an individual.
F. Damage caused by external factors or misuse of products (including but not limited to resin leakage, falls, improper operation), normal discoloration, wear and tear, or other non-quality-related issues.
G. LCD screens that can not provide an identifiable SN code.
5. Warranty in Other Regions
For consumers protected by local consumer laws in their country of purchase, ELEGOO's Limited Warranty benefits are provided in addition to all rights and remedies under such laws, including but not limited to those described above. If local regulations specify a warranty period longer than our stated policy, the longer period will apply, and we will fully comply with local requirements to support our customers.
Return & Refund Policy
Important Notes:
1. These clauses do not apply to pre-owned or refurbished items.
2. All return requests must be approved by our official customer support team and be sent to our designated address as instructed. Unapproved returns may be rejected or lost, and we are not liable for such cases. Please confirm with customer support before returning to ensure safe processing.
3. The original item must be shipped within 7 days (return label is valid for 7 days) after return/replacement approval. Failure to do so will void the request, and later contact may require re-troubleshooting.
4. Please retain the original packaging to ensure your product is protected during transit. Deviating from our packaging instructions may void the warranty and incur additional charges. For warranty claims, the original box and packing materials are required to avoid processing delays.
5. The returned product will be thoroughly inspected by ELEGOO upon receipt to determine if it meets the inspection criteria. If the returned product fails to meet these criteria, your refund request may be rejected or subject to a deduction fee at ELEGOO's sole discretion.

The Most Complete Starter Kit
Quantity and quality are both important here in ELEGOO UNO R3 starter kit. The most essential parts in this kit are UNO R3 controller board and expansion board, which is a perfect clone with an excellent product finish compatible with Arduino projects.
Besides, we offer over 60 kinds of components and sensors from small parts like LED diodes, resistors, and potentiometers to big parts like LCD1602, RFID modules,s and 830 tie-points breadboard, which meet your demands for your different projects whether it is simple or complex.
Sturdy quality is definitely the most important thing to ELEGOO even with so many components provided we never compromised on the quality. Instead, we keep improving our product quality in our factory and we produce the products by ourselves under high standards and strict quality control. Pins and wires on some of the parts like LCD16502 and motors have been pre-soldered which is very convenient and saves your time.


74HC595 is a Serial to Parallel Converter that has eight outputs (perfect) and three inputs that you use to feed data into it a bit at a time. This chip makes it a little slower to drive the LEDs (you can only change the LEDs about 500,000 times a second instead of 8,000,000 a second) but it's still really fast, way faster than humans can detect, so it's worth it!
74HC595 shift register is a type of chip that holds what can be thought of as eight memory locations, each of which can either be a 1 or a 0. To set each of these values on or off, we feed in the data using the 'Data' and 'Clock' pins of the chip.

LCD1602 module is a display that has an LED backlight and can display two rows with up to 16 characters on each row. You can see the rectangles for each character on the display and the pixels that make up each character. The display is just white on blue and is intended for showing text.
Lining up the display with the top of the breadboard helps to identify its pins without too much counting, especially if the breadboard has its rows numbered with row 1 as the top row of the board. Do not forget, the long yellow lead that links the slider of the pot to pin 3 of the display. The 'pot' is used to control the contrast of the display.

In this project, you will learn how to control a small DC motor using a UNO R3 and a L293D transistor, which is a very useful chip. It can actually control two motors independently. We are just using half the chip in this lesson, most of the pins on the right-hand side of the chip are for controlling a second motor.
L293D is a quadruple high-current half-H driver and designed to provide bidirectional drive currents of up to 1 A at voltages from 4.5 V to 36 V. The L293D is also designed to provide bidirectional drive currents of up to 600 mA at voltages from 4.5 V to 36 V and drive inductive loads such as relays, solenoids, DC, and bipolar stepping motors, as well as other high-current/high-voltage loads in positive-supply applications.
