3.75MM 8*8 dot matrix red highlight dot matrix module 1588BS
ขนาดหลอด : 3.75mm ขนาดโมดูล : 38x38mm ประเภท : Common Cathode (ลบร่วม) ระยะพิต : 2.54mm ขนาดความสูง panel : 10.30mm The main characteristics of commonly used small light-emitting diodes: ① The light-emitting diode is a one-way conducting device. Only current is allowed to flow from the positive pole to the negative pole. It only conducts and emits light when connected in the forward direction. Reverse access is blocked. Of course it doesn't glow either. This is similar to ordinary diodes. However, the tube voltage drop of light-emitting diodes is larger than that of ordinary diodes, about 2V. The power supply voltage must be greater than the tube voltage drop for light-emitting diodes to work. ②The brightness of the light-emitting diode is related to its operating current If. Generally, it lights up when If=1mA. As lf increases, the brightness continues to increase. But when lf≥5mA. The brightness increase is not significant. In addition, the maximum operating current of light-emitting diodes is generally 20 to 30mA. Exceeding this value will damage the light-emitting diodes. Therefore, the working current lF should be selected in the range of 5~20mA. In order to save power, lf=5mA is generally selected. ③The reverse breakdown voltage of light-emitting diodes is generally around 5V. During use, the light-emitting diode should not be subjected to a reverse voltage exceeding 5V. Otherwise, the LED will be damaged by breakdown.       |

Exchange or return policy
Every item comes with a 30-day warranty. However, there are certain conditions that apply:
-
The customer should not be responsible for any self-inflicted damage, such as incorrect power connections (for example, supplying 5V instead of the required 3.3V for a sensor).
-
The product must be in perfect condition, without any breakage or damage caused by electricity (e.g., short circuits leading to electrical fires).
-
The store does not accept product exchanges due to customer misunderstandings, such as purchasing the wrong size for their project or buying something without eventually using it. Customers can inquire about the product details and ensure compatibility before making a purchase by contacting us through our Line account @modulemore during business hours. Please note that there may be delays in response between 12:00 PM and 2:00 PM.
Return Policy: To initiate a product return, customers must provide the original receipt or a copy for quick verification. Returns can be sent to our store address by following these guidelines:
- Provide a detailed description of the damaged item(s).
- Mention any tests or experiments conducted by the customer.
Please note that the store reserves the right to make the final decision regarding product replacement or refund.
