It can display 256 pixels, such as Chinese characters, by row and column scaimiiig. \u003cbr\u003eThe kit comes with a microcontroller with a pre-programmed program. The startup display mode is: All lights up -love symbol - 'You are great\" character advertisement.Then repeat the above display content. \u003cbr\u003eThe microcontroller program of this kit has been burned, and the effect can be achieved after welding. \u003cbr\u003eThe source program is not provided. Since the main component of the kit is LED, tlie circuit is relatively simple and can be assembled in one go. \u003cbr\u003e\u003cbr\u003eCircuit principle: The control core of the circuit is the microcontroller U1, which continuously transmits row scanning data to U2 and U3 through the written program, and transmits display data to U4 and U5, there by controlling the display screen to display the corresponding pattern regularly.\u003cbr\u003e\u003cbr\u003e\u003cb\u003e\u003cspan style=\"font-size: 18px;\"\u003eFeatures:\u003c\/span\u003e\u003c\/b\u003e\u003cbr\u003e1. Pre-programmed Microcontroller Included: The set comes with a microcontroller that has been pre-programmed to display predefined patterns such as full screen, heart-shaped, and text advertisements.\u003cbr\u003e2. 256 Pixel Display: Capable of rendering complex shapes and text through its matrix of 256 LEDs, providing clear and customizable visual output.\u003cbr\u003e3. Simple Configuration: Designed for easy assembly, with straightforward electrical components and no additional programming required after soldering.\u003cbr\u003e4. Row Scanning Technology: Ensures optimized LED performance, providing efficient and consistent light emission across the matrix.\u003cbr\u003e5. Compact Size: The compact board size (97mm x 85mm) makes it ideal for a variety of applications, from desktop setups to integrated larger designs.\u003cbr\u003e\u003cbr\u003e\u003cb\u003e\u003cspan style=\"font-size: 18px;\"\u003ePackage Includes:\u003c\/span\u003e\u003c\/b\u003e\u003cbr\u003e1x Fixed Capacitor\u003cbr\u003e6x Chip Capacitors\u003cbr\u003e256x Red LED\u003cbr\u003e16x Chip Resistors\u003cbr\u003e16x Chip Transistors\u003cbr\u003e1x STC15F104W SMD Chip\u003cbr\u003e4x 74HC595D SMD Chip\u003cbr\u003e12x Pin Headers\u003cbr\u003e1x PCB Board\u003c\/p\u003e\u003cp\u003e1x Power Cable\u003c\/p\u003e","brand":"LinkMejor","offers":[{"title":"Default Title","offer_id":49119935365345,"sku":"BG-2033759","price":9.99,"currency_code":"HKD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0853\/9317\/8849\/files\/2041e19d-6a16-47c9-a5dc-a2fc9b23b5e9.jpg?v=1789396363","url":"https:\/\/ontproduct.com\/products\/linkmejor-dot-matrix-advertising-screen-kit-256-led-5v-dc-pre-programmed-microcontroller-diy-electronics-row-scanning-pcb-board-for-customizable-signage-displays","provider":"IvySource","version":"1.0","type":"link"}
