Demo example

Hardware connection

Materials needed

• Pico-RGB-Matrix-P3-64x32 (this product)
• Raspberry Pi Pico (must be purchased separately, if not, it is recommended to buy a version with soldered headers, which is convenient for direct insertion and use)
• Micro USB cable (must be purchased separately)

Hardware connection steps

1. 把底板对准红框处的槽位，接到RGB LED Matrix上
2. 取出配套的转接线，用钳子剪出需要用到的部分转接线（约10cm）
3. 把做好的转接线，一端连接到RGB LED Matrix，另一端固定到底板上
4. 背面安装上亚克力板和磁吸螺钉
5. 可选操作：如果觉得 RGB LED Matrix 比较炫眼或颗粒感较强，可以在屏上面贴上一层黑色亚克力盖板
