Yes, this is a main board integrated with LED driver, here’s the origin of this project, we always wanna have a tiny controller for LED strip that can be wearable, since Xadow mainboard has limited ports and\u00a0lack the ability for big current, we developed one with external battery holder and Grove dock.<\/p>\n

\"Xadow_-_LED_Strip\"<\/p>\n

This LED Strip module features a AtMega168 controller, communication with the main board via I2C, we occurred some problems in the\u00a0synchronization and reset function with the main board, driven by the need for an integrated led controller, the recent design is what you see in the last guess&giveaway.<\/a><\/p>\n
