BrightDots are small and wearable modules with one or more LEDs that need to be controlled by an Arduino compatible development board. The entire collection includes a series of diverse modules with addressable RGB LEDs that can be controlled individually. Use with Arduino compatible VMW101 ESP32 wearable development board and you can create something bright & wearable that's also smart. This set includes a medium Brightdot circle. Each PCB is super thin and includes gold plated contacts with 6 sewing holes of 1.22mm (0,04 inch). Backup lines ensure that one broken LED does not affect the others. Every LED is controlled by 3 wires (power, ground & data) and can be connected via these wires to the next LED, creating a big string of LEDs. You can solder these LEDs in electric circuits, or sew them into clothing, onto backpacks, onto shoes, …
