Sample inspected and tested per incoming shipment.This subreddit is dedicated to both amateur and professional engineers that want to build cool stuff at home, challenge themselves to learn new technologies, learn from each others' designs, and showcase their side projects.*/ int const RED_PIN = 6 // select a PWM pin for the red LED int const BLUE_PIN = 5 // select a PWM pin for the blue LED int const GREEN_PIN = 3 // select a PWM pin for the green LED int val = 0 //= // Initialization //= void setup ( ) BEFORE THEY ARE SHIPPED, THESE MODULES ARE: ALTW’s M8 and M12 SMT connectors are designed for waterproof protection in. They can be equipped on both sides and do not have via holes for the connection pins, making them cost-effective by reducing the PCB surface area. Connect the pins of the LED module to 3 PWM output pins using current limiting resistors of around 180 to 470 ohms The pins below can be changed to any 3 PWM capable pins if desired. Amphenol LTW (ALTW) M8 and M12 surface mount technology (SMT) connectors are two-piece connectors designed for PCBs. LED RGB SMD Module Test Program /* RGB LED module test Basic code cycling the colors of the RGB module. The LED is wired to pins 2, 3 and 4, but any 3 PWM capable pins can be used. Be sure to use current limiting resistors on the PWM outputs to avoid damage. The example code below uses PWM to show off some of the capability of the RGB LED. This allows the brightness of each of the R/G/B LEDs to be adjusted and therefore it is possible to color mix to get virtually any color you want from the LED. More commonly, RGB LEDs are driven using the PWM (analog) outputs of a MCU. This may be useful for a basic indicator where you want to be able to show several different states using different colors. Using it this way, you can get 7 colors consisting of Red, Green, Blue, Yellow (red and green both on), Purple (red and blue both on), Cyan (blue and green both on) or White (all 3 on). The minimal way to drive the LED is by using logic levels to drive the red/green/blue either individually or several together. With RGB LEDs, you can also add playing with color blending which allows you to create pretty much any colors of the rainbow. With regular LEDs, you can turn them on and off, blink them or pulse them rapidly to change the perceived brightness. LEDs tend to be fun to play with in general and RGB LEDs are the funnest of all. If you go by our connection diagram, you should be good to go. NOTE: On some modules, we have found the labeling on the R and G channels to be swapped. Connects to digital output/PWM pin on MCU. Connects to digital output/PWM pin on MCU. Available in 4 and 8 mm (0.157 and 0.315 inch) pin spacing (for higher rated voltage) Delivery in tape-and-reel packaging for full integration into SMT. Surface Mount Bluetooth v5.0, Thread, Zigbee Transceiver Module (2.4GHz, U. There is a 4-pin header on the assembly for making connections. SMD LED - RGB WS2812B (Strip of 50) In stock COM-16346. Higher values can be used but will reduce the brightness.ĭriving the outputs HIGH will light the LEDs. If the microcontroller you are using is limited to 20mA on the output pins, you can increase these values to around 180 ohms and 270 ohms respectively. Recommended resistor values are around 120 ohms for green and blue and 180 ohms for red. The cathode is connected to ground and the red, green and blue LED pins should be connected to digital or PWM output pins with series resistors to limit current to 30mA or less. The LED is a common cathode type which means all 3 of the LEDs have their cathodes tied together. ![]() The LED RGB SMD Module incorporates a red, green and blue LED in the same surface mount package which allows display of full RGB spectrum by mixing the colors.
