The Pro Micro is an Arduino compatible microcontroller development board based on the ATmega32U4 IC designed by Sparkfun Electronics. It is based around the Arduino Leonardo which means you no longer need an addition USB-Serial Interface to program your Arduino.
This pack includes: 2 pcs 6-pin lengthen female headers 2 pcs 8-pin lengthen female headers They all have 2.54mm spacing between pins and they are the perfect height for clearing the USB-B connector and great for stacking multiple shields.Their long legs also make it enough to connect a shield to an Arduino Main Board.
Chem-Wik® Rosin is especially designed for today’s heat sensitive electronic components. The lighter mass, pure copper braid construction allows for better thermal conductivity, even at low temperatures. Chem-Wik® Rosin responds as much as 50% faster than conventional desoldering braids. This design minimizes overheating and requires less “contact”...
Digital RGB ring is an intelligent light source consist s of WS2812B RGB LED with Integrated Driver Chip. The control circuit and RGB chip are integrated in a package of 5050 components.
This LED ring is a full-color that external control for each lamp beads. It with high brightness, can achieve effects of full color running water, chasing and scan.
