Compact microcontroller boards that fit into textiles or tiny enclosures give projects a programmable core without adding bulk, while USB‑based AVR programmers let firmware be loaded quickly from a PC. Simple two‑pin pigtail connectors provide reliable, solder‑free links to LED strips or other low‑signal lines, and slide switches offer straightforward on/off control for LEDs, buzzers or sensors. Integrated inertial‑measurement units with a standard I²C‑compatible interface deliver nine‑axis data for motion‑aware applications, and single‑output constant‑current LED drivers enable precise dimming of high‑power LEDs via PWM or analogue voltage. Low‑profile stepper drivers and 3.3 V Arduino‑compatible boards round out the range, giving developers flexible, dependable parts that slot into a wide variety of wearable, battery‑powered and automation projects.
