These incredibly small surface-mount NeoPixel LEDs measure just 3.2 × 1.0 × 1.48mm, making them perfect for projects where space is at a premium. Each LED contains red, green, and blue elements with a built-in driver chip that provides ~12 mA constant current drive — no external resistors needed.
The slim round form factor supports multiple soldering orientations: flat against a PCB, reverse-mounted through a cutout, or right-angle. Like all NeoPixels, they can be daisy-chained with the output of one feeding the input of the next.
Key Features

- Constant Current Drive – ~12 mA for consistent colour regardless of voltage
- Chainable – Connect output to input for long chains
- Multiple Mount Options – Flat, reverse, or right-angle soldering
- 5V Operation – Simple single-supply power

Jargon buster
Plain-language definitions for the technical terms used above.
- Colour depth
- Colour depth describes how many different colours a display can show. A 65K-colour display can show about 65,000 colours, which is useful for icons, graphs, and simple full-colour interfaces but is less detailed than modern phone or computer screens.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- NeoPixel
- A type of addressable LED system where colour data is sent along a single digital data line from one LED or controller to the next. Compatibility matters because the timing and signal format must match for the lights or driver board to respond correctly.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
- PWM
- Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
- RGB
- Short for red, green and blue, the three primary colours of light that are mixed in varying amounts to make a wide range of colours. In electronics RGB can refer to an LED or pixel that blends these three colours, or to a colour signal or interface that carries separate red, green and blue channels.
