Adafruit Flora V3

The Adafruit Flora V3 is the go-to sewable microcontroller for wearable electronics — a 45mm round, Arduino-compatible board with 14 sewing tap pads designed to be stitched directly into garments. All components are flush to the PCB so they won't snag delicate fabrics.

Flora can drive 50 NeoPixels directly from its onboard supply, or up to 500 with external 5V power. USB HID support means it can act as a keyboard or mouse — no extra hardware needed.

Key Features

• 14 sewing tap pads — data buses interleaved with power/ground for clean conductive thread routing
• Drives 50 NeoPixels onboard, 500 with external 5V
• USB HID — keyboard/mouse emulation, no drivers needed
• Onboard RGB NeoPixel + 4 indicator LEDs
• JST battery connector (3.5–16V DC) — LiIon, LiPoly, LiFe, alkaline, NiMh/NiCad
• Onboard power switch (2A FET) + 3.3V 250mA regulator
• Reverse polarity protection — beginner-safe
• Arduino IDE compatible (1.6.4+)
• Made in NYC by Adafruit
