shop/ arduino/ usb cable type b to type

USB 2.0 cable, Type-A male to Type-B male. Standard programming + power cable for any board with the printer-style USB-B socket — Arduino UNO R3/R4, Mega 2560, Mega ADK, Bluno Mega, and most legacy USB peripherals. 1 cable, 30 cm (1 ft).

specs

Connectors USB-A male ↔ USB-B male
USB version USB 2.0 (up to 480 Mbps)
Length 30 cm (1 ft)
Bus power Up to 500 mA at 5 V
Jacket PVC with aluminum foil shielding
Color Translucent blue
Drivers None — Windows, macOS, Linux plug-and-detect

common uses

  • Arduino sketch upload for UNO R3/R4, Mega 2560, Mega ADK
  • Serial debug at 9600–2,000,000 baud via the Arduino IDE Serial Monitor
  • Bench power for the board while developing (logic side only — not for motors)
  • Spare cable for school labs, classroom kits, and workshop bench setups
  • USB-B host connection for older printers, DAQ devices, and instruments

notes

USB 2.0 only — not rated for USB 3.0 SuperSpeed but mechanically compatible with USB 3.0 host ports (will fall back to 2.0 speeds). Bus power tops at 500 mA per USB spec; if you're running a motor shield, NeoPixel strip, or anything pulling more than 500 mA, supply the board through its barrel jack or Vin pin and use the USB cable for data only. Ships from Manila with same-day cutoff at 4 PM on weekdays.

Q: Works with Arduino UNO R4 WiFi?Yes. R4 keeps the standard USB-B socket, same as UNO R3. Same cable, same upload speeds.
Q: Will this power a motor shield?Only the Arduino logic side. Motors and heavy loads need their own supply via Vin or the barrel jack — USB caps at 500 mA.
Q: USB 3.0 compatible?Mechanically yes — the Type-A plug fits a USB 3.0 host port. Data speed stays at USB 2.0 (480 Mbps), which is more than enough for sketch upload and serial monitor.
Q: Drivers needed on Mac?None for the cable itself. Some Arduino clones with CH340/CH9102 chips need a USB-serial driver — the cable works fine, the board's USB chip is what may need a driver.
Q: What's your return policy?30-day window. If the cable is DOA, wrong connector, or shorted, email us with the order number and a photo — we replace.
