USB and serial

Separate passive USB leads, connector adapters, breakout boards, USB-UART bridges and USB-C development boards before treating one as a replacement for another.

Passive USB leads and adapters

USB-A / Micro-B / USB-C

Use these when the job is physical USB connection or power/data lead selection. Check data-line support before relying on programming or serial communication.

from $1.754 boardsIn stock

USB connector breakouts

Raw USB connector pins

Useful when you need the connector mechanically or electrically broken out. Not a serial converter, charger or protocol adapter by itself.

from $5.751 board

USB-UART serial bridges

USB to TTL UART

Use these for serial console, bootloader or microcontroller programming tasks where USB must become TX/RX serial. Check logic level, chip, driver, control pins, and whether you need a board-only bridge or a kit with cable and headers.

Can I swap these?

Pick the board you have - we'll show what we know about swapping it.

Known swap options (1)

General board checks (5)
  • Decide the job first: power lead, data lead, connector adapter, connector breakout, USB-UART serial bridge or development board.
  • Check connector type, plug gender and cable direction. USB-C, Micro-B and USB-A labels do not guarantee the same physical role.
  • For cables, confirm whether data lines are present if you need programming, file transfer or serial communication.
  • For USB-UART boards, check logic voltage, TX/RX pinout, driver chip, OS driver support and whether DTR/RTS/reset lines are needed.
  • For dev boards, compare the whole board: MCU, bootloader, Qwiic/STEMMA/Grove connector, pinout and power path, not just the USB connector.
