This board breaks out the VBUS, GND, D-, D+ and ID pins of a USB Mini-B connector. The VBUS and GND pins can be used to power your project from USB, while the D- and D+ pins give you access to the USB differential data signals. Each of these pins, along with the ID pin, are broken out into a 1×5 row of 0.1"-spaced pins on the board. The included 1×5 [straight male header](https://core-electronics.com.au/0-100-2-54-mm-breakaway-male-header-1x40-pin-straight.html) can be soldered to these pins to allow the board to be used with perfboards, [solderless breadboards](https://core-electronics.com.au/prototyping/breadboards.html), and 0.1" connectors.

This tiny unit measures only 0.52" × 0.85" (0.55" × 0.85" including its USB Mini-B connector) and has four 0.086" diameter mounting holes for #2 or M2 [screws](https://core-electronics.com.au/hardware/screws-nuts.html).

Pololu also carry a [USB Micro-B connector breakout board](https://core-electronics.com.au/usb-micro-b-connector-breakout-board-49997.html) and two different versions of USB 2.0 Type-C connector breakout boards ([usb07a](https://core-electronics.com.au/usb-2-0-type-c-connector-breakout-board-usb07a.html) and [usb07b](https://core-electronics.com.au/usb-2-0-type-c-connector-breakout-board-usb07b.html)).

Additionally, Pololu have two power muxes that double as USB Micro-B breakout boards: the [FPF1320 carrier](https://core-electronics.com.au/fpf1320-power-multiplexer-carrier-with-usb-micro-b-connector.html) and the [TPS2113A carrier](https://core-electronics.com.au/tps2113a-power-multiplexer-carrier-with-usb-micro-b-connector.html). These latter two power multiplexers make it easy to have a device that can be powered from both USB and an external supply.
