USB connections

 THere are lots of different types of USB connectors and jacks.

In the synth world they are used for a wide variety of applications ... from simple power to data transfer

The jacks can be confusing

 

These were the first types

 

B is commonly called a printer USB cable.

A is still the most widely used type of jack. 

 

USB-B micro is commonly found on lots of synths made in the past 5 years 

though it seems to be fading out of popularity in favor of type C

 

 

 

 

 

 

 

 

 

 

 

 

 

 This Expert Sleepers FH-1 is a midi host

It uses a Type-A USB connector for MIDI

This is a 2HP midi module

It uses a USB-B micro socket

The Roland JUo6A boutique synth also uses a USB port: MicroB type for Audio, MIDI.

Older android mobile phones like my Samsung galaxy note 5 used this connector.

 

 THis has the advantage that you can plug your cable any orientation.

Most android mobile phones like my Samsung Galaxy 9 use this type of connector.

Many of these connectors supply power to your module.

It's handy to know what is what

The first two connectors (A + B) had just

four connections.

 

1 = +5V

2 = Data -

3 = Data +

4 = GND

The Mini & Micro cables added a 5th connector called

"ID". This helped distinguish cable ends.

 

 

 

 

So for the Mini/Micro USB A & B

 

1 = +5V

2 = Data -

3 = Data +

4 = ID

5 = GND 

This is the Teenage Enginering OP-z

It uses the Type-C connector

The OP-1 used type B-micro
