Micro Maestro 6-channel USB servo controller

(fully assembled) labeled top view.

Note: This section applies to the Micro Maestro servo controller. Please see Section

1.b for Mini Maestro pinout and component information.

The Pololu Micro Maestro 6-channel servo controller can connect to a computer’s USB port via a

USB A to mini-B cable [https://www.pololu.com/product/130] (not included). The USB connection is used

to configure the servo controller. It can also be used to send commands to the servo controller, get

information about the servo controller’s current state, and send and receive TTL serial bytes on the

TX and RX lines.

The processor and the servos can have separate power

supplies.

Processor power must come either from USB or from

an external 5–16V power supply connected to the VIN

and GND inputs. It is safe to have an external power

supply connected at the same time that USB is

connected; in such cases the processor will be powered

from the external supply. Note that if the external supply

falls below 5 V, correct operation is not guaranteed, even

if USB is also connected.
