Museduino Shield

Distributed I/O

The Museduino distributes 5 different Arduino pins on ports A, B, C, or D labeled on the shield. A satellite (S) connected on either port allows access to the specified Arduino pins used for sensors/actuators.

3* D8D11~D5* D2~
5D6~* D9~* D3~D0
~ Denotes PWM          * Denotes PWM Switch

The shield and satellite boards have a labeled solder mask to assist with configuration. Changes to the labeling on our boards have simplified the pin chart.

PWM Select

The Museduino allows distributed PWM pins to switch between ports. For example, pin D9~ on port B can switch places with pin D8 on port A. Pin D3~ on Port D can also switch with Pin D2 on port C. This feature is useful when you need an extra PWM pin to be accessed from a Satellite board. board.

Power Jumpers

The Museduino shield and External Power board both include a jumper which allows for choice in power supply: 5V from the Arduino or an external source.

Satellite Boards


Named for its smorgasbord qualities, this satellite board allows for a wide range of sensor and actuator configurations on any port.

External Power board

The External Power board is designed for sensor and actuators that require their own external power supply (NeoPixels, DC Motors, etc).
