The JHU Robot Sensors and Actuators Education Board (JHURSAEB) is a microprocessor development board used in undergraduate robotics laboratory courses at the Department of Mechanical Engineering, Johns Hopkins University. This board utilizes the MaEvArM microcontroller platform developed by Prof. Jonathan Fiene at the Department of Mechanical Engineering and Applied Mechanics, University of Pennsylvania. The MaEvArM utilizes Amtel’s ATmega32U4 microcontroller. The USB interface built into this microcontroller allows programming of the device directly from a host computer via USB without the need for an external programmer, but the device can also be programmed and debugged through the SPI and JTAG interface.
The board wraps the M2 MaEvArM microcontroller with handy pinouts and a small breadboard for prototyping. The board can be powered by USB, 9V battery, or wall plug. External power can be separately supplied using banana jacks. Dedicated headers are provided for a serial Parallax LCD and JTAG debugging interface. Convenient for electronics labs, there are dedicated ground connections for use with oscilloscope probes.

Fall 2011 : 530.420 Robot Sensors and Actuators
This past fall, the JHURSAEB was used in conjunction with the 2011 530.420 Robot Sensors and Actuators Course offered at Johns Hopkins. The following labs were developed and used to introduce the JHURSAEB and the MaEvArM:
- Laboratory 3 Introduction to Microprocessors and the JHURSAEB/MaEvArM
- Laboratory 4 Serial Data Communication and Sonar Ranging with a Microprocessor
- Laboratory 5 Step Motors
- Laboratory 6 Analog to Digital and Digital to Analog Conversion
- Laboratory 8 Quadrature Decoding and SPI Serial Input
- Laboratory 9 Closed Loop Velocity Control
The JHURSAEB was also used by students to create independent design projects implementing sensors and actuators. Some student groups created videos of their projects, and they can be viewed on YouTube by searching for JHU ME 530.420 Fall 2011.
