1MORE BOARD OVERVIEW
The REV Robotics More Board is a passive expansion board designed for the roboRIO MXP (myRIO Expansion Port).
Every MXP signal is broken out to screw terminals and common 3-pin headers, effectively doubling the available Analog
and Digital IO/PWM ports on the roboRIO.

2FEATURE DESCRIPTION
The REV Robotics More Board includes a range of features designed to make expanding the roboRIO MXP port simple
and easy. This section describes each of these features in detail.
2.1 SCREW TERMINALS
Each MXP signal pin is broken out to a set of 3.5 mm screw terminals, labeled with their corresponding signal name. The
signals are grouped by major pin function in the following order:

Using a small slotted screw driver, loosen the screw at the top of the terminal you wish to use. Insert stripped wire into
the opening on the side of the terminal. While holding the wire in place, tighten the screw until the wire is held snug by
the terminal. Please see Table 2-2 for the recommended wire size.

2.2 HEADERS
Each MXP signal pin is broken out to sets of 0.1" pin-headers. Every Digital IO (DIO), Analog Input, and Analog Output is
brought out to 3-pin headers with the standard servo-style pinout: [GROUND][POWER][SIGNAL]. Serial interfaces shared
with DIO, I2C and SPI, are also brought out to single line headers. UART is only brought out in a single line header
because it is not shared with any DIO. Each signal is labeled next to its corresponding header group. Figure 2-1 shows
these pinouts.
Figure 2-1 Header Pinouts
2.2. 1 P W M C O NN E C T IO N S
PWM signals are shared with several DIO on the MXP. These signals, like all MXP signals, are passed through and
broken out without any intermediate active circuitry. For example, these PWM connections can be used to safely
connect motor controllers, keeping their PWM signals under control of the roboRIO.
CAUTION
Do not connect Servo Motors to the More Board.
The MXP and the More Board are not designed to provide power to Servo Motors. Even though 5.0V or 3.3V is provided
on the middle pin of the 3-pin headers, the required 6.0V is not brought out through the MXP and therefore not available
on the More Board. Servos must be connected to the roboRIO PWM ports.
2.2. 2 M X P P ASS - THRO U GH CO NNEC T O R
All MXP signals are routed to a female MXP header (J4) at the bottom edge of the More Board. Every signal is passed
through this connector so that additional MXP accessories can be connected with the REV Robotics MXP Extension
Cable (REV-11-1118).
2.3 POWER RAILS
The MXP can provide both 5.0V and 3.3V to connected expansion boards. Four separate rails exist on the More Board,
each with the ability to use the MXP 5.0V or 3.3V. These four rails are DIO VCC, I2C VCC, SPI VCC, and UART VCC. Each rail
has two methods of selecting the supplied voltage: a jumper shunt and a solder jumper.
Both the 5.0V and 3.3V rails can be disconnected with jumpers JP16 and JP14, respectively. This makes it possible to
connect an external power source to these rails.
2.3. 1 J U MPER SHUNTS
The 2-pin jumper shunts are installed on 3-pin headers and connect the middle pin to one of the outer pins. Move the
jumper to the side labeled with the desired voltage.
REV-11-1200-UM-02 Copyright © 2016 REV Robotics, LLC 7
2.3. 2 S O LDER JUMPERS
Next to each 3-pin power rail header is a set of two solder jumpers. These provide a more secure way to select the
voltage rail, but require the use of a soldering iron. To select a voltage rail, first remove the jumper shunt. Then, on the
solder jumper associated with the desired voltage label, flow a small quantity of solder onto the fork shaped pads so
that the connection is made between the prongs. See Figure 2-2 for a before and after example of selecting 5.0V for DIO
VCC using the solder jumper.
CAUTION
Take care not to short both solder jumpers. This can create a short between the 5.0V and 3.3V rails and damage the
roboRIO. It is also recommended that you remove the 2-pin jumper shunt when using the solder jumpers to prevent the
accidental shorting of the rails. See Figure 2-2 for examples of proper solder jumper usage.
Figure 2-2 Solder Jumpers
2.3. 3 ANAL O G S I GNALS
The 5.0V rail is directly connected to the analog headers because the roboRIO's Analog to Digital Converter (ADC)
measures between 0V and 5.0V. Analog ground (AGND) is broken out from the MXP and kept isolated from digital
ground (GND).

2.4 PROTOTYPING AREA
At the center of the More Board is a 16 x 16 0.1" grid prototyping area. The plated-through holes are arranged like a
standard breadboard with bus strips and terminal strips. Six bus strips run vertically with two on the left, two in the
center, and two on the right. These bus strips are electrically connected through the entire column (1 - 16). There are 16
5-pin terminal strips on each side of the center bus strips (A-E and F-J). The 5 pins are electrically connected in each
terminal strip. Figure 2-3 shows the prototyping area hole pattern.
Figure 2-3 Prototype Area Hole Pattern
By default, the bus strips are not connected to power or ground. 5.0V, 3.3V, and ground must be connected by soldering
a connection between the power pads (located at the bottom of the prototype area) and the bus strips.
2.5 MOUNTING HOLES
The More Board has 6 mounting hole locations throughout the board: 2 roboRIO mounting holes and 4 general mounting
holes. These mounting holes give flexibility in mounting the board, either mounted directly on the roboRIO or externally
using the REV Robotics MXP Extension Cable (REV-11-1118). Please see APPENDIX B DIMENSIONS for the mounting
hole placements. Table 2-3 shows the recommended mounting screw sizes.
