BOOSTXL-EDUMKII Educational BoosterPack™ Plug-in Module Mark II
2.1 Hardware Features
2.1.1 BoosterPack Plug-in Module Pinout
The Educational BoosterPack plug-in module MKII adheres to the 40-pin LaunchPad development kit and
BoosterPack plug-in module pinout standard (see Figure 3). A standard was created to aid compatibility
between LaunchPad development kits and BoosterPack plug-in modules across the TI ecosystem.
Figure 3. BoosterPack Plug-in Module Pinout
The 40-pin standard is compatible with the 20-pin standard that is used by other LaunchPad development
kits like the MSP-EXP430G2. This allows for 20-pin LaunchPad development kits to be used with 40-pin
BoosterPack plug-in modules with some limited functionality.
The BOOSTXL-EDUMKII supports BoosterPack plug-in module stacking with its male and female
BoosterPack plug-in module headers. See how many BoosterPack plug-in modules you can stack onto
your LaunchPad development kit to add more functionality like wireless and battery power.
More information about compatibility can also be found at http://www.ti.com/launchpad.
2.1.2 TI OPT3001 Light Sensor
The OPT3001 is a digital ambient light sensor (ALS) that measures the intensity of light as visible by the
human eye. Covering the sensor with your finger or shining a flashlight on it will change the output of the
OPT3001. The digital output is reported over an I2C- and SMBus-compatible, two-wire serial interface. The
reference designator for the OPT3001 is U2.
More information on the OPT3001 light sensor can be found at http://www.ti.com/product/opt3001.

2.1.3 TI TMP006 Temperature Sensor
The TMP006 is a digital infrared (IR) thermopile contactless temperature sensor that measures the
temperature of an object without being in direct contact. Placing your hand over the sensor increases the
sensor output. The digital output is reported over an I2C- and SMBus-compatible two-wire serial interface.
The reference designator for the TMP006 is U1.
More information on the TMP006 temperature sensor can be found at http://www.ti.com/product/tmp006.

2.1.4 Servo Motor Connector
The servo motor connector is a 3-pin header for the user to connect an external servo to be controlled.
Users can connect a servo and control it through the application code. The reference designator for the
servo motor connector is J8.

2.1.5 3-Axis Accelerometer
The Kionix KXTC9-2050 is a 3-axis analog accelerometer that measures g-forces. Moving the board along
the axes will change the analog signal generated by the accelerometer. The reference designator for the
accelerometer is U3.

2.1.6 RGB Multicolor LED
The Cree CLV1A-FKB RGB multicolor LED light output can make any color by mixing red, green, and
blue. Each color channel can be individually modified by pulse width modulation (PWM) to achieve the
desired color. The reference designator for the RGB LED is D1.

2.1.9 Microphone
The CUI CMA-4544PF-W electret microphone uses an OPA344 operational amplifier to boost the output
of the microphone. The human ear can hear frequencies between 0 and 20 kHz and the operating range
of the microphone is 20 Hz to 20 kHz. The reference designator for the microphone is MIC1.

2.1.10 2-Axis Joystick With Pushbutton
The ITEAD studio IM130330001 2-axis joystick with pushbutton is simply two potentiometers, one for each
axis. The select button is actuated when the joystick is pressed down. The analogRead statement reads
the voltage present on the joystick axis to provide the position of the joystick to the application (for
example, pushing the joystick to the left reads X = 0). The reference designator for the analog joystick is
JS1.

2.2 Power
The board was designed to be powered by the attached LaunchPad development kit, and requires both
3.3-V and 5-V power rails. Some 20-pin LaunchPad development kits like MSP-EXP430FR4133 may not
provide the necessary 5-V power, which will limit the functionality.

3.1.1 Source File Structure
The project is split into multiple files (see Table 14). This makes it easier to navigate and reuse parts of it
for other projects.

3.1.2 Operation
This demo uses the MSP432 built-in ADC14 to sample from the 3-axis acceleration data output of the
analog accelerometer on the Educational BoosterPack plug-in module MKII (see Figure 4). The measured
14-bit acceleration data are displayed on the BoosterPack plug-in module's colored 128x128 dot-matrix
LCD. Using MSP Graphics Library, the MSP432 MCU sends data to the LCD controller through SPI
communication to draw texts.
Figure 4. 3-Axis Analog Accelerometer
The demo makes use of the acceleration data by changing the LCD orientation when the BoosterPack
plug-in module is tilted in the corresponding direction.
