DRV2625 Haptics BoosterPack™ Plug-In Module
Table 1. Function Descriptions (continued)
Marker Section Name Function Description
5 Board pins
The 40 pins included in this board are used to connect the MSP-EXP430FR6989
LaunchPad with the DRV2625 BoosterPack. These pins include the functions of power
on/off the DRV2625, place it in shutdown mode (NRST pin) and provide an interrupt signal
(TRIG/INTZ) from it. The pins map is described in
Section 2.3 .
6
Actuator terminal and
test points
The LRA load must be connected to the terminal J5 for a proper usage. Since the OUT-
and OUT+ test points include a low pass filter, they can be used for measuring purposes.
7 LRA space The LRA load can be glued to this space for its evaluation.
2.3 Pinout
Only 10 pins are connected from the MSP-EXP430FR6989 LaunchPad to the BoosterPack. Pins 1, 3, 4,
8, 9, 10, 11, 20, 21 and 22, which are highlighted in green in table 2, allow the communication between
the two boards.
Pins 1 (3.3V), 20 (GND), 21 (5V) and 22 (GND) are used to power on the BoosterPack. The 3.3V from pin
1 are connected to the MSP430FR2512 power supply pin (DVCC). The 5V from pin 21 are connected to
the power supply pin of the DRV2625.
Pins 3 (UART_RX) and 4 (UART_TX) are connected to allow the serial communication from the MSP-
EXP430FR6989 to the MSP430FR2512.
Pin 8 (TRIG/INTZ) can be used either as interrupt signal which comes from the DRV2625. This pin alerts
the host processor (MSP-EXP430FR6989 in this case) of a critical condition such an over-current or over-
temperature event.
Pins 9 and 10 (SCL and SDA respectively) are the I2C communication pins. These pins allow the
connection between the LaunchPad and the BoosterPack. The MSP-EXP430FR6989 would work as the
master device, and the MSP430FR2512 and the DRV2625 as the slave devices.
Finally, the pin 11 (NRST) is the DRV2625 reset pin. This pin is connected directly to the BoosterPack and
LaunchPad microcontrollers so the user can reset the registers with either the BoosterPack or the
LaunchPad.
The rest of pins that are not highlighted in green can be connected to another board if required. The MSP-
EXP430FR6989 LaunchPad can be programmed to configure these pins according to the users’ needs.
