MGC3130 UNIT
The key element of the MGC3130 Unit is Microchip’s MGC3130 3D Tracking and
Gesture Controller. The layout print of the unit is shown in Figure 3-2.

The unit provides a 2 mm 7-pin board-to-board connector (socket) to connect the
electrode. The interface includes the following signals: GND, Rx4, Rx3, Tx, Rx2, Rx1,
and Rx0. Alternatively, the board-to-board connector can be replaced by a 1 mm
Flexible Printed Circuitry (FPC) connector which is prepared as a design option. The
five Rx channels of the MGC3130 (Rx0…Rx4) are connected to the receive electrodes
via 10 k
electrode. The interface includes the following signals: GND, Rx4, Rx3, Tx, Rx2, Rx1,
and Rx0. Alternatively, the board-to-board connector can be replaced by a 1 mm
Flexible Printed Circuitry (FPC) connector which is prepared as a design option. The
five Rx channels of the MGC3130 (Rx0…Rx4) are connected to the receive electrodes
via 10 k
resistors in order to suppress irradiated high-frequency signals (R11, R12,
R13, R14, and R15). The MGC3130 signal generator is connected via the Tx signal to
the transmit electrode.

The data connection to the Hillstar I

C to USB Bridge is realized by a 6-pin 2 mm
board-to-board connector (header). The interface includes the following signals: EIO0,
3.3V, GND, SDA0, SCL0, and MCLR. Alternatively, it is possible to use a 1 mm FPC
connector which can be assembled to the bottom side.

connector which can be assembled to the bottom side.
The MGC3130 unit acts as an I
2
C slave device. Table 3-1 shows the configuration of
the MGC3130 interface selection pins (IS1, IS2) which can be pulled to V
DD
or to GND
via resistors (R3, R4, R5, and R6) to select the I
2
C slave address. The I
2
C device
address 0x42 is set as default.
