GENERAL DESCRIPTION
This user guide describes the operation of the EVAL-ADPD6000Z
demonstration kit, which is an evaluation module for the
ADPD6000.
The ADPD6000 is a fully integrated analog front end (AFE) for
wearable vital signal monitoring (VSM) devices. The key functions
of the ADPD6000 include photoplethysmography (PPG), electrocar-
diography (ECG), and body impedance analysis (BIA).
The demonstration kit includes both software and hardware. The
EVAL-ADPD6000Z can evaluate the AFE feature and verify the
system design based on the AFE. According to the requirements of
the application, the user can use a cable connection or Bluetooth
connection to establish communication between the PC and the
EVAL-ADPD6000Z.
This user guide also describes the example configuration of the
different functions of the ADPD6000.
For full details on the ADPD6000, see the ADPD6000 data sheet,
which must be consulted in conjunction with this user guide when
using the EVAL-ADPD6000Z.

PCB CONNECTION
Take the following steps to establish the printed circuit board (PCB)
connection:
1. Connect the battery to the connector on the EVAL-VSMUCZ
(see Figure 3. Ensure that the S1 switch is off.
Figure 3. Battery Connected to EVAL-VSMUCZ
2. Connect the EVAL-VSMUCZ to the EVAL-ADPD6000Z (see
Figure 4 and Figure 5). Ensure the EVAL-VSMUCZ and EVAL-
ADPD6000Z have the same number of pins, and that the pin
numbers match.
Figure 4. EVAL-VSMUCZ Connection
Figure 5. EVAL-ADPD6000 Connection
3. For ECG or BIA measurement, connect the EVAL-ADPD6000Z
to the electrodes on the electrode board as follows:
►For ECG measurement, connect P3 to Electrode 1, P4 to
Electrode 2, and P6 to Electrode 3. Leave Electrode 4
unconnected (see Figure 6).
►For BIA measurement, connect P3 to Electrode 1, P4 to
Electrode 2, P6 to Electrode 3, and P5 to Electrode 4 (see
Figure 7).
Note that the BIA connection can also be used for ECG meas-
urement.

After preparing the hardware and installing the software, the EVAL-
ADPD6000Z is ready to power on.
POWER ON–CABLE CONNECTION
Connect the USB to Type-C cable from the PC to J5 on the
EVAL-VSMUCZ to power on the EVAL-VSMUCZ automatically. The
two indicator lights on the EVAL-VSMUCZ (DS1 and DS4) turn on.
If the S1 switch labeled in Figure 13 is set to on, the battery is
charged by the PC. Figure 13 shows the cable connection.
Figure 13. Cable Connection
POWER ON–BLUETOOTH CONNECTION
Take the following steps to power on the system without the USB
cable:

to on. The standalone DS1 indicator LED labeled in Figure 13
turns on.
2. Press (for about two seconds) the S3 button on the EVAL-
VSMUCZ to power on the system. The two indicator lights on
the EVAL-VSMUCZ (DS1 and DS4) turn on.
