CYW920819M2EVB-01 evaluation kit user guide
Kit operation
5.
USB connector (J6):
J6 is a micro-B USB female connector for connecting the kit to PC using the provided
USB cable. It is used for programming and USB-UART communication.
6.
VPA_BT select jumper (J16):
This jumper is used to select the VPA_BT (power amplifier supply) power
source. This select header applies to evaluation boards that has an internal power amplifier and it is not
connected to CYW20819 in CYW920819M2EVB-01 evaluation board.
7.
KitProg3 (PSoC
™
5LP) programmer and debugger (CY8C5868LTI-LP039, U12):
The PSoC
™
5LP
(CY8C5868LTI-LP039) serving as KitProg3, is a multi-functional system, which includes a Serial Wire Debug
(SWD) programmer, debugger, USB-I2C bridge and USB-UART bridge. For more details, see the
8.
KitProg3 programming mode selection button (SW5):
This switch can be used to switch between various
modes of operation of KitProg3 (CMSIS-DAP BULK, CMSIS-DAP HID or DAPLink modes). This switch is not
used for CYW920819M2EVB-01 because the board supports only one mode.
9.
HCI-UART indication LED (D15):
This White LED indicates the status of HCI-UART.
10.
PUART indication LED (D16):
This Purple LED indicates the status of PUART.
11.
KitProg3 status indication LED (D5):
This Yellow LED indicates the status of KitProg3.This is not useful for
CYW920819M2EVB-01 because the board supports only one mode.
12.
SWD/GPIO switch (SW8):
This switch allows you to route the functionality of GPIO/SWD lines to either J4
Arduino-compatible header or the J13 debug header.
13.
Debug header (J13):
J13 is a 10-pin interface header that can be used to connect an external debugger via
SWD.
Note:
J13 should only be used to connect a debugger. If something else is connected to J13 to
communicate with KitProg3, a voltage mismatch can occur.
14.
Recovery button (SW1):
This button is used to put the device in recovery mode. To put the device in
recovery mode, press and hold the recovery button, press and release the reset button, and then release the
recovery button. You may need to put the device in recovery mode when the application download fails.
15.
Arduino-compatible header (J1):
The Arduino-compatible I/O header brings out pins from CYW20819 to
interface with Arduino shields.
16.
Reset button (SW2):
This button can be used to reset the device.
17.
Arduino-compatible header (J2):
The Arduino-compatible I/O header brings out pins from CYW20819 to
interface with Arduino shields.
18.
User button (SW3):
This button can be used to provide an input to the CYW20819 device. Note that the
button connects the CYW20819 pin to ground when pressed; therefore, the CYW20819 pin must be
configured as a digital input with resistive pull-up for detecting the button press.
19.
User LEDs (D1 and D2):
These onboard LEDs can be controlled by the CYW20819 device. The LEDs are active
LOW; therefore, these pins must be driven to ground to turn ON the LEDs.
20.
LED enable switch (SW4):
This switch is used to connect/disconnect the user-controlled LEDs from the
CYW20819 device.
21.
Carrier module (U1):
The carrier module has the CYW20819 SoC on it. A Bluetooth® antenna is etched on
the carrier module PCB. The carrier module is interface with the baseboard through M.2 interface.
22.
CYW20819 (U1. U1):
The Bluetooth® (BR/EDR- Basic Rate and Enhanced Data Rate) and Bluetooth® Low
Energy 5 qualified system-on-chip from Infineon is the heart of this evaluation kit.
23.
PCB antenna (A1):
The PCB antenna is the EM wave radiating part of the evaluation board, which is fed
from the BT_RFIO pad of CYW20819 followed by a band-pass filter and an antenna matching circuit.
24.
External antenna connector (U1.J3):
The external antenna connector is an RF connector fed from the
BT_RFIO pad of the CYW20819 device followed by a band pass filter. See
the product page for more details.
