1. I don’t have a Type- C connector on my PC. Can I still connect and use this kit?
Yes. To evaluate PSoC 6 MCU features, any PC with USB 2.0 connectivity is sufficient. A Type-C
power adapter is required only to evaluate the CCG3 section of the kit.
2. How does CY8CKIT-062-WiFi-BT handle voltage connection when multiple power sources are
plugged in?
There are five options to power the baseboard: Type-C USB connector (J10), external DC supply
via VIN connector (J9/ J1), debug and trace header (J12, VTARG_IN), program and debug
header (J11), and LiPo battery header (J15). Type-C and VIN take priority over other supply
options. These inputs are ORed using a diode and the higher voltage between the two take pre-
cedence. Output of ORing diode is given to a buck-boost regulator (
U30
) that generates a con-
stant 5.2 V. This output is ORed with ETM supply (J12), which is typically 5 V. For most practical
applications, output from the 5.2-V regulator takes priority and the same is given as an input to
the voltage regulator (U10). LiPo battery voltage is used when all the above sources are absent.
Output of buck regulator (U30) is ORed with supply voltage from the program and debug header
(J11), and higher voltage takes precedence. See
for more details on voltage input and
output scenarios.
3. How can I access Smart I/O and other GPIOs connected to onboard peripherals?
The Smart I/O (Port 8 and Port 9.3) and GPIO connected to the onboard peripherals are multi-
plexed with PSoC 6 MCU I/O headers (
J2
and
J20
). By default, some of these I/Os are con-
nected to onboard peripherals using series resistors. These resistors can be changed to route
these I/Os to headers. See
for the list of resistors that needs to be
changed.
4. Why does the red LED (LED5) light up when switch
SW7
is set to SuperCap position?
This behavior is observed if SuperCap is charged below 1.5 V. The I/Os referring to this domain
will leak current, in this case P0[3]. The VBACKUP feature needs to be enabled in the device
before switching
SW7
to the SuperCap position. See the device TRM or datasheet for options to
enable SuperCap charging.
5. What are the selection switches on baseboard used for?
gives details on all two selection switches.
6. What is the jumper on board for?
The jumper J8 can be used to measure current of the PSoC 6 MCU without the need to desolder
any component from the board. An ammeter can be connected across this jumper to measure
the current consumed by the PSoC 6 MCU. Remove the jumper on J8, connect an ammeter
(positive terminal of ammeter to Pin 2), and power the kit though USB connector J10.
