Safety and regulatory compliance
information
Regulatory compliance information
Contains transmitter module FCC ID: VPYLB1DX and IC: 772C-LB1DX
This kit is intended to use for ENGINEERING DEVELOPMENT, DEMONSTRATION, OR
EVALUATION PURPOSES ONLY and is not considered by Cypress Semiconductor to be a finished
end-product fit for general consumer use. It generates, uses, and can radiate radio-frequency
energy and has not been tested for compliance with the limits of computing devices pursuant to part
15 of FCC or ICES-003 rules, which are designed to provide reasonable protection against radio-
frequency interference. Operation of the equipment may cause interference with radio
communications, in which case users at their own expense will be required to take whatever
measures may be required to correct this interference.
The kit contains Type 1DX (LBEE5KL1DX) certified module from Murata. Due to change in the
antenna pattern/type and gain used in this kit, Class II permissive changes are required to recertify
this kit. The radiated emission tests must be performed again to obtain a new FCC ID for this host
kit. Most conducted RF test results may still be reused. Customer also needs to take their product
through other FCC/ISED testing such as unintentional radiators (FCC sub part 15B) and any other
required regional product certifications including but not limited to EU directives. See FCC
Regulatory Certification Guide by Murata on information on pre-certified and reference certified
module concepts and information on what additional test are required for FCC certification.
Customer should consult a Telecommunication Certification Body (TCB) lab for guidance on other
requirements for the device certification.
For details on the Type 1DX module from Murata, see https://wireless.murata.com/type-1dx.html.
This kit contains electrostatic discharge (ESD)-sensitive devices.
Electrostatic charges readily accumulate on the human body and any
equipment, and can discharge without detection. Permanent damage
may occur on devices subjected to high-energy discharges. Proper
ESD precautions are recommended to avoid performance degradation
or loss of functionality. Store unused kits in the protective shipping
package.
End-of-Life/Product Recycling
The end-of life for this kit is five years from the date of manufacture
mentioned as a bar code on the back of the kit box. Contact your
nearest recycler for information on discarding the kit.

General safety instructions
ESD protection
ESD can damage boards and associated components. Cypress recommends that you perform
procedures only at an ESD workstation. If an ESD workstation is unavailable, use appropriate ESD
protection by wearing an anti-static wrist strap attached to a grounded metal object.
Handling boards
This kit is sensitive to ESD. Hold the board only by its edges. After removing the board from its box,
place it on a grounded, static-free surface. Use a conductive foam pad, if available. Do not slide the
board over any surface.

1. Introduction
Thank you for your interest in the CY8CKIT-062-WIFI-BT PSoC™ 6 Wi-Fi Bluetooth® pioneer kit.
This kit enables you to evaluate and develop your applications using the PSoC™ 6 MCU.
The PSoC™ 6 MCU is an ultra-low-power PSoC™ device specifically designed for wearables and
IoT products. It is a programmable embedded system-on-chip, integrating a 150-MHz Arm®
Cortex®-M4 as the primary application processor, a 100-MHz CM0+ that supports low-power
operations, up to 1 MB flash and 288 KB SRAM, CAPSENSE™ touch-sensing, and programmable
analog and digital peripherals that allow higher flexibility, in-field tuning of the design, and faster
time-to-market.
The PSoC™ 6 Wi-Fi Bluetooth® pioneer board offers compatibility with shields compatible with
Arduino. The board features a PSoC™ 6 MCU, a 512-Mb NOR flash, an on-board programmer/
debugger (KitProg3), a 2.4-GHz WLAN and Bluetooth® functionality module (CYW4343W), a five-
segment CAPSENSE™ slider, two CAPSENSE™ buttons, one CAPSENSE™ proximity sensing
header, an RGB LED, two user LEDs, USB host and device features, and one push button. The
board supports operating voltages from 1.8 V to 3.3 V for the PSoC™ 6 MCU.
The kit package includes a CY8CKIT-028-TFT display shield that contains a 2.4-inch TFT display, a
motion sensor, ambient light sensor, a 32-bit audio codec, and a PDM microphone.
You can use ModusToolbox™ software to develop and debug your PSoC™ 6 MCU projects.
ModusToolbox™ software is a set of tools that enable you to integrate Cypress devices into your
existing development methodology.
If you are new to PSoC™ 6 MCU and Eclipse IDE for ModusToolbox™ software, see the application
note AN228571 - Getting started with PSoC™ 6 MCU on ModusToolbox™ software to help you
familiarize with the PSoC™ 6 MCU and help you create your own design using the ModusToolbox™
software.

Introduction
1.3.2 CY8CKIT-028-TFT board details
Figure 1-4 shows the TFT display shield that has the following features:
■A 2.4-inch thin-film transistor (TFT) LCD module with 240 × 320 pixel resolution.
■A three-axis acceleration and three-axis gyroscopic motion sensor.
■A PDM microphone for voice input.
■A 32-bit stereo codec with microphone, headphone, and speaker amplifier capability.
■An audio jack with a provision of connecting both AHJ and OMTP headphones. The headset
standard can be set by an on-board switch.
■An ambient light sensor IC made of an NPN phototransistor.
■An LDO that converts 3.3 V to 1.8 V for the digital supply of the audio codec.
