Hardware

There are several different kits that may be used in the exercises for this class.

To do exercises in all chapters (except the final project in chapter 6) one of the following kits is required:

• CY8CPROTO-062-4343W (PSoC™ 6 Wi-Fi BT Prototyping Kit)
• CY8CPROTO-062S2-43439 (PSoC™ 6 Wi-Fi BT Prototyping Kit)
• CY8CKIT-062S2-43012 (PSoC™ 62S2 Wi-Fi BT Pioneer Kit)

To do the final project, you must have the CY8CKIT-062S2-43012 kit plus one of the following shield boards:

• CY8CKIT-028-SENSE (Shield Board containing sensors, microphones and an OLED display)
• CY8CKIT-028-TFT (Shield Board containing sensors, a microphone and a TFT display)

An ammeter is required if you want to measure current consumption for the low-power exercises in chapter 5:

• Ammeter (for low power chapter exercises)
