This issue of Infineon’s hands-on class will be presented by engineer Jenson from Infineon, who will provide a comprehensive introduction to the PSoC™ 62 with CAPSENSE™ evaluation kit (hereinafter referred to as the PSoC 6 RTT development board) and its modular development kit. Let’s explore this flexible and versatile MCU kit with Jenson!
The PSoC 6 RTT development board is a development kit for developers to use during the evaluation and testing phases, which has received unanimous praise from developers since its launch. At the same time, we have received a request from developers to design some modular components that can be freely added to enhance the flexibility of the development board, such as adding wireless connectivity and sensor integration. After a period of joint research and development, we, along with our partners, have finally completed the modular MCU development kit that meets this request: it includes the development kit motherboard co-developed by Infineon and RT-Thread, model PSoC™ 62 with CAPSENSE evaluation kit; as well as the wireless expansion board and CSK (sensor) expansion board developed in collaboration with Beino, models CYW43012 adapter and CSK adapter, respectively.
Unboxing Experience
The kit box contains a PSoC 6 RTT development board motherboard and a USB Type-A to USB Type-C cable. The development board has two USB interfaces: the upper DAP port is for programming and debugging, while the lower MCU port is the USB function interface for PSoC™ 62. From top to bottom, there are three buttons: the MODE button is used to switch the debugger’s mode; USER is the user button; and the bottom one is the RESET button. Next to the buttons is the PSoC™ 5 chip, used for USB to SWD, USB to I2C, UART, etc., enabling programming and debugging of the PSoC™ 62. The 1.27mm pin header on the right of the PSoC™ 5 is used to extend AIROC™ Wi-Fi & Bluetooth functionality. In the middle is the PSoC™ 62 chip, which uses a 68-pin QFN package with 2MB flash memory. The far right is the CAPSENSE™ slider, with Arduino expansion headers on both sides. Below is a dip switch for selecting 1.8v or 3.3v levels, compatible with chips powered by different voltage levels than AIROC Wi-Fi & Bluetooth. The back of the development board features an SD card slot and a level conversion chip.
Hands-on Testing
We powered the development board via Type-C and downloaded a simple application program. The development board supports ModusToolBox™ and RT-Thread Studio IDEs for development. After modifying the BSP using ModusToolBox™, we downloaded a CAPSENSE slider project. Once the download was complete, sliding a hand on the slider could light up the LED and display relevant logs. We could also use RT-Thread Studio to download a boot routine to run the RT-Thread OS.
Next, let’s take a look at the CYW43012 Adaptor accessory component, which is a Wi-Fi & Bluetooth sub-board jointly developed by Infineon and Beino. We attach the Wireless Adaptor to the motherboard, ensuring the orientation of the sub-board is correct, with the antenna facing the slider side. After connecting, we can use ModusToolBox or RT-Thread Studio for PSoC™ 6 + Wi-Fi & Bluetooth development.

Next, let’s look at the CSK adaptor accessory component, which is used to extend Infineon’s official CSK (Connected Sensor Kit) development board, supporting millimeter-wave radar, carbon dioxide sensors, and pressure sensors. The CSK adaptor expansion board also features a small proximity sensing sensor that can be evaluated in conjunction with CAPSENSE™ functionality. We can add the CSK component on top of the CYW43012 Adaptor and then add the millimeter-wave radar sensor to achieve a combination of millimeter-wave radar + CAPSENSE™ + Wi-Fi & Bluetooth functionality.

This motherboard is also compatible with other Arduino interface sensors, actuators, wireless devices, displays, etc.
Application Scenarios
The PSoC™ 62 series is suitable not only for capacitive touch and general MCU scenarios but also for motor drives, smart locks, electronic cigarettes, HMIs, AI, and various smart application scenarios. Infineon also provides AIROC™ Wi-Fi chips, Bluetooth chips, or Wi-Fi & Bluetooth combo chips, millimeter-wave radar, carbon dioxide sensors, etc.
Through this Infineon hands-on class, I believe everyone has gained a basic understanding of the PSoC 6 RTT modular development kit. The ultra-low power PSoC™ 6 MCU features dual-core M4/M0+ and PSA security functions, making it an ideal choice for IoT devices and various consumer electronics, especially for battery-powered devices.
