TI Carnival+ Building the foundation for a secure IoT: Unboxing the TI SimpleLink Wi-Fi CC3220S [Copy link]

The model of the development board is TI SimpleLink Wi-Fi CC3220S (CC3220S-LAUNCHXL). Note that this board has a series, suffix: S means security, which enhances the security of the board. F stands for Flash, XIP flash memory. The one tested this time is S, without F, but with external serial Flash.

The above picture The packaging is the same black small carton as always for Launchpad.

The box is much smaller than the first MSP430 Launchpad, very compact. In fact, this is an advantage. People who work in electronics usually can't fit a bunch of hardware, so it's better to be compact and take up less space.

The information label on the back says Made in China. Although the board is directly mailed from the United States, it cannot escape being made in China. It would be even better if one day China can "smartly manufacture" it.

There are two partitions on the left and right, one for the board and one for the Micro USB power cable. The cables are packed in a plastic bag, and the board is wrapped in an anti-static bag. When mobile phones used Micro USB, Launchpad used Mini USB cables, but now they have been replaced with Micro USB, and mobile phones all use Type C. The speed of development of consumer electronics is really not to be underestimated.

In addition, there are two pieces of paper with no substantive content. Apart from the two Thank Yous, the useful content is probably those few URLs. In fact, you only need to remember the TI official website (www.ti.com), and you can search for specific devices or evaluation boards on the official website.

Take a closer look at the board. The original Launchpad red PCB. The board is divided into two parts as usual. The upper part is the XDS110 emulator, which is connected to the PC via Micro USB and has both power supply and data communication. The lower part is the CC3220S part. Of course, there is also a 32Mbits flash chip. Most of the expansion IOs are led out on the left and right sides, which is also a feature of Launchpad. On the left below are two sensors, acceleration and temperature. In the middle is the wifi antenna, which can be connected externally in addition to the onboard antenna. In the lower right corner are 3 LEDs. This is a single-chip wireless MCU, which is equivalent to integrating ARM Cortex-M4 with network processor, wireless transceiver, etc. As a hybrid digital-analog chip, it can simplify most Internet of Things (IoT) designs. After all, according to the current development situation, WiFi connection has become very popular. If you want to connect devices to the cloud, WiFi is the simplest and most direct way. It is worth mentioning that the hardware encryption of this chip supports multiple algorithms such as AES, DES, 3DES, SHA2, MD5, CRC, etc. It supports multiple protocols such as HTTPS SSLv3, TLS1.0, TLS1.1, TLS1.2, and maintains a low power consumption level. It can be said that it has laid a good hardware foundation for the construction of a secure Internet of Things.
