【Silicon Labs Development Kit Review】+ Unboxing Experience [Copy link]

 

First of all, I would like to thank EEWORLD and Silicon for giving me the opportunity to experience the EFM32PG22 development kit and begin to have a comprehensive understanding of Silicon labs ' MCU .

1. Unboxing

The first impression after opening the box is that it is smaller than we thought. Let's take a look from the outside to the inside.

The outer packaging uses dark color on the front and red on the back, which looks more delicate.

After opening the outer packaging, you can see that there is a short USB cable. It should be limited by the size of the packaging box, so a shorter cable is provided. There is a note on the bottom box indicating the address of the development kit. The other one is the development kit motherboard.

The motherboard is very small and can be placed in the palm of your hand.

Although it is small in size, it has a very high degree of integration, which is the so-called small but complete.

1. It integrates many sensors: temperature and humidity sensor; ambient light check sensor; Hall effect sensor; 6 -axis inertial sensor, etc.

2. Onboard USB interface SEGGER J-Link simulation debugger;

3. User LED and user button;

4. PDM stereo left and right microphones;

5. Button battery slot.

Such a small board integrates so many things, and the manufacturer has put a lot of effort into it, just to give everyone a better experience.

Silicon Labs ' EFM32PG22 (PG22) microcontroller. This is a new microcontroller . The development kit is mainly exhibited as a cost-effective and rich cornerstone for energy-saving embedded applications. The button battery holder makes the PG22 kit a small stand-alone system, simplifying the development of battery-powered products based on the EFM32PG22 . The manufacturer is thoughtful so that you can experience the low power saving effect. The PG22 development kit can be quickly programmed using a USB Micro-B cable and the on-board J-Link debugger . With the help of a USB virtual COM port, a serial connection to the target application can be achieved. The PG22 development kit is supported by Simplicity Studio and a board support package (BSP) to allow users to get started quickly.

2. Power on

The system is pre-installed with a program to flash LED . After the USB is connected , the LED starts to flash.
