[Anxinke NB-IoT Development Board EC-01F-Kit] 1. Unboxing and Hardware Appreciation [Copy link]

I would like to thank EEWorld and Acre for giving me the opportunity to review the NB-IOT development board.

After receiving the express package, I opened it immediately. The packaging of the development board was normal. I could clearly see the three major items: the development board in an anti-static bag, the telecom SIM card, and the paddle antenna. As shown in the picture:

Back side photo of the development board

And SIM card and antenna

7 rows of pins with 2.54 spacing on both sides, the pins are as follows

The NC pin is marked IO7 on the back.

There are NB indicator light and Link indicator light, as well as PWR and RST buttons on the front. One side of the button is the micro USB interface, and the other side of the indicator light is the SMA socket with external screw and internal hole, which can be connected to the antenna or extension line antenna.

The SIM socket on the back can be opened and the SIM card needs to be placed.

The chip on the back is CH340C, which should realize the USB to TTL function, and the 1117-3.3 DC step-down chip, which provides 3.3V voltage.

I don't understand, what is the input voltage of the 1117-3.3 DC step-down chip, is it from a few V to 3.3?

The USB port is usually 5V down to 3.3

Looking forward to the follow-up evaluation, a lot of information has been collected, praise
