M5311 NB-IoT China Mobile IoT Evaluation Board

Overview

The M5311 evaluation board test version
was a chip given away at a China Mobile promotional event. I just did some random tweaking to see if it could run
the verification: Verified and usable.

Friendly reminder: Beware of telecom fraud (Last year, when I cancelled my SIM card at a China Telecom branch, they told me I didn't need to manually cancel it. Now, more than a year later, they're still chasing me for money before I even posted this. Even if they use my credit score to blackmail me, I will never pay the cancellation fee. This is blatant telecom fraud).

LED drive circuit
Generally, constant current drive circuit is better for LED. Now I want to use voltage to control the current through LED and thus control the luminous intensity of LED. I am looking for a suitable ci
Asking Xiangshui City, can the I2C of STM32 be directly connected to 5V devices?
Xiangshui City, recently an instrument case selected the STM32F101VBT6 chip, and encountered some problems. 1. Can the I2C of STM32 directly connect to 5V devices, and require working at 400K? 2. Can
Filtering
How to better filter out glitches in voltage signals? Is there any other method besides RC first-order filtering?
Ask a question about compilation. How to compile a MAP file under VxWorks?
In PSOS, after compilation, a MAP file will be generated as a memory mapping table, through which the value of a variable in the running program can be viewed. Can such a file be compiled in VxWorks?
[GD32L233C-START Review] 3. GPIO, EXTI
This time, we use the four LEDs and the "Wakeup" button on the GD32L233C-START board to conduct experiments, and learn about the GPIO and EXTI (external interrupt resources) of GD32L233CCT6 through si
Some special uses of AD6
1. Globally modify the character size. Generally speaking, the component number and key parameters are marked near the components of the formal PCB,but some pure SMD circuit boards are relatively smal
