You always ask for the best microcontroller is suitable for IoT?
We will now learn in this article about the microcontroller is suitable for IoT.
When unsure, it’s STM32L4. It will do everything pretty much, although it’s overkill for a few tasks.
- Can do clean metal jobs well, or has enough resources to run basic RTOSes. several RTOSes support it.
- Very high volume, simple to urge, cheap.
- Wide support for several communications interfaces. BT, WiFi, etc. will run WICED stack if you’re victimization that.
- Excellent low power performance. information sheet current figures are at one.5V. Competitors use DC-DC buck with 3V input to juice the numbers.
- Fastest stimulus from ~1uA sleep mode to full speed I’m conscious of. a handful of microseconds. this is often the killer feature to change low power IoT.
- Free Atollic IDE, that is pro-grade.
- Ultra-low-power mode: 8 nA with backup registers without real-time clock (5 wakeup pins).
- Ultra-low-power mode + RTC: 200 nA with backup registers (5 wakeup pins).
- Ultra-low-power mode + 8 Kbytes of RAM: 195 nA.
- Ultra-low-power mode + 8 Kbytes of RAM + RTC: 340 nA.
- Dynamic run mode: down to 28 μA/MHz.
- Wake-up time: 5 μs.
The Next Best option is ESP32
- It has a built in wifi feature and Python support + It’s too little that it can fit anywhere.
