La Raspberry Pi Foundation has released new news, because recently he unveiled the introduction of a new board, the Raspberry Pi 3 Model A +.
The Raspberry Pi 3 Model A + comes with the continuation with the development of the series «A». The "A +" model is positioned as a simplified and more compact version of the "B +" model.
These Raspberry Pi A models are focused on use in embedded solutions and systems that require minimal power consumption, that do not require an Ethernet connection and only a USB port.

What's new in the Raspberry Pi 3 Model A +.
Its recently announced new release takes the Pi 1 Model A + and elevates it to the specs of the Pi 3, incorporating the same 64-bit quad-core processor with a clock speed of 1.4Ghz and a wireless network of 2.4 / 5Ghz as its flagship Pi 3 Model B +.
Following the specs of the traditional Model A, it bypasses an Ethernet port and has one USB port instead of the four found on the B +.
Features of the new Raspberry Pi Model A +.

- Production lifespan: The Raspberry Pi 3 Model A + will remain in production until at least January 2023.
Differences from the 3 B + and 3 A + model
The differences in performance and power specs can be a bit the same, though In terms of presentation, the Model 3 B + is the most convenient.
This model It comes with a 8GHz ARMv1,4 quad-core processor, Wi-Fi, Bluetooth, Ethernet (max 300Mbps), USB 2.0, and HDMI.
As for the new Raspberry Pi 3 Model A + it is supposed to be a smaller model, but with most of the advantages of the Model B +.
It has similar specifications, Except you get 512MB of RAM instead of 1GB, there is only one USB 2.0 port and the Ethernet port is gone.
Plus the significantly more efficient 64-bit CPU and doubling the size of the RAM, the hallmark of the new A + model is the built-in support for wireless 802.11.b / g / n / ac (2.4GHz and 5GHz) and Bluetooth 4.2 / BLE.
The hardware padding changes also show improved support for booting from USB drives and better power management and temperature control (when the chip temperature is 70 °, the frequency is 1.4GHz, but if the temperature exceeds 70 °, the frequency decreases to 1.2GHz and in the chip voltage).
But that's it.
If you don't need a ton of RAM or Ethernet, it's a surprisingly decent mini-computer.
Even if you've played with a Raspberry Pi in the past, recent models have come a long way. The processor is now powerful enough to handle demanding tasks.
Sure, it will take longer to transcode a video, unzip a large file, or launch an emulated game on a Raspberry Pi than on a laptop.
However if you want a fanless computer that runs 24/7, it's hard to find something cheaper. Docker works quite well on it, making it even easier to maintain if it's containerized.
When will the Raspberry Pi 3 A + be available?
This new model announced by the Raspberry Pi Foundation It will go on sale in December for $ 25.
And as usual it will have direct Raspbian support. Although they can also use the NOOBS user interface to install different distributions on the SD card
