Raspberry Pi 3 A+

by Raspberry Pi

Pint-sized power! The Raspberry Pi 3 Model A+ packs all of the processing and wireless power of the 3 B+ into a significantly smaller package.

It has a 64-bit 1.4GHz quad core processor, 512MB of RAM, fast dual-band 802.11 b/g/n/ac wireless LAN, and Bluetooth 4.2.

It works great with our HATs and pHATs, and we've got brand-new Pibow Coupé cases, in four colours including RAINBOW!

  • 1.4GHz 64-bit quad-core ARM Cortex-A53 CPU (BCM2837)
  • 512MB RAM
  • On-board wireless LAN - dual-band 802.11 b/g/n/ac (CYW43455)
  • On-board Bluetooth 4.2 HS low-energy (BLE) (CYW43455)
  • 1 x USB 2.0 port
  • 40 GPIO pins
  • Full size HDMI 1.3a port
  • Combined 3.5mm analog audio and composite video jack
  • Camera interface (CSI)
  • Display interface (DSI)
  • microSD slot
  • VideoCore IV multimedia/3D graphics core @ 400MHz/300MHz

With the ARMv8 processor it can run the full range of ARM GNU/Linux distributions, including Snappy Ubuntu Core, as well as Microsoft Windows 10 IoT edition.

You'll need the latest NOOBS image for the Wireless LAN and Bluetooth drivers to be installed. We sell a pre-imaged NOOBS card.

Adding one of our three-port USB hubs with ethernet will let you use additional USB devices and add wired networking.

Way faster processing!

The previous A+ had a single-core 700MHz CPU, but the addition of the quad-core 1.4GHz BCM2837 SoC with improved thermals to the Pi 3 A+ gives a huge performance boost. The VideoCore is clocked at 400MHz for video processing and the 3D graphics processor runs at 300MHz.

Now with fast wireless!

The Pi 3 A+ now has wireless! It's the same fast, dual-band wireless chip (CYW43455) as the Pi 3 B+, with 802.11 b/g/n/ac wireless LAN and Bluetooth 4.2.

The dual-band 2.4GHz and 5GHz wireless LAN enables faster networking with less interference (although the higher bandwidth has less range), and the new PCB antenna technology should allow better reception.

Bluetooth allows you to use a wireless keyboard/trackpad without extra dongles, keeping things nice and tidy.

GPIO and layout

The GPIO header remains the same as the previous A+ (and the Pi 3 B+ and Zero / Zero W), with 40 pins. Be aware that the new metal shielding on the wireless circuitry and the SoC may cause shorts against larger components on the underside of HATs, pHATs, and SHIMs. In the first two cases, standoffs will help; in the latter, a couple of small pieces of insulating tape or Kapton tape will prevent any shorts.

Simply the best and most powerful MCU on the hobbiest market at the moment. Even the arduino setup works out of the box. So far I've tested I2C, SPI, Audio, USB audio, Rotary Encoder and SDIO card libs - all work flawlessly and fantastically well. Running some audio spectrum processing the Arm CMSIS libs for a 4096 FFT takes around 412us (0.4ms) including mag squared calcultions and all the various buffer copies - amazing stuff!

As someone dealing with microcontrollers for the first time the teensy is excellent. Incredible performance for the size and while it doesn't have a massive community the examples that are part of the ide are really detailed.

Got one as soon as they were back in stock. Arrived quickly and well packaged. Couldn’t be happier with this amazing board/service!

Nice little board with quite a bit of juice and a lot of connection options. Really nice that you can use it as a USB host, and that it has pinouts for ethernet too. Haven't tested all the stuff it can do, as I mainly use mine to run a DirtyWave M8 tracker/synth.

Fast delivery & well packaged. Using the Teensy 4.1 to run the "headless" version of the M8 tracking software - works great and setup was way easier than I expected.

I have soldered on the pins, and its running on my breadboard. I probably have not yet accessed 1 per cent of what this fantastic little board can do... I'm using Visual Studio Code with PlatformIO, all seems good so far....

Absolutely wonderful card. Incredibly fast and stable. Lots of RAM and lots of flash memory. It is also possible to expand both RAM and flash by soldering circuits on the underside of the card. With good code examples and a content-rich forum. Works well to write code in both Arduino and Visual Studio. I really love this circuit

This is a high end microcontroller. The USB host interface works very well with some good examples in the library. You can solder two PSram chips on the bottom for a Whopping 16GB of ram!!

So far the board works and powers on. I'm yet to use other features on it but Very excited. Order was quick and will use this website more often
