NEW PRODUCT: RASPBERRY PI 3 MODEL A+ ON SALE NOW AT $25

TL;DR: you can now get the 1.4GHz clock speed, 5GHz wireless networking and improved thermals of Raspberry Pi 3B+ in a smaller form factor, and at the smaller price of $25. Meet the Raspberry Pi 3 Model A+.

 

Raspberry Pi 3 Model A+

Long-time readers will recall that back in 2014 the original Raspberry Pi 1 Model B+ was followed closely by a cut-down Model A+. By halving the RAM to 256MB, and removing the USB hub and Ethernet controller, we were able to hit a lower price point, and squeeze the product down to the size of a HAT.

Small but perfectly formed

 

Although we didn’t make A+ form-factor versions of Raspberry Pi 2 or 3, it has been one of our most frequently requested “missing” products. Now, withRaspberry Pi 3 Model B+ shipping in volume, we’re able to fill that gap by releasingRaspberry Pi 3 Model A+.

Phenomenal cosmic powers! Itty-bitty living space

Raspberry Pi 3 Model A+ incorporates most of the neat enhancements we made to its big brother, and features:

  • A 1.4GHz 64-bit quad-core ARM Cortex-A53 CPU
  • 512MB LPDDR2 SDRAM
  • Dual-band 802.11ac wireless LAN and Bluetooth 4.2/BLE
  • Improved USB mass-storage booting
  • Improved thermal management

Like its big brother, the entire board is certified as a radio module under FCC rules, which in turn will significantly reduce the cost of conformance testing Raspberry Pi–based products.

 

In some ways this is rather a poignant product for us. Back in March, we explained that the 3+ platform is the final iteration of the “classic” Raspberry Pi: whatever we do next will of necessity be less of an evolution, because it will need new core silicon, on a new process node, with new memory technology. So 3A+ is about closing things out in style, answering one of our most frequent customer requests, and clearing the decks so we can start to think seriously about what comes next.
