On Monday this week, the Raspberry Pi Foundation announced the Raspberry Pi 3, boasting a 1.2GHz 64-bit quad-core ARM Cortex-A53 CPU, along with built-in 802.11n wireless LAN and Bluetooth 4.1.
The Pi 3 is fully backwards-compatible with earlier models of the Raspberry Pi. The main physical difference is the position of the power and activity LEDs, which have moved to the other side of the SD card socket to make room for the wireless LAN and Bluetooth antennae. As such, the light holes on the Astro Pi flight case no longer line up if you’re using a Pi 3. To solve this, we have produced Pi 3-compatible versions of the two middle sections of the 3D-printable flight case. The heatsink and lid don’t need to change.
