Yesterday, the first photo of the Raspberry Pi 3 single-board computer was leaked, attracting widespread attention from domestic and foreign media. Although the leaked images are not very clear, we can still analyze and predict the various upgrade indicators of the Raspberry Pi 3 compared to the Raspberry Pi 2. Let’s unveil the mysteries of the Raspberry Pi 3.
-
The size remains unchanged from the Raspberry Pi B+/2B, and the GPIO interface (40P) and position are also unchanged. From this point, it can be inferred that the official move is to maintain compatibility with the Raspberry Pi B+/2B interface, so friends who have purchased expansion boards need not worry about compatibility issues.
2. At the request of many players, the official has finally added Bluetooth and WIFI functions to the Raspberry Pi 3. The antenna uses a ceramic antenna, but unfortunately, the WIFI only supports 2.4G 802.11n. The antenna is located in the position of the LED light in the old version, and the RUN 2P interface has been moved to the network port position:
3. The back of the Raspberry Pi 3 has added a J5 debugging interface socket (JTAG), but it is uncertain whether the official version will retain this debugging interface.
4. From various images and official messages, the Raspberry Pi 3 will use a 64-bit ARM chip with a frequency of 1.2 GHz. This will be the first 64-bit product in the Raspberry Pi family. The memory remains the Elpida B8132B4PB-8D-F RAM chip (1GB). Such hardware upgrades also mean that the Raspberry Pi system will be comprehensively upgraded and cannot use the current version.
