Raspberry Pi 3 Model B B+
Some key features and benefits of the Raspberry Pi 3 Model B and B+ Raspberry Pi 3 Model B Features:
- **Processor**: It is powered by a Broadcom BCM2837, 64-bit quad-core ARM Cortex-A53 processor running at 1.2 GHz.
- **Memory**: It is equipped with 1 GB LPDDR2 SDRAM.
- **Wireless connectivity**: It has built-in Bluetooth 4.1 and 802.11n wireless networking.
- **Interfaces**: It includes 4 USB 2.0 ports, 1 Ethernet port, microSD card slot, HDMI port and a 40-pin GPIO header.
- **Power**: It is powered by a 5V/2.5A power adapter.
Raspberry Pi 3 Model B+ Features:
- **Processor**: It also uses a Broadcom BCM2837B0, 64-bit quad-core ARM Cortex-A53 processor, but the running frequency is increased to 1.4 GHz.
- **Memory**: Equipped with 1 GB LPDDR2 SDRAM, the same as the B model.
- **Wireless connection**: Enhanced wireless connection capabilities, supporting dual-band 2.4/5 GHz 802.11.b/g/n wireless networks and Bluetooth 4.2/BLE.
- **Interface**: Maintains the same interface configuration as the previous generation, but the Ethernet port is upgraded to Gigabit, which theoretically provides a higher data transfer rate.
- **Power**: Improved power management circuit to accommodate higher-power USB devices, but still uses a 5V/2.5A power adapter for power.
- **Heat dissipation design**: Adopts a better heat dissipation design, including a pre-installed heat sink to help deal with heat dissipation under high load.
Advantages summary:
- **Performance improvement**: B+'s increase in CPU frequency brings better computing performance.
- **Enhanced wireless connection**: B+ supports dual-band Wi-Fi, which makes wireless connections more stable and reliable, and the Bluetooth version has also been updated.
- **Network performance**: Gigabit Ethernet support allows faster data transmission.
- **Cooling improvements**: Better cooling solutions help to keep the system running smoothly for longer periods of time.
These improvements make the Raspberry Pi 3 Model B+ a more powerful and flexible choice, especially for applications that require better wireless connectivity and network performance. Whether it is a home media center, a lightweight server, or the core of an Internet of Things (IoT) device, the B+ provides stronger performance and support.
