The Raspberry Pi 3 Model B+ sports a slightly faster 1.4GHz 1 64-bit quad-core ARM Cortex-A53 CPU processor as compared to the 1.2GHz BCM2837 processor on its predecessor’s Raspberry Pi 3 Model B that was launched in 2016. The company strongly advises its users to use a “high-quality 2.5A power supply”, as the Pi 3 B+ needs “substantially more power than its predecessor.” The updated version of the processor in the Pi 3 Model B can reach higher clock frequencies (or run at lower voltages to reduce power consumption), and more accurately monitor and control the temperature of the chip, according to blog post by Raspberry Pi chief Eben Upton. The Raspberry Pi 3 Model B+ also delivers dual-band 2.4GHz and 5GHz wireless connectivity and Gigabit Ethernet over a USB 2.0 connection, which supports 315Mbps (over 3 times speed of previous boards). The dual-band wireless LAN comes with FCC certification that makes it easy and cheap to commercially launch products based on the Raspberry Pi 3 Model B+. The Raspberry Pi 3 Model B+ is currently available for purchase from its website for $35. Further, the company will continue to sell its previous models, Raspberry Pi 1 B+, Raspberry Pi 2B, and Raspberry Pi 3B for $25, $35, and $35 respectively.
