Raspberry Pi 3 Model B+ launched with 1.4GHz quad-core processor, dual-band WiFi, gigabit ethernet over USB 2.0, Bluetooth 4.2, and Power over Ethernet for $35
Despite selling over 14 million of its low-cost DIY computing boards, the Raspberry Pi Foundation adheres to a slow release cycle.
Context & Ripple Effects
The Model B+ is an incremental refresh of the 2016 Raspberry Pi 3, keeping the same quad-core architecture and the same $35 price while upgrading the connectivity story: dual-band WiFi, gigabit ethernet (throttled by the USB 2.0 bus it rides on), Bluetooth 4.2, and Power over Ethernet. The Foundation's stated pace matters as much as the specs — after 14 million boards sold, it still refuses to chase annual release cycles.
That discipline has defined the product line since the $35 Pi 2 set the pattern in 2015, and the related coverage shows where it leads: an $25 A+ cut-down later in 2018, a $35 Pi 4 in 2019, and finally a $60 Pi 5 in 2023 — the first visible break with the fixed-price formula.
First-order effects
- Buyers get a meaningful networking upgrade at an unchanged $35: dual-band WiFi and PoE make ceiling- and wall-mounted deployments (kiosks, access points, thin clients) practical on a single cable.
- The gigabit ethernet port is capped by USB 2.0 bandwidth, so real-world throughput lands well below the headline number — a compromise that keeps the board's bill of materials at the $35 target.
Second-order effects
- Power over Ethernet pulls the accessory ecosystem along with it: HATs and powered switches become the default way to deploy Pis at scale, deepening lock-in to the Foundation's board rather than generic SBC alternatives.
- The $35 anchor forces competing single-board vendors to differentiate on raw specs rather than price, since matching the Foundation's cost structure means matching its nonprofit economics.
Third-order effects
- Holding one price across four generations built the installed base that made the Pi the default board for embedded and industrial projects — but the 2023 move to $60 for the Pi 5 signals the fixed-price era giving way to market-rate pricing as the platform professionalizes.
- If the slow-release cadence holds, each generation becomes a longer-lived standard for commercial deployments, shifting the Pi's center of gravity from hobbyist DIY toward infrastructure hardware.
The trend: Single-board computing is drifting from the Raspberry Pi Foundation's fixed-$35 price discipline toward spec-tiered, market-rate pricing as the platform matures from hobbyist DIY into industrial infrastructure.
