Raspberry Pi Raspberry Pi 4 Model B, 2 GB review

The Raspberry Pi 4 Model B with 2 GB, built on a Broadcom BCM2711 quad-core Cortex-A72 at 1.5 GHz, with two USB 3.0 and two USB 2.0 ports, Gigabit Ethernet, dual-band Wi-Fi and the standard 40-pin header.

By Jean-Benoit Buisson

The bottom line The bare board, described by processor, radios, ports and header. Everything needed to run it — power, storage, case, operating system — is outside this listing and has to be bought or known.

The Raspberry Pi 4 Model B listing, bullet by bullet

Five bullets: a Broadcom BCM2711 quad-core Cortex-A72 64-bit SoC at 1.5 GHz; 1, 2, 4 or 8 GB of SDRAM depending on model; dual-band 802.11ac Wi-Fi, Bluetooth 5.0, BLE and Gigabit Ethernet; two USB 3.0 and two USB 2.0 ports; and the standard 40-pin GPIO header, compatible with earlier boards.

A bare board against the kits

No supply, no card, no case. The two Raspberry Pi 4 kits reviewed here add those parts and cost more. The bare board suits someone who already owns them, and the listing makes clear by omission that nothing else is included.

RAM listed for the whole range

The second bullet names every memory size. The title fixes this offer at 2 GB, which is the figure to rely on.

What a Pi 4 needs that the listing omits

A power supply of adequate rating, a microSD card with an operating system, and often a heatsink. None is described, and each has to be chosen separately.

Availability

At the last look-up, the German, French, Italian and Spanish Amazon stores were asking 71 € to 73 €.

It is sold in the American and British Amazon stores as well, in their own currency, which the euro figures above leave out on purpose.
