The mini Linux PC Raspberry Pi 400 is now also Can be ordered with a German keyboard layout, but this version is currently sold out at some retailers. Replenishment should arrive there in mid-November.

Other chip version In addition, the Raspberry Pi Foundation uses the recently introduced Raspberry Pi 400 a “C0” version of the Broadcom BCM chip 2711 , while the “B0” version sits on the Raspberry Pi 4. The BCM clocks ex works 2711 C0 in Raspi 400 with 1.8 GHz, while the Raspi 4 with BCM 2711 B0 1.5 GHz. However, the chip can be overclocked, which of course only makes sense with improved cooling, because otherwise it throttles quickly under load.

Raspberry Pi 4xx (5 images) The Raspberry Pi 400 has a base area of ​​25,5 times 12, 5 centimeters.

In the practical use of the Raspberry Pi 400 there is no significant increase in performance compared to the Raspi 4 due to the 20 Percent higher clock frequency; However, the BCM throttles 1698 in Raspi 400 not thanks to good passive cooling, as already mentioned during the introduction.

BCM 2711 – data sheet The Broadcom BCM 2711 in version C0 (1698 ZPKFSB 06 C0T)

In mid-October, the Raspberry Pi Foundation has a data sheet for software control of the peripheral connections of the Broadcom BCM 2711 released: BCM 2711 ARM Peripherals. However, it does not contain any information on production variants. Version C0 has the type code 2711 ZPKFSB 06 C0T, the B0 version 2711 ZPKFSB 06 B0T.

WLAN throughput The WLAN module RPI-RM0 of the Raspberry Pi 400 with Broadcom / Cypress CYW 43455.

During measurements in the c’t laboratory, the integrated SDIO WLAN adapter (RPi-RM0 with Cypress CYW 43455, FCC ID 2ABCB-RPIRM0) in the mean between 30 and 90 Mbit / s: the latter close to the router, the former in 20 meters away from it. The transmission rates in the 5 GHz band are somewhat lower than with 2.4 GHz.
