Feb 29, 2016 · 2.5 Amps is just a very high, safe figure -- it assumes the pi itself may use up to 1 Amp (which obviously it doesn't, if goobering's charts are correct) and the USB could use up to 1.2 Amps. However, considering what's on the market you might as well get a 2.5 Amp supply.

Mar 11, 2015 · Raspberry Pi 2 - Are 64GB UHS SDXC cards supported? I'm using a 64GB Hama UHS-I SDXC card formatted with the SD Card Formatter 4.0 with NOOBS 1.4 on it. It doesn't seem to want to boot. I have both

Feb 27, 2016 · The B+ had a single core Broadcom BCM2835 Arm 6, with 512MB of RAM. the Raspberry Pi 2 (is newer) has a quad core BCM2836 Arm 7, with 1GB of RAM. As a result of the quad core CPU the Raspberry Pi 2 has a higher current draw. Adafruit put together a nice comparison of the two, that includes a section detailing how to tell them apart.

Apr 12, 2016 · I've just received a Raspberry Pi 2 and tried to insert the micro SD card, but for some reason the mechanism doesn't appear to be working correctly. You hear a click and can observe the card pushing fully into the slot. However, the card simply springs out and can be pulled free without having to push the card in again.

Nov 26, 2021 · I do not recommend using Docker on Pi Zero. There are not much docker images available for ARMv6. To save you from trouble you should use Pi 2 or newer or Pi Zero 2. Also you should consider the limited memory amount of Pi Zero 2. All full-size Pis have at least 1GB. Otherwise follow the installation instructions on the official docker page:

Feb 20, 2013 · The high usage figure is reasonable for a Raspberry Pi 2 Model B, or an original Raspberry Pi model B. The model A+ and Pi Zero consume the least power. Even at relatively high electricity prices you are looking at < $0.02 per day of running the box.

Jul 14, 2015 · Raspberry changed something since November 2016. here is the noob instruction to get this problem fixed . sudo su raspi-config 1) Choose first 'update' 2) In advanced options -> expand_root file system. 3) interfacing options -> ssh [enable] 4) change_locale [your country-UTF8] and if you still here, it's good to change the timezone as well

Feb 28, 2020 · FWIW, if you have a Pi CM4 with the IO board (as opposed to a regular Pi 4), you could add a PCI Ethernet NIC (with multiple ports), by using the on-board PCI-E slot, to make a multi-homed device. The official IO board already has an on-board gigabit Ethernet port, so by simply adding a dual NIC PCI card, you would then have the three Ethernet ...

Jul 25, 2014 · Use an SPI-Ethernet adapter (the same one people use on the Pi Zero). Raspberry Pi people prefer using the one with the ENC28J60 chip on it. Use both of the above, get three ethernet ports (two above + 1 built-in)

Feb 4, 2015 · The PS2 core, is the MIPS R5900 basing off of the MIPS III, which uses 64-bit instruction sets instead of the older versions that use the basic 32-bit instruction sets; although the Emotion Engine CPU is built to process 128-bit instead of 64-bit This forces the Raspberry Pi 2 to begin both the emulation of 128-bit instruction sets, THEN ...
