| − | TODO: Unrelated to VTLUUG
| |
| − |
| |
| − | Raspberry Pi is a series of inexpensive single board computers. At one time, it was suggested that we build a [[VTLUUG:Beowulf Cluster|Beowulf cluster]] out of [[Raspberry Pi cluster|Pis]].

| − | === Raspberry Pi 1 ===
| |
| − | The Raspberry Pi A, A+, B, and B+ boards, the Pi Zero, and the Compute Module feature a 700MHz ARM11 armv6hf processor, with the following distinctions between the models:
| |
| − | * A: 1 USB, no ethernet, 256MB RAM. Uses SD cards. $25.
| |
| − | * A+: Smaller than the A, 1 USB, no ethernet, 256MB RAM. Uses microSD cards. $25.
| |
| − | * B (Version 1): 2 USB, 10/100 ethernet, 256MB RAM. Uses SD cards. $35.
| |
| − | * B (Version 2): 2 USB, 10/100 ethernet, 512MB RAM. Uses SD cards. $35.
| |
| − | * B+: 4 USB, 10/100 ethernet, 512MB RAM. Uses microSD cards. $35.
| |
| − | * Compute Module: No onboard ports, in a SODIMM form factor. 256MB RAM. Also has 4GB of eMMC. $30 (in batches of 100).

| − | === Raspberry Pi 2 ===
| |
| − | The Raspberry Pi 2 Model B is a new model, featuring a quad core ARM v7 processor running at 900MHz. It has 4 USB ports, 10/100 ethernet, 40 GPIO pins and 1GB of RAM. Uses microSD cards.
| |
| − |
| |
| − | === Raspberry Pi 3 ===
| |
| − | The Pi 3 model B was introduced in early 2016, and features a 64-bit ARM processor running at 1.2 GHz, and featuring integrated Bluetooth and WiFi. Otherwise, it is identical to the Pi 2 model B.

| |
| − | === Other Notes ===
| |
| − | Raspberry Pis do not have onboard storage (except for the Compute Module), and they do not
| |
| − | have onboard WiFi or Bluetooth (excepting the B 3).
| |
| − | All Pis (except for the Compute Module) support 3.5mm audio out (poor quality, but useable),
| |
| − | HDMI out supporting 1080p30, and composite SD video out. Some also support I2S audio out.
| |
| − | All Pis feature the VideoCore IV GPU, which is fairly powerful given the rest of the components.
| |
| − | It's roughly as powerful as the GPU in the iPhone 4s.
| |
| − |
| |
| − | == Software ==
| |
| − | The Pi can run various distros of Linux, as well as BSDs and some other Unixes ported to ARM.
| |
| − | The main distro is Raspbian, which is based off of Debian Jessie. The Pi also supports Arch
| |
| − | Linux ARM, OpenELEC, and RISC OS.
| |
| − |
| |
| − | The Pi 2 can also run Ubuntu Snappy Core, Ubuntu MATE, and windows 10 IoT Core.
| |
| − |
| |
| − | The Pi 3 is limited at the moment, because it uses a 64bit version of the ARM instruction set.
