Size 3 Linux Tibbo Project PCB (LTPP3)

ltpp3-flat

Introduction

Size 3 Linux Tibbo Project PCB (LTPP3) comes preloaded with our own, highly polished distribution of Linux that is derived from the Red Hat line.

The TPP3 is ideal for applications that require no human-machine interface while calling for a significant number of I/O lines and/or functions.

Offering seven tiles for a total of fourteen "M" and fourteen "C" sockets, the LTPP3 can be used to construct devices with up to five full serial ports, up to 25 relays, or up to 51 control lines, such as opto-inputs, PWMs, or open-collector outputs.

The generous number of available Tibbit sockets means you can increase your system's versatility by offering multiple power supply options, such as +5V, +12V, PoE, etc. You can also install multiple power supply Tibbits to increase total available power or provide redundancy.

This product can be used as a bare board, or assembled into a Size 3 Tibbo Project Box.
