Size 3 Linux Tibbo Project PCB (LTPP3)

LTPP3 is a Linux-based Tibbo Project PCB belonging to the Tibbo Project System (TPS) line. The board is based on a powerful 1GHz Cortex-A8 Sitara CPU and has five UARTs, as well as two CAN controllers.

Offering 7 tiles for a total of 14 Tibbit module and 14 Tibbit connector sockets, the TPP3 can be used to create TPS configurations 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.

Tibbo envisions a variety of use scenarios for the LTTP3. In one scenario, the board is purchased with an Embedded AggreGate license. Embedded AggreGate turns the board into a compact AggreGate server, thus allowing for rapid development and deployment of IoT applications.

In other scenarios, the user takes advantage of Tibbo OS for Linux (LTiOS) and Node.js, which come preinstalled on the board. The former allows the LTPP3 to execute Tibbo BASIC and Tibbo C applications. The latter gives you access to the entire world of Node.js programming.

This embedded Linux system can be used as a bare board or assembled into a size 3 Tibbo Project Box (TPB3).

The LTPP3 is supported by our Online Configurator. The configurator allows defining custom TPS systems, which can then be ordered from our online store.
