Size 3 Linux Tibbo Project PCB (LTPP3)

Size3 Tibbo Project PCBSize3 Tibbo Project PCB

LTPP3 is a Linux-based Tibbo Project System (TPS) board with Ethernet, as well as optional Wi-Fi* and GPRS** connectivity. The board is based on a powerful 1GHz Cortex-A8 Sitara CPU and has four UARTs, as well as two CAN controllers which make it perfect for industrial control solutions.

The LTPP3 is ideal for embedded solutions and applications that require no human-machine interface (HMI) while calling for a significant number of I/O lines and/or functions. Offering 7 tiles for a total of 14 Tibbit module and 14 Tibbit connector sockets, the LTPP3 can be used to construct devices with up to 25 relays, or up to 47 opto-inputs, PWM outputs, open-collector outputs, or other I/O. Also, LTPP3 is an ideal solution for building embedded Linux systems

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. It is also possible to develop the board's software in node.js and, in the near future, in Tibbo BASIC/C (TiOS porting to Linux is currently under way).

This Linux embedded 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 allowing you to define and order a custom TPS device with Tibbits and options of your choice.

* Requires the GA1000L Wi-Fi add-on (LTPP3 provides a dedicated GA1000L socket).

** Requires Tibbit #47 (GPRS) in tile 1, 2, 3, or 4.

Four Ways to Use the LTPP3 Board

(1) Use LTPP3 With Embedded AggreGate

LTPP3 can be ordered with embedded AggreGate software (licensed purchased separately). Serving as the board’s execution environment, AggreGate lends LTPP3 its immense power of data collection, processing, and visualization. Further, AggreGate provides a uniform, consistent access to external data, devices, and systems using more than 100 supported communications protocols. Via a specially designed middleware C library, embedded AggreGate is also able to access the board’s hardware resources, such as GPIO lines, serial ports, as well as Tibbit modules installed in board’s sockets.

(2) Run Node.js Applications

LTPP3 comes with Node.js preinstalled. We are currently developing node.js modules for accessing the board’s hardware resources and installed Tibbit blocks. You can also utilize many existing node.js modules, such as serialport and Learn more...

(3) Run Tibbo BASIC/C Applications*

Tibbo is currently porting its popular Tibbo OS (TiOS) to Linux. When this work is completed, you will be able to run TiOS as a Linux application and execute existing Tibbo BASIC and Tibbo C code with little or no modifications. Needless to say, the new LTPP3 board crunches Tibbo BASIC and C apps at unparalleled speeds. Learn more about TiOS, Tibbo BASIC, and Tibbo C...
