Size 3 Tibbo Project PCB (TPP3), Gen 2

Tibbo Project System overview

Compared to the original TPP3, gen. 2 board runs 5-80 times faster.

Board's TiOS firmware is currently in BETA release.

Size 3 Tibbo Project PCB, Gen 2 is a Tibbo BASIC/C-programmable board with Ethernet, as well as optional Wi-Fi* and GPRS** connectivity. The board has four UARTs.

Offering 7 tiles for a total of 14 Tibbit module and 14 Tibbit connector sockets, the TPP3(G2) can be used to construct devices with up to four full serial ports, up to 25 relays, or up to 47 opto-inputs, PWM outputs, open-collector outputs, or other I/O.

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

Size 3 Tibbo Project PCB, Gen 2 is ideal for remote automation solutions and applications that require no human-machine interface (HMI) while calling for a significant number of I/O lines and/or functions.

The TPP3(G2) board can be used to replace dumb PLC controllers or work as a safety, security, or access control device. The TPP3(G2) is also ideal for factory, lab, shop, building, hotel, and home automation projects.

The TPP3(G2) 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 GA1000 Wi-Fi add-on (TPP3 provides a dedicated GA1000 socket).

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