We offer many ready-to-use apps, among them a serial-over-IP (SoI) app, Modbus Gateway app, and Sensor Hub app.

Size 3 Tibbo Project PCB (TPP3)

Not recommended for new designs. Consider the TPP3(G2) board instead.

Tibbo Project System overview
Size3 Tibbo Project PCB

Size 3 Tibbo Project PCB is a Tibbo BASIC/C-programmable board belonging to the Tibbo Project System (TPS) line.

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 four full serial ports, up to 25 relays, or up to 47 control lines, such as opto-inputs, PWMs, or open-collector outputs.

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

Size 3 Tibbo Project PCB is ideal for applications requiring no human-machine interface while calling for a significant number of I/O lines and functions. The TPP3 can be used to replace dumb PLC controllers or work as a safety, security, or access control device. The board is also ideal for factory, lab, shop, building, hotel, and home automation projects.

The TPP3 is supported by our Online Configurator. The configurator allows defining custom TPS systems, which can then be ordered from our online store.
