Size 2 Tibbo Project PCB (TPP2)

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

Offering 3 tiles for a total of 6 Tibbit module and 6 Tibbit connector sockets, the TPP2 can implement configurations with up to four simple serial ports, up to 12 relays, or up to 24 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 2 Tibbo Project Box (TPB2). The board is also compatible with and can be assembled into the TPB2L, which features a 320x240 TFT LCD and a 4-button sensor keypad.

The TPP2 is perfect for systems with a medium number of I/O lines. Since the board can control a TFT display and a keypad, it is suitable for applications requiring a human-machine interface (HMI).

The board is an ideal choice for data collection and autoID projects, as well as factory, shop, data center, hotel, and home safety, security, and automation applications.

The TPP2 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 (TPP2 provides a dedicated GA1000 socket).

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