Size 3 Tibbo Project PCB (TPP3)
Introduction
The Size 3 Tibbo Project PCB (TPP3) runs Tibbo OS (TiOS) and is programmable in Tibbo BASIC and Tibbo C.
The TPP3 is ideal for applications that require no human-machine interface (HMI) while calling for a significant number of I/O lines and/or functions.
The board can be used to replace dumb PLC controllers or work as a safety, security, or access control device. The TPP3 is also ideal for factory, lab, shop, building, hotel, and home automation projects.
Offering seven tiles for a total of 14 "M" and 14 "C" sockets, the TPP3 can be used to construct devices with up to four full serial ports, up to 25 relays, or up to 47 opto-inputs, pulse-width modulation (PWM), or open-collector outputs.
Further, the generous number of available Tibbit sockets means you can increase your system's versatility by offering multiple power supply options, such as +5V, +12V, PoE, etc. You can also install multiple power supply Tibbits to increase total available power or provide power redundancy.
This product can be used as a bare board or assembled into a Size 3 Tibbo Project Box (TPB3).

- io — handles I/O lines, ports, and interrupts
- kp — works with matrix and binary keypads
- lcd — controls graphical display panels
- net — controls the Ethernet port
- pat — "plays" patterns on up to five LED pairs
- ppp — accesses the Internet over a serial modem (GPRS, etc.)
- pppoe — accesses the Internet over an ADSL modem
- romfile — facilitates access to resource files (fixed data)
- rtc — keeps track of date and time
- ser — controls serial ports (UART, Wiegand, clock/data modes)
- sock — socket comms (up to 16 UDP, TCP, and HTTP sessions)
- ssi — controls serial synchronous interface channels (SPI, I²C...)
