Size 3 Tibbo Project PCB (TPP3), Gen. 2

Gen. 2 Performance Highlights

The TPP3(G2) is a high-performance upgrade to the original TPP3. Here is a list of important improvements:

• 32-bit architecture (vs. 16-bit architecture of the TPP3)
• Five to 80 times better performance, depending on the calculations and variable types
• Seven times faster GPIO manipulation
• Three times larger available user SRAM (66KB vs. 22KB)
• Two times larger flash memory (1MB for TiOS/code + 1MB for the file system vs. 1MB total for TiOS, code, and file system)
• 2.2 times lower power consumption (100mA vs. 220mA)
• Four-channel ADC
• The ability to update TiOS firmware and compiled Tibbo BASIC/C app over-the-air (this requires the WA2000 and an iOS or Android device)

Introduction

The Size 3 Tibbo Project PCB (TPP3), Gen. 2 runs Tibbo OS (TiOS) and is programmable in Tibbo BASIC and Tibbo C.

The TPP3(G2) 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 programmable logic controllers (PLC) 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.

Offering seven tiles for a total of 14 "M" and 14 "C" 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, 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).
