Size 2 Tibbo Project PCB (TPP2), Gen. 2

Gen. 2 Performance Highlights

The TPP2(G2) is a high-performance upgrade to the original TPP2. Here is a list of important improvements:

• 32-bit architecture (vs. 16-bit architecture of the TPP2)
• 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)
• 1.5-3.0 times faster graphics
• 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)
• 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 2 Tibbo Project PCB (TPP2), Gen. 2 runs Tibbo OS (TiOS) and is programmable in Tibbo BASIC and Tibbo C.

The TPP2(G2) is perfect for systems with a medium number of I/O lines. The board can optionally control a TFT display and a keypad, so it is suitable for applications requiring a human-machine interface (HMI).

This product can be used as a bare board or assembled into a Size 2 Tibbo Project Box (TPB2). For HMI applications, the board can also be assembled into the TPB2L, which features a 320x240 TFT LCD and a four-button sensor keypad.

Featuring three tiles for a total of six "M" and six "C" sockets, the TPP2(G2) can implement configurations with up to four simple serial ports, up to 12 relays, or up to 24 opto-inputs, pulse-width modulation (PWM), or open-collector outputs.

The TPP2(G2) is perfect for data collection and automatic identification (AutoID) projects, as well as factory, shop, data center, hotel, and home automation applications. The board contains enough "C" sockets to accommodate temperature, humidity, pressure, ambient light, and shock sensors simultaneously. With the appropriate Tibbits, the board can even control legacy IR devices by emulating traditional IR remote controls.
