Introduction

Size 2 Tibbo Project PCB (TPP2) runs Tibbo OS and is programmable in Tibbo BASIC and Tibbo C.

TPP2 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. For HMI applications, the board can also be assembled into the TPB2L box, which features a 320x240 TFT LCD and a 4-button sensor keypad.

Featuring 3 tiles for a total of 6 "M" and 6 "C" sockets, the TPP2 can implement configurations with up to four simple serial ports, up to 12 relays, or up to 24 opto-inputs, PWM, or open-collector outputs.

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

Hardware features

Powered by Tibbo OS (TiOS).

10/100BaseT auto-MDIX Ethernet port (automatic detection of "straight" and "cross" cables).

Optional Wi-Fi interface (requires the WA2000 add-on module).

Optional GPRS interface (requires Tibbit #47).

3 tiles with 24 general-purpose I/O lines:

 - 6 sockets for Tibbit modules;

 - 6 sockets for Tibbit connectors;

 - 1 extra socket for Tibbit #37;

 - 4 Tibbit module sockets have UART capability:

     - Baudrates of up to 921,600bps;

     - None/even/odd/mark/space parity modes;

     - 7/8 bits/character;

     - Full-duplex mode with RTS/CTS and XON/XOFF flow control;

     - Half-duplex mode with direction control;

     - Encoding and decoding of Wiegand and clock/data streams.

 - Each module socket has an interrupt capability;

 - 1 module socket has PoE capability.

 - 4 remappable synchronous serial ports with SPI and I2C modes.

Onboard buzzer.

Connectors for the TFT LCD and sensor keypad of the TPB2L.

RTC with a backup supercapacitor.

22KB SRAM for Tibbo BASIC/C variables and data.

1MB flash memory for TiOS, application code, and file system.

2048-byte EEPROM for data storage.

Eight onboard LEDs:

 - Green and Red main status LEDs;

 - Yellow Ethernet link LED;

 - Five blue LEDs (for Wi-Fi signal strength indication, etc.).

Software-controlled PLL for selecting high or low speed.

Reliable power-on/ brown-out reset circuit.

Power: 220mA @ 3.3V (100Base-T mode, full speed).

Dimensions (LxW): 94 x 94mm.

Operating temperature range: -40 ~ +70C.

Firmware is upgradeable through the serial port or network.

Tibbo BASIC/C application can be debugged through the Ethernet LAN.

CE- and FCC-certified.
