- Onboard 3-axis accelerometer for orientation, tilt and movement monitoring
- 40% better TiOS and floating-point (FPU) operations performance
- 25% faster GPIO manipulation
- Close to double the available user SRAM (130KB vs. 66KB)
- Two times larger flash memory (2MB for TiOS/code vs. 1MB)
- Four times larger file system (4MB vs.1MB)
- 5V power supply protection (e-fuse) on 5V terminal block
- Enhanced layout for power delivery to Tibbits
- Higher isolation level for isolated Tibbits
Introduction
The Size 2 Tibbo Project PCB (TPP2), Gen. 3 runs Tibbo OS (TiOS) and is programmable in Tibbo BASIC and Tibbo C.
The TPP2(G3) is perfect for systems that require secure connectivity to cloud services, such as Microsoft Azure IoT Hub, thanks to the device being capable of an outgoing TLS 1.2 secure TCP socket. Having onboard temperature and accelerometer sensors enable the design of fail-safe scenarios and a range of applications that need tilt, orientation or constant movement detection.
The TPP2(G3) is also great 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(G3) 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(G3) is excellent for secure 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, and ambient light. With the appropriate Tibbits, the board can even control legacy IR devices by emulating traditional IR remote controls.
TPP2(G3) can be configured to have diverse connectivity options, including Wi-Fi/BLE, Ethernet, LTE, and NB-IoT. Industrial interfaces, such as RS232/485/422, and Wiegand are also available through Tibbits.
