LTPP3(G2)

LTPP3(G2) – Linux Tibbo Project PCB Size 3, Gen.2

The LTPP3(G2) is a Linux-based Tibbo Project PCB belonging to the Tibbo Project System (TPS) platform. The board is based on the powerful quad-core 1GHz Cortex-A7 Plus1 (SP7021) CPU jointly developed by Sunplus and Tibbo.

The LTPP3(G2) features a powerful set of I/O ports located directly on the board. Dual Ethernet ports allow daisy-chaining with other Ethernet devices. Wireless connectivity (through the optional add-on module WA2000) has been expanded to 802.11a/b/g/n/ac and Bluetooth/BLE 5.0, while 4G LTE Cat-1 or NB-IoT is supported through the use of dedicated Tibbits. Also new are integrated HDMI and serial-over-USB console ports, as well as two USB 2.0 Host ports with Type-A connectors and a built-in microSD slot. The board incorporates a power supply with an input range of 8V to 60V, eliminating the need for power Tibbits.

Offering four tiles for a total of eight Tibbit module and eight Tibbit connector sockets, the LTPP3(G2) can be used to create TPS configurations with up to four full serial ports, up to 16 relays, or up to 32 control lines, such as opto-inputs, PWMs, or open-collector outputs.

The LTPP3(G2) can be used as a bare board or assembled into a Size 3 Linux Tibbo Project Box (LTPB3). It also serves as the evaluation board for our Plus1 (SP7021) chip.

The LTPP3(G2) is supported by the TPS Online Configurator through which you can define a custom TPS.
