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

Tibbo Project System overview
Size 3 Linux Tibbo Project PCB, 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 an optional add-on module) has been expanded to 802.11a/b/g/n/ac and Bluetooth/BLE 5.0. Cellular connectivity is provided through the use of Tibbit #45 (4G (LTE) Cat-1) or Tibbit #46 (Cat-M/NB-IoT). 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.

Ubuntu-Based Distribution for End-User Applications and Rapid Prototyping

Ubuntu is one of the most popular Linux variants in the world. Thanks to its widespread adoption, it boasts a vast user base and offers a wide variety of community resources for all manner of projects, big and small.

Tibbo's Ubuntu-based distribution is perfect for when you just want to plug the LTPP3(G2) board in and get going with your work. An accompanying Personal Package Archive (PPA) provides libraries, drivers, and an Out-of-Box Experience (OOBE) script that simplify the board's configuration and software development.

Yocto-Based Distribution for
Mass Deployment and Production Devices

The Yocto Project aims to improve the process of creating embedded Linux distributions for specific applications. Because it provides sophisticated tools for defining what components should be included in a Linux build, it is recommended for our customers working on Plus1-based mass-produced products or planning large, repeatable Linux deployments.

By building your Linux with Yocto, you can significantly decrease the resulting package size, as well as improve your product's reliability by removing unnecessary components that so often litter Linux distributions.

Yocto is quite complex, and so it is not for everyone. If your goal is just to use our LTPP3(G2) board, we recommend (at least starting with) our Ubuntu-based distribution.

  1. These LEDs are not visible when the board is placed inside the LTPB3.
  2. This operating temperature range applies only to the bare board @ 12/24/48VDC. After adding Tibbits and/or the wireless add-on module, the entire system should be retested at the desired input voltage range to determine the overall operating temperature range.
