About the LTI PCB

LTI is an open source Raspberry Pi PCB design by KXR-UCF, published on GitHub. It is a 2-layer board measuring 65 × 56 mm, with 6 components from 3 distinct parts.

Its main chip is the Raspberry Pi, from the Raspberry Pi family. Other key parts include the HiLetgo ADS1256 Module. By type, the board carries 4 connectors and 2 ICs.

It belongs with the dev boards & breakouts designs in this gallery, and the repository also holds 1 earlier revision of it.

From the project

Ground support software for KXR static fires. This repository contains all code running on the DAQ & Controls systems.

PCB designed and documented by Ethan Voth

A simple PCB to interface up to four load cells with a Raspberry Pi using this HiLetgo ADS1256 board and four JST S4B-XH-A connectors. Includes solder bridges to select separate data lines (DRDY, CS, PDWN) when connecting two boards at the same time.

This board will be used to facilitate high-speed data acquisition for rocket motor static fires, interfacing with multiple load cells and possibly a pressure transducer (PT). Data acquisition is a key responsibility of the Knights Experimental Rocketry (KXR) Launch Test Infrastructure (LTI) team, which…

LTI: common questions

What microcontroller does the LTI use?

The LTI is built around the Raspberry Pi, from the Raspberry Pi family.

How big is the LTI PCB?

The LTI measures 65 × 56 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the LTI?

6 components, from 3 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the LTI design files?

From the KXR-UCF/LTI repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the LTI design in my own project?

The repository has no license, so all rights stay with KXR-UCF. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the LTI without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Raspberry Pi firmware against it before you order a PCB.
