About the OpenLST PCB

OpenLST is an open source PCB design by diegosvs, published on GitHub. It is a 4-layer board measuring 60 × 50 mm, with 86 components from 35 distinct parts.

Other key parts include the LM1117IMP-3.3/NOPB, CC1110F32RHHR, LT1086-3.6, FT5HNBPK27.0-T1 and TLV803SDBZR. By type, the board carries 34 resistors, 30 capacitors, 8 ICs, 6 connectors, 5 inductors and 3 diodes.

It belongs with the rf & radio designs in this gallery.

From the project

The OpenLST transceiver is approximately six by five centimeters with a mass of 20 grams. This radio operates on the UHF band and provides 3.5 kilobit per second user data rates. The design also provides time-of-flight ranging that can be used to estimate link distance. Full design files, including schematics, bill of materials, and layout are available by cloning the git repos at the links below.

OpenLST Reference Hardware ==========================

This repository contains a KiCad project with a hardware reference implementation for the OpenLST. This design is a simplified version of the Texas Instruments CC1110 432 MHz reference design. A 1 watt power amplifier module has been added to increase operating range. The design is intended for use at 437 MHz, however, it may be modified for use at other frequencies.

OpenLST: common questions

How big is the OpenLST PCB?

The OpenLST measures 60 × 50 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the OpenLST?

86 components, from 35 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 OpenLST design files?

From the diegosvs/openLST repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the OpenLST design in my own project?

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