Rocket Telemetry Board

Open-source telemetry system for amateur rockets built around the Heltec Wireless Stick Lite (V3) (ESP32-S3 + SX1262 LoRa). The project includes the onboard flight computer, the LoRa ground receiver, a Flask-based ground station dashboard, KiCad PCB files, Gerber manufacturing outputs, and OpenRocket simulations.

Questions

How big is the PlacareceptorP PCB?

It measures 50 × 80 mm and has 2 copper layers, 1.6 mm thick.

What parts does the PlacareceptorP use?

11 parts, built around the MPU-6050. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the PlacareceptorP KiCad files?

From the Dertrox/rocket-telemetry-board repository on GitHub, at the commit this page was made from: the board is hardware/pcb/kicad/placareceptorP.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the PlacareceptorP design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
