I have recently created a drone quadcopter pcb, with no ERC and DRC errors .

[Telemetry] Legacy avionics project for SR1500 rocket.
CDB is an open-source printed circuit board by Serra-Rocketry, from the Serra-Rocketry/old-cdb repository on GitHub. It is a 2-layer board of 50 × 120 mm with 17 parts on 33 nets, routed with 166 tracks and 0 vias.
It is built around the ESP32-C3, BMP280 and RFM95W, with the BC547 among its other parts. Its parts include 5 capacitors, 5 ICs, 3 connectors, 1 resistor and 1 diode. It belongs with the ESP32 and RISC-V boards of this library.
Este projeto é o computador de bordo (CDB) para o foguete SR1500 da equipe de foguetemodelismo Serra Rocketry. O CDB utiliza sensores e módulos para monitorar a altitude, localização GPS, e controlar a abertura do paraquedas para garantir um voo seguro.
Os códigos contidos em /extras são apoios ao desenvolvimento. Esses códigos são funcionais e testados.
Os códigos contidos em /testsão apoios ao desenvolvimento, como etapas para construção do código final.

This repository contains various versions of the sensor station PCB used by Meetjestad.



It measures 50 × 120 mm and has 2 copper layers, 1.6 mm thick.
17 parts, built around the ESP32-C3, BMP280, RFM95W and BC547. 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.
From the Serra-Rocketry/old-cdb repository on GitHub, at the commit this page was made from: the board is hardware/CDB/CDB.kicad_pcb and its schematic hardware/CDB/CDB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask Serra-Rocketry before reusing the design.
