README.mdElevator-Controller-PCB
A KiCad PCB that drives a small elevator model using two servo motors, controlled wirelessly over an NRF24L01 radio link.
Overview
The board is built around an Arduino Nano that:
- Receives commands over an NRF24L01 2.4GHz radio module
- Drives two servos (M1, M2) for elevator car/door motion
- Drives a buzzer for audible feedback
- Reports status via three LEDs (Power, Debug, Error)

Questions
How big is the ElevatorController PCB?
It measures 70 × 70 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ElevatorController use?
26 parts, built around the S8050. 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 ElevatorController KiCad files?
From the Delibot-Lab/Elevator-Controller-PCB repository on GitHub, at the commit this page was made from: the board is elevatorController/elevatorController.kicad_pcb and its schematic elevatorController/elevatorController.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ElevatorController design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
