This repository contains the complete open-source hardware, firmware, data, documentation, and supplementary media package for the manuscript entitled “An Open-Source BLDC Motor Test Bed Utilizing ESC Telemetry for Cost-Effective Educational Laboratories” submitted to HardwareX. The project presents a low-cost BLDC motor characterization test bed intended for undergraduate engineering laboratories and educational motor testing. The platform replaces expensive commercial dynamometer components with off-the-shelf e-bike hardware, a Votol EM-50 electronic speed controller (ESC), an ESP32-based data acquisition and control unit, and a floating-caliper torque measurement mechanism using a low-cost load cell and HX711 amplifier. ESC-native telemetry is used to obtain voltage, current, speed, and temperature data, reducing the need for external electrical instrumentation. This archive includes firmware for ESP32 control and telemetry acquisition, wiring diagrams, ESC connector pinout tables, mechanical assembly documentation, bill of materials, calibration procedures, raw and processed experimental data, plotting scripts, assembly photographs, and supplementary videos. The dataset supports validation of telemetry accuracy, torque calibration, uncertainty analysis, steady-state performance characterization, dynamic load-step response analysis, and model-versus-experiment comparison. The platform was designed to improve accessibility, transparency, and reproducibility of BLDC motor experiments in teaching laboratories. All materials are provided to allow reviewers, researchers, instructors, and students to inspect, reproduce, modify, and adapt the hardware for educational and laboratory characterization purposes. The hardware design files are released under the CERN Open Hardware Licence Version 2 – Strongly Reciprocal. Firmware and supporting scripts are provided as open-source materials for reproducibility and further development.
