Open RC Spotter is an open-source ESP32 telemetry and data logger for RC cars and toys - CNX Software

Jake Wachlin (Energy Labs) has designed the Open RC Spotter, an open-source ESP32-based telemetry and data logger for RC cars, trucks, and other RC toys. The platform logs synchronized GPS position, acceleration, gyroscope, steering, throttle, battery voltage, temperature, and lap timing data to a microSD card, while also supporting live telemetry over Wi-Fi and ESP-NOW.We have previously written about telemetry and data-logging hardware designed for full-sized vehicles, such as the Macchina A0 ESP32 CAN board, which supports OBD-II diagnostics and RaceChrono integration. Compared to that, this ESP32-based logger is designed for RC cars and trucks, combining GPS, IMU, PWM monitoring, and onboard data logging in a compact ESP32-based platform.Open RC Spotter specifications:

Wireless module – ESP32-WROOM-32E-N4

SoC – ESP32 dual-core Tensilica LX6 microcontroller @ up to 240 MHz with 520KB SRAM

Storage – 4MB flash

Wireless – 2.4 GHz WiFi 4 and Bluetooth 4.2 BR/LE connectivity, built-in PCB antenna
