Delta

Delta is a minature, custom board that remotely control vehicles, connecting to the Onboard Diagnostics (OBD-II) port and streaming real-time onboard sensor data such as:

• Speed
• Acceleration
• Gyroscopic Tilt
• Throttle & Steering Position
• Gear
• Engine RPM

and integrating external cameras and sensors.

Delta supports WiFi and Bluetooth LE, running a dual-core ESP32-S3R8V based on the 32-bit Xtensa architecture. The current prototype is only 32mm * 37mm with single-sided assembly, packing a ton of components into an incredibly small area. Delta can be powered by a computer through the USB Type-C port or independantly with a 12v car battery.
