Open Auto is an open hardware car sharing hardware platform designed for use by local car-sharing co-operatives and community associations. It originally started out as a Pi Hat, but has now changed into a standalone IOT device based on communications hardware from Particle.
The functionality is simple:
- GPS tracking, allowing the car to be located at all times and used to update the onboard Real-time Clock (RTC)
- RFID card access (125kHz or other frequency, requires an external module), with either CAN-bus or relays to open/close the car doors
- Accelerometer to check driving style (requires an Electron)
- RTC to allow for power saving (wake up once per minute to check status instead of continuously being on)
- CAN bus interface for automotive communication
- Particle Electron/Photon socket for Wi-Fi and/or Cellular connectivity
- An SD card slot for data logging.
- An I2C header for whatever else you want to connect.
We're currently working on a software stack for the Electron/Photon that will allow all the basic functions to be accessed via the particle API.
The design also includes a case, which you can make in 3mm acrylic.
