Freematics OBD-II Data Logger Kit Upgraded

The popular Freematics OBD-II data logger kit #3 has just got better. After coming back from the Maker Faire Bay Area, we upgraded the kit by replacing the 2.8″ TFT LCD screen shield with a newly designed 3.2″ TFT LCD shield with built-on I/O sockets and optional Bluetooth module. The new TFT LCD based on SSD1289 is perfectly supported by the latest revised version of MultiLCD library now. This makes screen larger (also faster) and eliminates the need for a I/O shield in the middle of TFT LCD shield and Arduino MEGA board. The Bluetooth (BLE or BT 2.1) capability is provided by a CC2540 module soldered on the back of the shield which is connected to Arduino MEGA’s Serial3.

Making a SD card GPS logger with Arduino and MTK3329 GPS module

Finally I got the MTK3329 GPS module connected with Arduino. The module works in 1Hz mode by default. I referred to Adafruit’s test sketch to switch the module to 10Hz mode and the update speed rocks!
