Your Board uses is really old chips, so maybe better get an newer one:
1. Ouick Alternative to try: set it to the other I2C Adresse 0x69 by grounding the AD0 line. Maybe this will help to get it recognized by pipilot.
You have only one I2C Chip on your Board, the little one is only an VoltageRegulator for 3,3 V.
2. Get an more modern/acurate IMU-Chip, this sometimes has also more Sensors on Board.
What is the alternative for MPU-6050?
The alternatives you can use in place of the MPU6050 include the following:
ADXL335 (3-axis accelerometer)
ADXL345 (3-axis accelerometer)
MPU9250 (9-axis IMU) +++
i would go for the last one.....
3. Try your chip on an esp8266 with this "ESP Easy" Program to check it. Use only the normal SDA/SCL Lines.
You could interface this ESP with Signal K via WiFi and JSON Commads later.
Here is some more Info, https://www.letscontrolit.com/wiki/index.php/MPU6050
---------------------
The board will default to address 0x68. Ground pin AD0 for the alternate address of 0x69 (on the GY-521 the address pin has a pull-up resistor to Vcc).
The pins XCL, XDA and INT are not used and can be left unconnected.
