Add 2nd I2C port to Tiny/TWOG
It can be handy to have a second I2C port on the TWOG v1.00 or Tiny v2.11. This allows to separate flight sensitive sensors (e.g. IMU) from payload sensors.
ADC2/J8 can easily be modified to have the same pinout as the original I2C/J6 port.
remove R12 replace R13 with a 10k resistor cut the trace between R13 and R15 connect the (then) open end of R13 with 3.3V at R17 connect J8_IN_ADC_6 with J7_BOOT (SDA1) connect J8_IN_ADC_5 with J2_CTS (SCL1) secure the thin wire with small dots of hot glue
The original I2C/J6 is i2c0 and ADC2/J8 becomes i2c1.
