Breakout boards - a plea for consistency!

[MikeF]

I recently built a multi-sensor node, with 3 I2C breakout boards: HTU21D (temperature, humidity), BMP180 (barometric pressure), BH1750FVI (light level). These all had different pinouts (pins at bottom, left to right):

HTU21D: Vcc > GND > SDA > SCL
BMP180: 3.3V > SDA > SCL > GND > Vcc (3.6V - 6V)
BH1750FVI: ADDR (connect to GND) > SDA > SCL > GND > Vcc

For those of us using stripboard (rather than designed PCBs), it would be good to have a consistent standard! (Oh, and the Ceech board I use has Vcc > SDA > SCL > GND.)

Try using the MySensors "standard".

I'm not sure I understand - I was talking about mounting these on a stripboard, where all the connections are different:

All of those came from different places so it's pretty unlikely anyone here can help...
