Next up I want to look at the BMP280 module (sensor).  The sensors that I ordered came as bare boards again, in that the header pins were not pre-soldered.  

Interesting! My BMP280 board has 6 pins, (all that I saw at the time I ordered it were also 6 pin) the additional 2 being CS and MISO/SDO as the module can use both I2C and SPI modes. By default the address is 0x76 but it can be changed to 0x77 by tying pin 6 to VCC. Alternatively, the address could be changed to 0x76 in the Meduino sketch, Werk_AG??

An example of the module I have is here:

Can I ask where you got your 4 pin module please Mark - and does it use the 0x77 address??

Hi Allan,  Trust you are well.   I bought my 280 baro modules from eBay.  Below is the URL for this modules that I bought:
