These boards are based on the work that John Bostwick has done on his design for a SMD version of the heatermeter. John was so kind to send me his Eagle files and I used his files as the foundation of this design.
The main difference is that this is a 4 thermistor version. Also the complete routing is changed, groundplanes are added and some components have been moved.
I love the white PCB's although they have one huge drawback, they need to be cleaned much more thoroughly than darker boards.
All SMD components bottom side.
All SMD components top side.
Bottom finished.
Top finished. The display will have to move to the bottom side of the board, but this is a prototype board and the display is much easier to remove this way if the board turns out to be a dud.
And yes it fits...... but only when you cut the 14 extra pins off the RPI header.
Succes! The HM booted up first time and all seems to be working just fine. Tomorrow I will do a test run but so far I'm a very happy camper.
Bryan and John, thanks for the excellent work!
