I've got the very basic version, this has hardwired connectors for the cables rather than a 3pin plug. The code programs fine, just run into the problems above.
Thanks for the fix Jason, D7 is currently pulled low by R2, what issues were you seeing with the data? Did the module comms work fine, but the controller didn't...
Thanks for the detail, which way around did you put the diode ?

Hi ArchGalileu, the circuit in Colin's branch is the same as this one - its only the code thats different. I've not got a farnell list I'm afraid - but...
> 7 Watts will go very very hot... Agreed it will get hot!
> The BOM in the readme says components cost is around £5.50 but on farnell a 3R3 50 Watts resistor is more than 6£ :-/ Yes although I brought a...
The code uses PWM so would want to switch the relays on and off very quickly. Would you be monitoring the balance load temperature?
You could keep the in board MOSFET and PWM but just use another larger external MOSFET instead of a relay?
Low, the PWM is triggered every millisecond.
