I’ve been hard at it recent weeks to get a good design here. I’m happy with the results so far and it feels like some key decisions have been made regarding protection of the device and user.
. 10.16mm and 7.62mm Pitch Barrier Terminal block options on the inputs.
. ALL inputs fused and transient protected.
. Shunt Monitors Powered from 5V line, 5V line transient/over-voltage protected.
. DC-DC Buck Supply now a plug-in module, compatible with cheapo modules or the one I’ll be putting out at the same time for a bit more. Buck power supply input fused and transient protected.
. 7.62mm Barrier Terminal Block mount available for connecting a 5V supply of your own, skipping the DC-DC buck altogether.
. Reverse polarity protection made through the same diode/fuse combinations used for transient and over-voltage protection.
I plan to put the board out with some literature for safe use, demo installs, a video perhaps.
Literature would include how to select the correct terminal blocks and shunt for a particular Amperage, making sure the board doesn’t get too hot. The external shunt option always there also, and I’ve made provision for using shielded shunt leads.
All other features as described on the github page.
Feedback welcome, as my next stage will be a crowd funding application!
