We are currently making more boards (all types) and we plan on making more to be available. Every new unit since last batch has the new rev 2.2 board with many options for ESTOP and main power.
So ‘Stand By’ We are trying to help those who need remote switches on outside of their robot case or in different position. Thanks.
I am sorry if I missed anybodies request so far, we are really super busy with lots of other stuff so ask again on support@ubiquityrobotics.com and put Attention Mark please in the subject perhaps
