Use Aux1 and Aux2 with other voltage sources
Closed this issue · 5 comments
I could be a benefit for some users to change the power source for AUX1 & 2 from 12V_REG to V_BAT or other external power-source.
This is mostly for users that want to use higher than 12V to drive equipment on AUX1 & 2
This also applies when the load on Aux exceeds the 1Amp spec. of the 12V regulator.
The idea behind these kind of extensions is to have external "payloads" controlled from the main board via I2C or something similar. This way the payload can have its own power source and possibly even its own board with it's own logic.
But indeed having a easy onboard extensibility mode could be an option too

I understand, seems logical.
My thought was mainly on the scalability of the functions on the board. ie. like the jumper(P13) for internal/external power for the servos and ESC's.
The jumper is just an hack to make things work with power supply... will be fixed in future release of the cape

i would leave the layout for P13 function as-is, i think its more a feature than a hack.
if the jumper function hadnt been there(and 5V and servo power connected together) the 6v from the default hobbyking esc could fry something.
And not all ESC's has built in 5-6V out, and then need 5v in to drive the logic part of the ESC. this is common on boat esc's and high-voltage esc's(ie 20-50V esc's)
Done as of controllerboard 2.5
