+ User Manual
Power connectors:
Both power inputs on the BeBoPr (board power, stepper power) use the same type of
connector: A 5.08 mm pitch plug that mates the pins on the BeBoPr.
Warning: Because the + board has higher current ratings for the PWM outputs than the
previous BeBoPr versions, a mating power connector with corresponding higher current rating
was selected.
Connector manufacturs often only guarantee their products if you don't mix brands for two
mating connectors. In most cases this is not an issue, but at the high currents used in this
design, every 4 mΩ of resistance in the connection will generate a full Watt of power being
dissipated in the connectors
Although many of these connectors look similar, they may differ in quality and materials used.
Only the connector specified below should be used with the +. Other connectors may
mechanically fit, but will require proper electrical de-rating (i.e. a reduction of the
permitted current). Only go this way if you're have sufficient knowledge and understand the
risks involved.
