1.7.3 General purpose motor control connectors
Jumpers J19, J21 and J23 configure the supply voltages for the J20, J22 and J24 motor
control connectors, respectively, as described in
Appendix C: Jumper settings .
The GP Motor control connectors are compatible with the PowerSpin set of evaluation
boards that are based on monolithic motor control chips. The PowerSpin chip family
includes L6205 -6 -7 -8 and L6235 devices.
