6.5 Option: Pseudo DC-Motor mode
The velocity of the motor in this mode is changed through a constant voltage at the General Purpose
input. The operational voltage is 7...28V.
6.5.1 Changes required for DC motor mode operation
It is advised to connect an external voltage divider to the GPI pin, as depicted.
However, there are two free places for 0805 SMD resistors to be equipped directly on the module
TMCM-013.
To enable this mode solder use resistors as follows:
Attention: Do not try to make changes on the board until you are absolutely sure.
