The default pin mappings make it easy to get started, but they can be customized for more specialized applications.
This version ships as a partial kit ; all surface-mount components are installed, but the included through-hole connectors are not soldered in. This version ships fully assembled with connectors soldered in. The compact 1. This version outputs an analog voltage proportional to the motor current, and an extra control input allows for coasting in addition to the driving and braking offered by the other Pololu high-power motor drivers. This product has been replaced by an improved second-generation version , which can be used as a near drop-in replacement despite its much smaller size.

However, because a good motor can have stall currents dozens of times higher than the typical operating current, motors with stall currents that are hundreds of amps can be used with this driver as long as the running current is kept low.
For example, a motor with a 80 A stall current might run well at 8 A, leaving a safe margin for the current to double for several minutes at a time or to triple for several seconds.
If the motor does stall completely for a prolonged period, however, the motor or driver are likely to burn out. Warning: This motor driver has no over-current or over-temperature shut-off. Either condition can cause permanent damage to the motor driver. The motor driver can detect three different fault states, which are reported on the FF1 and FF2 pins. The detectable faults are short circuits on the output, under-voltage, and over-temperature. A short-circuit fault is latched, meaning the outputs will stay off and the fault flag will stay high, until the board is reset RESET brought low.
The under-voltage fault disables outputs but is not latched. The over-temperature fault provides a weak indication of the board being too hot, but it does not directly indicate the temperature of the MOSFETs, which are usually the first components to overheat. The fault flag operation is summarized below. There are four versions of the single-channel G2 high-power motor drivers that share compatible pinouts, and eight versions of the dual-channel G2 high-power motor drivers.
Four of the dual-channel drivers have the form factor of an Arduino shield, but they can also be used with other controllers as general-purpose motor drivers. The following table provides a comparison of the G2 drivers:. Note: As an alternative to these motor drivers, our Simple Motor Controllers have similar power characteristics and offer high-level interfaces e.
There are also nine original high-power motor driver versions. The three CS versions have the same pinout, and the six non-CS versions have the same pinout.
