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, so you should not count on this fault to prevent damage from over-temperature conditions.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRemapping pins\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAll of the Raspberry Pi’s GPIO pins are broken out along a row of numbered through-holes just below the 40-pin GPIO connector.

This makes it more practical to use the driver with a motor that might only draw a few amps while running but can draw many times that amount (tens of amps) when starting.\u003c\/p\u003e\n\u003cp\u003eFor each motor channel, you can lower the limit by connecting an additional resistor between the VREF pin and the adjacent GND pin; the graph shows how the current limit relates to the VREF resistor value.

Current will continue to circulate through the motor when the driver begins braking, but the voltage on the CS pin will not accurately reflect the motor current in brake mode. The CS voltage is used internally by the motor driver, so to avoid interfering with the driver’s operation, you should not add a capacitor to this pin or connect a load that draws more than a few mA from it.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eReal-world power dissipation considerations\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe MOSFETs can handle large current spikes for short durations (e.g. 100 A for a few milliseconds), and the driver’s current chopping will keep the average current under the set limit.

The actual current you can deliver will depend on how well you can keep the motor driver cool. The driver’s printed circuit board is designed to draw heat out of the MOSFETs, but performance can be improved by adding a heat sink or airflow. For high-current installations, the motor and power supply wires should also be soldered directly instead of going through the supplied terminal blocks, which are rated for up to 16 A.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan style=\"color: #ff0000;\" data-mce-style=\"color: #ff0000;\"\u003eWarning\u003c\/span\u003e: This motor driver has no over-temperature shut-off.

Instead, it enters a quiescent state where it continues to eat 30 to 50mA, sometimes more depending on connected peripherals. This is wasteful and can become an issue in battery-powered systems.\u003c\/p\u003e\n\u003cp\u003eThe PiWatcher TB can be programmed to fully cut power to the Raspberry Pi after a certain delay of inactivity. For example, you can tell the PiWatcher to cut power 10 seconds after a shutdown command has been issued, giving the Raspberry Pi enough time to cleanly power off.\u003c\/p\u003e\n\u003cp\u003eThe second issue with power management has to do with the ability to recover from situations where a Raspberry Pi becomes stuck in an unrecoverable state. While in theory, this should not happen, a long-running Raspberry Pi can get 'stuck' or 'freeze', due to software or hardware failures or even environmental factors such as heat. In some cases the least unsatisfactory approach to deal with this issue is to simply switch off and on again the Raspberry Pi, enabling the application to continue and\/or send out an alert.\u003c\/p\u003e\n\u003cp\u003eThe PiWatcher TB can be programmed to automatically power cycle a Raspberry Pi if it does not receive a 'heartbeat' from the device after a user-selectable delay. This can allow some critical applications to continue to operate without human intervention.\u003c\/p\u003e\n\u003cp\u003eFurthermore, the PiWatcher TB can be programmed to wait for a certain delay, ranging from a few seconds to about 36 hours, before rebooting your Raspberry Pi after a shutdown. The PiWatcher has an LED. When the Raspberry Pi is powered on, the LED is continuously on. When the Raspberry Pi is powered off, the LED blinks slowly.\u003c\/p\u003e\n\u003cp\u003eThe PiWatcher also has a useful micro tact-switch. When your Raspberry Pi is running:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eA long press (5 seconds) on the button will fully power off the Raspberry Pi.\u003c\/li\u003e\n\u003cli\u003eA short press (half a second) on the button will send a software signal that can be exploited for user-defined purposes.\u003c\/li\u003e\n\u003cli\u003eWhen your Raspberry Pi is shut down, a short press on the button will restart the Raspberry Pi.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe user can connect an external switch as an alternative to the micro tact-switch provided on the board. This is useful when putting the Raspberry-Pi in an enclosure, where the on-board switch becomes hard to access. The external switch must be connected to the BUTTON_ALT and GND pins shown in the picture below.
