Ghani Lawal- Have option to limit and monitor the amount of current flowing through the motor drive circuitry
- nFault pin pulls low during fault conditions:
- VM supply undervoltage
- Charge pump undervoltage
- Out Overcurrent
- Thermal shutdown
- Motor driver has max recommended output current of 3.5A
- Motor has max stall current of 2.8A - https://www.dfrobot.com/product-1458.html
- torque at this current is 0.8kgf.cm, rated torque is .2kgf.cm
- Extrapolating linearly, rated current is 0.7A
- Will let I_Trip = 1.5 A
- if V_ADC = 5V -> R_trip = 3.33kohm
- if V_ADC = 3.3V -> R_trip = 2.2kohm
- Need GPIO for Control input mode, Awake_sleep mode and maybe nReset as well
Motor Controller
A project log for SurvBot
Remote controlled robot that surveys the environment it is travelling in. PCBs for the Robot and Remote Controller will be original designs
