Research replacement motor controller and 5V regulator. Document on wiki

griswaldbrooks commented 6 years ago

https://www.horizonhobby.com/pdf/ECX01000_Manual_EN.pdf Documentation says that the current esc allows for 20A Need to measure how much the motor draws at 12V

https://www.robotshop.com/en/l298-dual-h-bridge-dc-motor-controller.html Should check with @kiran-mohan as he has one of these.

Regulator https://www.pololu.com/product/2851 This one would probably handle the pi and servo comfortably

griswaldbrooks commented 6 years ago

Need to see the stall current of the servo. This seems to be the chinese choice https://www.amazon.com/eBoot-LM2596-Converter-3-0-40V-1-5-35V/dp/B01GJ0SC2C/ref=pd_lpo_vtph_23_bs_t_1?_encoding=UTF8&psc=1&refRID=RTKPDRXFNBMZ74D3HF65&dpID=61ot3zsbBwL&preST=_SY300_QL70_&dpSrc=detail

Need to consider the load of the teensy

griswaldbrooks commented 6 years ago

Tested the motor throttle motor with power supply. At 12V to 10V or so at idle, the car consumes about 2A with no load, and 3A at load just before stalling the motor.

griswaldbrooks commented 6 years ago

Going with the L298N motor driver and the LM2596 regulator, but going to use two regulators. This decision is driven by the fact that they are so cheap.
