<p>A couple years ago I bought me a broken “hoverboard”. I had seen the insides of them an notices that they were definitely run on brushless hub motors. All I would need to make use of them were some electronic speed controllers (<abbrtitle="Electronic Speed Controller">ESC</abbr>)
and something to command them. </p>
<p>It’s been a year in our new house and, while organizing and unpacking, I stumbled upon it again. So since it had been a while I thought it would be a good idea to see if anyone had done anything cool with them yet. To my delight, it looked
like someone had written an entire firmware for most generic versions of these. Of course I knew what I had to do.</p>
<p>The button pin is GPIO 00. This is perfect because it lets us boot the esp into bootloader mode. The relay is connected to GPIO 13, and the <abbrtitle="Light Emitting Diode">LED</abbr> is connected to GPIO 12</p>
<p>Folks, I’m going to tell you right now, mistakes were made. It took me <strong>FOREVER</strong> to figure out why my FTDI basic just wasn’t connecting to this thing. I broke out the multimeter, I made sure my voltages were correct, I reinstalled
it to the outlet to see if it still powered on. swapped Tx and Rx. Nothing!… All I have to say now is, make sure you are connecting ground to ground and not “DTR GRN” to ground. GRN looks a lot like GND at first glance. I did however ensure
my FTDI was in 3.3V mode. Make sure you do too!</p>
