How to connect an Arduino Nano to the ES-200B

To get the ES-200b working you need to cut the exposed wires from the GPS tracker. Warning these wires have different color codes depending if you are going to cut it before or after the waterproof plug. For my scooter I cut it on the GPS tracker side. On the other side the Black and Red wires are still the same. the BTN wire is yellow and the TX is blue I believe.
The Black is ground (GND) The red wire is the VIN 42 volt from the battery. The Blue is called the BTN and this is just to turn on the motor controller. It requires a constant 3.3v. The yellow is TX and will need to be connected to the RX of the Nano. The green is the RX line and is not required but I hooked it up anyways just in case you want some input from the motor controller.
So the first step is to hook up a Buck convertor to the Red (VIN) and black wires (GND) this will step down the relatively high voltage from the battery to something the Arduino can use. Because the battery is 42v you will need a special Buck Convertor that can handle all that voltage. I used an LM2596 based convertor board from amazon. A XL7015 type break out might be a better choice. Make sure to adjust the voltage below 5v. Now connect the Arduino ground to the buck convertor and the buck's + to the Arduino's VIN
Next connect the yellow TX of the tracker to the Arduino's RX pin. Now connect the Blue (BTN) wire to pin number 5 on the arduino or more simply to the Arduino 3.3v out. Last upload the included arduino .ino file to the nano and away you go.
If you cant get a hold of buck convertor right away its OK to connect the arduino to a USB battery. That will do the trick.

Hello, very nice job.

I have a quesion, i have Buck convertor to the Red (VIN) and black wires (GND)

https://fr.aliexpress.com/item/33025917509.html?spm=a2g0s.9042311.0.0.27426c372oO2Zs

I connect it on an ESP32 whithin RemoteXY code. All done ! The ES200 D is running very well.

The problem appear after 3 weeks. The red wire dont have any voltage between black and red...

I have a second scooter for spare, the same issue on some weeks... 2 controllers KO whith

this connection. I suspect the Buck conertor. But i don't know why?? Have tou an idea? when i charge the scooter,

the display shows the load and no error but whatever I communicate with the RX pin of the controller like before nothing happens, the scooter don't turn on. :-(

thx for reading and may be helping.

Hi there, where is the Post/Project for setting up with RemoteXY? I have a ESP32 with Wifi wanting to upload firmware and run from my Android Phone. Cannot find the old link you put up. And what is the main Project .ino file to use when uploading to the Adruino?

help!! Please reply to the question from "patrik.hry"

Have you connected it do the cables going directly from scooter or from gps tracker located in the black box? Thank you.

Are you sure? yes | no

I am happy to report that this is working on my Jump ES-200B aka ‘Tank’. just took it for my first spin after figuring it out and easily hit 12km/h (20.3mph) on the flats. I’m a huge robot at 113 kilos (250lbs) and it does pretty well at speed. Steep hill climbing is not great for obvious reasons. Used included code and Arduino Nano Every board and IDE for macOS. Worked great! So many thanks!
