Hey everyone,

I’ve been tinkering with my ZhiDou D1 and built a simple diagnostic display using an ESP32 microcontroller.
It connects to the car’s CAN bus and displays key parameters like speed, voltage, current, and temperature in real time.

The goal was to make something compact, easy to mount, and affordable — basically a plug-and-play way to keep an eye on what’s going on under the hood.

Here are a few pictures of the current prototype:

Awesome idea would it work on the d2 too?

Hi Ekin,

It should work more or less on the D2 model as well. The only issue is that the page showing individual cell voltages won’t be fully correct in this version—it currently displays only the first 24 cells, while the D2 model has more.

I’ve sent it to someone who has a D2 model, and they’ll be testing it soon.

Hi Ekin and others,

Currently it works only with D1 model as D2/D2s has different pinout and a bit different can messages for errors.
It is possible to update this diagnostic display for it but it has to be different version created.
