DAVEGA X hardware v1.1
A few weeks back, there was a small update to the DAVEGA X hardware. The input voltage is changed from 5V to 3.3V.
When the unit connects to WiFi, power consumption increases and that results in a sudden voltage drop. The built-in voltage regulator sometimes does not manage to handle this, which results in the unit shutdown and reboot.
Taking 3.3V directly from VESC prevents the problem. This has been tested with various VESC types and is working well.
The latest orders already received the updated hardware.
An important thing to keep in mind is that the v1.1 must not be accidentally connected to 5V input since that would destroy the MCU. All the new units are shipped with correct cables. It’s still worth double checking since a human error can happen.
Here’s the connection diagram for v1.0 and v1.1 and for various VESC types:
Note that connecting the USB cable is still safe with the v1.1 units since the built-in voltage regulator is then utilized.
