power supply on evlservo1 control board

Lukas47 · ‎2025-07-01

Hello,

Is there a way to power the control board of the EVLSERVO1 without using the power board? I would like to just play around with the MCU before connecting to 48V for motor control. The ST-LINK V3SET does not provide any power to the board.

Br,

Lukas

Hello @Lukas47,

Refer to Evlservo1 User Manual "Figure 6. SERVO_CTRL1 board schematic (2 of 4): regulators" part and Stspin32g4 buck converter application note for more DC supply details.
On the current board design, VM provided through CON1/3 input is necessary.
