FAN2B header does not exist #11

Open x2ocoder opened 1 year ago

x2ocoder commented 1 year ago

In the documentation FAN2B is documented with pins 24V and PD4.

PD4 does not exist in H616 Chip FAN2B Header it on PCB

Is it FAN3B?

billru05 commented 1 year ago

I am also seeing confusion, On the STM32G0B1RCT6 pinout its showing Fan1_PWM PD2 Fan2_PWM PD3 Fan3_PWM PD4 **Where is Fan0 Then on the board pinout its showing Fan0_PWM PD2 Fan1_PWM PD2 Fan2A_PWM PD4 Fan2B_PWM PD4 So, the confusion is the Schematic pinout on the STM32G0B1RCT6 it shows Fan3_PWM PD4 on the board pinout it shows Fan2A & Fan2A on PD4, *****need clarification on where is Fan0 and is Fan 2A & 2B both share PD4

PD4 is not on the H616. It is on the MCU.

There is a fan output that connects to the CB1 but that is a different pin entirely.

FAN2A/FAN3B share the same PD4 on MCU
