I have purchased three TB9051FTG Single Brushed DC Motor Driver Carriers and want to use the VCC pin to power external logic components. However, when the board is powered by 11.5V, VCC is about 0.3V when it should be 5V. Only connections are:
Vin --> 11.5 V
GND --> Battery Negative
ENB --> Battery Negative
Am I correct to assume that VCC should read 5V? Any ideas why three boards read 0.3V instead?
Thank you,
Oliver
