HX711 module - VCC and no VDD? Answered
I am trying to build the above circuit powered by battery alone. Sparkfun HX711 is expensive and hence I am using Amazon HX711
HX711 module has Operating Voltage: 2.7V to 5VDC and Operating current: <10 mA
Sparkfun HX711 has VCC and VDD. VCC is the analog voltage to power the
load cell. VDD is the digital supply voltage used to set the logic
level. In many cases, you can just short VCC and VDD together. If your
microcontroller uses 3.3V logic however, you'll want to connect VCC to
5V and VDD to 3.3V.
Amazon HX711 has only VCC and no VDD. Therefore, can I connect
LoadCellHX711SF VCC to NodeMCU1 3V3 instead of connecting
LoadCellHX711SF VDD to NodeMCU1 3V3?
Thanks and regards,
