Description:

This module uses 24 high precision A/D converter chip hx711. It is a specially designed for the high precision electronic scale designwith two analog input channelthe internal integration of 128 times the programmable gain amplifier. The input circuit can be configured to provide a bridge type pressure bridge (such as pressureweighing sensor mode)is of high precisionlow cost is an ideal sampling front-end module.

Features:
