Features:1. Using high-quality materials, the quality is guaranteed2. The pre-amplifier is designed with two op amps, and one op amp is used for one , and the effect is much better than that of a single op amp and two s.3. Built-in single power supply to dual power supply chip, so that it has the effect of dual power supply under single power supply4. Use large-capacity filter s with rectifier circuit, which can be used for both AC and DC5. Wide range of applicationsSpecification:Working voltage: AC5-16V or DC6-24V size: 50mm*50mmOverall height of the board: about 23mmR1, R5 are the magnification setting s (the default is about 5 times magnification for delivery, you can change the magnification according to your own needs, the resistance can be selected from 5k-100k, the larger the resistance, the higher the magnification, if you use a plug-in , you can remove the chip by , and solder the plug-in on the pads at both ends of the patch position)Package list:Amplifier board*1Signal line*2
