Product Name : 8CH IIC I2C Logic Level Converter Bi-Directional Module & DC-DC 5V to 3.3V Setp-dowm Buck AMS1117 Module For_Arduino Breadboard
No matter how many pieces you buy the board, you only need to pay 1 piece Shipping costs
Module No.: TB371
Packing list:
1 pcs 2 in 1 5V to 3.3V DC-DC Buck Module & 8 channels Logic level converter;
Description:
1 On board DC 5V to 3.3V DC-DC Step-Down Power Supply Buck Module,IC AMS1117-3.3;
2 On board 8 channels 5V to 3.3V(also 3.3V to 5V) Logic level converter,base Limiting resistor;
3 Arduino Breadboard friendly;
4 PCB size:25* 15mm
Level conversion principle:
Between 5V and 3.3V level plus 470 ohm current limiting resistor, to avoid being burned of 3.3V port.
So, when the LOW side no-load, HIGH side plus 5V level,LOW side test is still at 5V level,vice versa.
This is a normal phenomenon, not the level conversion function does not work.
