5v 2 Channel Low Level With Optocoupler Relay Expansion Board Machine Relay Module
Module parameters:
| Size | 50.5mm (length) * 38.5mm (width) * 18.5 (height) |
| Weight | 28g |
| PCB color | black |
| 1.There are 4 fixing screw holes around the board, the hole
diameter is 3.1mm, which is convenient for installation and fixing 2.The relay uses high-quality Songle relay, single pole double throw. One common end, one normally open end, one normally closed end. 3.Optocoupler isolation, good anti-interference. 4.Low level pull-in, high level release. The status indicator light is on when it is engaged, and it is off when it is released. 5.VCC is the system power supply, and JD_VCC is the relay power supply. Just plug in the jumper cap. |
Electrical parameters:
| Supply voltage | 5VDC |
| Current | greater than 100mA |
| Load | 250V 10A AC or 30V 10A DC |
Wiring instructions:
| VCC | system power supply positive |
| GND | system power negative |
| IN1--IN2 | Relay control port |

1. The maximum current is 2.5A.
2. Up to 32 subdivisions are supported.
3. 4-layer PCB board, better heat dissipation performance.
4. The chip has lower internal resistance, lower heat generation and better heat dissipation.
parameter:
Size: 1.5mmX2mm (same as 4988)
Driven current: 2.5A
Subdivision: 1, 1/2, 1/4, 1/8, 1/16, 1/32
Manufacturing process: SMT placement machine manufacturing, non-manual welding, higher yield, more stable performance
Suitable for:
Where the stepper motor needs to be driven.
It is a necessary module for building 3d printer, cnc, engraving machine and so on.
Supported 3D printers include Prusa Mendel, ultimaker, printbot, makerbot, etc.
You can refer to the following Ardu code to directly drive the motor
DRV8825 features the following points:
1. Suitable for driving stepper motor below 8.2V ~ 45V 2.5A;
2. Only simple step and direction control interface;
3. Six different stepping modes: full, half, 1/4, 1/8, 1/16, 1/32;
4. The adjustable potentiometer can adjust the maximum current output to obtain a higher step rate;
5. Automatic current attenuation mode detection / selection;
6. Overheat shutdown circuit, undervoltage lockout, cross current protection;
7. Ground short circuit protection and load short circuit protection
