1 Introduction

Relay
  • The Matrix-Relay module is a SPDT relay which is an electrically operated switch. Relays are used where it is necessary to control a circuit by a low-power signal. In a electric system it is used to protect electrical circuits from overload or faults.

2 Features

  • 1 Form C
  • 5V supply voltage, GPIO signal: 3.3/5V
  • Current on-contact up to 10A
  • LED indicator
  • 2.54 mm spacing pin
  • PCB dimension (mm): 24 x 48

继电器PCB

  • Pin Description:
Pin Description
S GPIO
V Supply Voltage 5V
G Ground

3 Basic Device Operation

This is an SPDT relay. Its supply voltage is 5V and current on-contact is up to 10A. It can drive AC or DC high power loads. NO is Normally Open. NC is Normally Closed. COM is Common. When writing high to pin S NO will be open and NC will be closed.


4 Applications

G Pin30

5 Compile & Run Test Program

Boot your ARM board with Debian and copy the matrix code: 

$ apt-get update && apt-get install git
$ git clone https://github.com/friendlyarm/matrix.git

If your cloning is done successfully a "matrix" directory will be generated.

Compile and install Matrix: 

$ cd matrix
$ make && make install

Run test program: 

$ matrix-gpio_out

Note: this module is not plug and play therefore before running the module please make sure it is connected to an ARM board.
Here is what you should observe:

1: gpio status change
2: gpio status change
3: gpio status change
4: gpio status change
5: gpio status change

6 Code Sample

This Matrix code sample can work with all the ARM boards mentioned in this module's wiki. The name of this code sample is "matrix-gpio_out". Here is its source code: 

int main(int argc, char ** argv) 
{
    int pin = GPIO_PIN(7); 
    int i, value, board;
    int ret = -1;
 
    if ((board = boardInit()) < 0) {
        printf("Fail to init board\n");
        return -1;
    }
    if (board == BOARD_NANOPI_T2)
        pin = GPIO_PIN(15);
 
    if (argc == 2)
        pin = GPIO_PIN(atoi(argv[1]));
    if ((ret = exportGPIOPin(pin)) == -1) {   
        printf("exportGPIOPin(%d) failed\n", pin);
    }
    if ((ret = setGPIODirection(pin, GPIO_OUT)) == -1) {
        printf("setGPIODirection(%d) failed\n", pin);
    }
    for (i = 0; i < STATUS_CHANGE_TIMES; i++) {
        if (i % 2) {
            value = GPIO_HIGH;
        } else {
            value = GPIO_LOW;
        }
        if ((ret = setGPIOValue(pin, value)) > 0) {
            printf("%d: GPIO_PIN(%d) value is %d\n", i+1, pin, value);
        } else {
            printf("setGPIOValue(%d) failed\n", pin);
        }
        sleep(1);
    }
    unexportGPIOPin(pin);
    return 0;
}
