MPINO integrates a CPU, digital inputs, relay or transistor outputs, analog inputs, and communication circuitry on a single PCB. This can simplify wiring and installation for equipment with a fixed I/O count.

• Optocoupler-isolated digital inputs
• Relay or transistor outputs depending on the product
• Models supporting voltage/current analog inputs and NTC inputs
• Models supporting PWM, external interrupts, and high-speed counters
• Product-dependent RS-232, RS-485, UART, and I²C communication
• Use Arduino IDE and ILOGICS core built-in functions

For MPINO, use the pinout of the selected product. Even when both names contain 8A8R, S-type and ATmega2560-type products may have different pin numbers and circuitry.

// Example: first input and first relay output of MPINO-8A8R-S
// For other models, use the pin numbers in that product's manual.
const uint8_t inputPin = 0;
const uint8_t relayPin = 32;
 
void setup() {
  pinMode(inputPin, INPUT);
  pinMode(relayPin, OUTPUT);
}
 
void loop() {
  digitalWrite(relayPin, digitalRead(inputPin));
}

1. Have you selected the board matching the actual product in Arduino IDE?
2. Have you distinguished the output types of R and T models?
3. Have you checked the analog input range and reference-voltage settings in the product manual?
4. Have you checked that PWM, interrupts, and high-speed counters do not conflict over the same timer resources?
5. Have you checked the communication terminal electrical specifications and Serial port?
