Ergotech Erw300n Driver Access

Below is the standard 24‑pin header layout (viewed from the front of the board).

| Pin | Name | Function | Typical Level | |-----|------|----------|----------------| | 1 | +V_IN | DC supply (+) | 12 V‑48 V | | 2 | GND | Supply ground | 0 V | | 3 | STEP | Step input (TTL) | 0‑5 V | | 4 | DIR | Direction input (TTL) | 0‑5 V | | 5 | EN | Enable (active low) | 0 V = disabled | | 6 | FAULT | Open‑collector fault output | Pull‑up to 5 V | | 7 | TEMP_ALM | Temperature alarm (open‑collector) | Pull‑up to 5 V | | 8 | PWM_IN | PWM speed reference (0‑5 V) | 0‑5 V | | 9 | AN_REF | Analogue current reference (0‑5 V) | 0‑5 V | |10 | UART_TX | UART transmit (to host) | 3.3 V‑5 V | |11 | UART_RX | UART receive (from host) | 3.3 V‑5 V | |12 | NC | – | – | |13 | NC | – | – | |14 | M_A | Phase A output (to motor) | – | |15 | M_B | Phase B output (to motor) | – | |16 | M_C | Phase C output (to motor) | – | |17 | SENSE_A | Current sense A (optional ADC) | 0‑V_REF | |18 | SENSE_B | Current sense B | 0‑V_REF | |19 | SENSE_C | Current sense C | 0‑V_REF | |20 | +5V_OUT | Board logic supply (regulated) | 5 V | |21 | GND | Logic ground | 0 V | |22–24 | NC | – | – |

The three motor phases (M_A, M_B, M_C) are typically connected to a 3‑phase BLDC motor using a 6‑wire cable (U‑V‑W plus three sense wires if the motor provides Hall sensors; the ERW‑300N does not require Hall feedback because it is a sensor‑less driver.)

Typical wiring checklist

   MCU                     ERW‑300N
   ----                     -------
   GND  ------------------- GND
   5V   ------------------- +5V_OUT (optional power‑sense)
   GPIO1 (STEP) ----------- STEP
   GPIO2 (DIR) ------------ DIR
   GPIO3 (EN) ------------- EN   (active‑low)
   GPIO4 (FAULT) ---------- FAULT (open‑collector, pull‑up to 5 V)

Sample Arduino sketch (simplified)

#define STEP_PIN   2
#define DIR_PIN    3
#define EN_PIN     4
#define FAULT_PIN  5
void setup() 
  pinMode(STEP_PIN, OUTPUT);
  pinMode(DIR_PIN, OUTPUT);
  pinMode(EN_PIN, OUTPUT);
  pinMode(FAULT_PIN, INPUT_PULLUP);
digitalWrite(EN_PIN, LOW);   // keep driver disabled during init
  delay(100);
  digitalWrite(EN_PIN, HIGH);  // enable driver
void step(uint32_t steps, bool dir, uint16_t usDelay) 
  digitalWrite(DIR_PIN, dir);
  for (uint32_t i = 0; i < steps; ++i) 
    digitalWrite(STEP_PIN, HIGH);
    delayMicroseconds(usDelay);
    digitalWrite(STEP_PIN, LOW);
    delayMicroseconds(usDelay);
    if (digitalRead(FAULT_PIN) == LOW) 
      Serial.println(F("FAULT!"));
      break;
void loop() 
  step(2000, true, 500);  // 2000 µsteps, clockwise, 500 µs pulse width
  delay(2000);

*The above example assumes 1/4 µstep (200 steps per rev). Adjust `usDelay
