1. The BLDC drive section features 3 IR2104 gate drivers and 6 NMOS transistors, with control logic compatible with the official Simple FOC L6234PD solution; 2. Main control module: ESP32-WROOM-32E, 4MB Flash dual-core MCU with Wi-Fi & Bluetooth capability; 3. Integrated 2 INA240A2 high-precision current sensors for phase current measurement; inline sampling resistance for phases A and B is 10m (achieved using two 20m resistors in parallel); 4. Supports magnetic sensor encoders such as AS5600 and AS5047P; 5. Includes an onboard ESP32 firmware programming port for secondary development; 6. Features an onboard reset button and power indicator; 7. Power supply input: DC 12-28V; 8. Maximum continuous output current: 20A; Interface Details: 1. VCC, GND: DC 12-28V power input; 2. ESP32-WROOM-32E: 4MB Flash dual-core MCU with Wi-Fi & Bluetooth module; 3. ESP32 reset button; 4. IR2104 half-bridge gate driver: - SD# Enable pin: High level active; when SD# is high, HO and LO outputs are controlled by IN signal; - HO and LO outputs are disabled when SD# is low; - IN control input: when SD# is enabled, IN high results in HO high and LO low; IN low results in HO low and LO high; 5. 30V/30A N-channel MOSFETs: Recommended operating range within 28V/20A due to current sensing limits; 6. INA240A2 high-precision current sensing amplifier for measuring phase A and B inline currents; 7. Phase A and B current sensing resistors: 10m (using two 20m resistors in parallel), matching Simple FOC V2.0.4 design; maximum per-phase current 20A; 8. C: Brushless motor connection interface; 9. IO expansion port: Supports connecting I2C and SPI interface magnetic encoders (e.g., AS5600, AS5047P); Color: Black Material: PCB Package Contents: 1 x ESP32 20A Brushless Motor Driver Board Note: Lighting effects and display settings may cause slight variations between the product color in images and actual physical item. Measurement tolerance: 13 cm.
