With the continuous development of FPV drones, UAV systems, and electric aircraft, engineers are increasingly looking for ESC solutions with higher integration, better reliability, and easier installation.
To meet this demand, thus Maxkgo has developed a new 4-in-1 ESC solution integrating four electronic speed controllers into one compact board.
What is a 4 in 1 ESC?
A 4-in-1 ESC is an electronic speed controller that integrates the drive circuits for four motors onto a single circuit board. It manages the power supply and speed regulation for all four motors simultaneously and is primarily used in quadcopter FPV drones. Compared to using a separate ESC for each motor, this integrated design saves space and reduces wiring complexity, resulting in a more compact airframe structure. It is typically suitable for standard quadcopter platforms, facilitating the integration of the flight controller and ESC systems during assembly.
What is the difference between a 4-in-1 ESC and independent ESCs?
| Comparison dimensions | 4 in 1 ESCs | independent ESCs |
|---|---|---|
| Structural form | Four-channel driver integrated onto a single PCB. | Each motor has its own dedicated ESC. |
| Installation location | Center of the fuselage, stacked with the flight controller. | Distributed across the four arms |
| Routing complexity | Relatively low; routing is concentrated. | Relatively high; routing is dispersed. |
| Heat dissipation method | Concentrated heat dissipation; highly dependent on airflow. | Distributed heat dissipation allows heat to be released more easily. |
| Impact of single-path failure | ★★★★ | ★★ |
| Typical Applications | Mainstream FPV quadcopter | Large-scale, mission-oriented platform |

The advantages different with others 4 in1 :
1,We use AM32 firmware, which supports real-time parameter tuning, is compatible with multiple protocols (PWM/OneShot/DSHOT), and offers greater flexibility in debugging.
2,We have developed and optimized the hardware structure, which has the advantage of reducing switching losses and improving battery life efficiency, resulting in approximately 5%-8% energy savings compared to traditional firmware.
3,We offer an optional 4-in-1 version with an additional large heatsink, which can quickly and effectively dissipate heat under high voltage (8S) and high current (60~80A), ensuring system stability.
