English summary: Open FPV hardware project for a 10-layer 75A 4-in-1 ESC board. The repository includes Gerber manufacturing files, schematic PDF, PCB previews, and design notes for DSHOT600, high-current routing, and Infineon gate-driver based MOSFET control.
自主设计的 FPV 无人机飞控与 4合1 电调一体板,从原理图到 PCB 布局全程独立完成。
Status: Download the review snapshot and review PROJECT_STATUS.md before manufacturing or powering this design. Hardware review and build reports are welcome through the current ESC review request.
| 参数 | 规格 |
|---|---|
| 类型 | 4合1 电调(四路电调集成于单板) |
| 持续电流 | 75A × 4 |
| 支持协议 | DSHOT600 / DSHOT300 / PWM / Oneshot |
| PCB 层数 | 10 层 |
| MOS 驱动 | 英飞凌(Infineon)栅极驱动 IC |
| 适用电压 | 3S ~ 6S LiPo |
10 层板设计为大电流路径提供了充裕的铜皮截面积与多层并联导流,相比常见的 4 层板:
- 电源层与地层各有多层并联,载流能力大幅提升
- 信号层与功率层完全隔离,消除大电流切换对 PWM 信号的干扰
- 更低的 PCB 走线阻抗,减少高电流下的压降与发热
采用英飞凌(Infineon)专用 MOS 栅极驱动 IC,相比通用驱动方案:
- 更快的栅极充放电速度,降低 MOS 管开关损耗
- 内置死区时间控制,防止上下桥臂直通
- 更强的驱动能力,支持大尺寸低 Rds(on) MOS 管,降低导通损耗
- 工业级可靠性,适应高温、高电流工作环境
支持 DSHOT600 数字电调协议:
- 无需油门校准,数字信号抗干扰能力强
- 双向 DSHOT 支持转速反馈(RPM Telemetry),配合 INAV/Betaflight 实现 RPM 滤波
- 相比 PWM/Oneshot,延迟更低、精度更高
