Recommended Betaflight settings: Run a 4 kHz PID loop with DShot300 and bidirectional DShot enabled. The gyro remains at 8 kHz. This follows Betaflight's recommendation for F722 controllers and provides more CPU headroom than an 8 kHz PID loop.
GOKU F722 Pro Mini V2 45A 32Bit 128K 20X20 Stack
We don't build flight stacks. This is the one we run in our own ERA 3.5" Mini builds, so it's the one we sell. The ERA Mini takes a 20x20 stack, this GOKU is 20x20, and it drops straight in.
Plenty of headroom for a 3.5": 2-6S input and 45A continuous per motor, far more than a mini ever pulls. Snap-lock sockets let you wire a clean build with almost no soldering, and the solder pads are still there if you'd rather do it your way. At 9.9g it barely touches the weight budget.
The FC runs an STM32F722 at 216MHz with an ICM42688 gyro, enough performance for a clean 3.5" tune at the recommended 4 kHz PID loop. Dual BECs (10V/2A and 5V/2A) keep your VTX and peripherals on clean, separate power. 16MB blackbox if you log. Six UARTs, up to 8 motor outputs, dual 4-in-1 ESC pads if you ever build X8.
The paired GOKU G45M 4-in-1 ESC runs 32-bit AM32, up to 128k PWM and Dshot up to Dshot1200. Built for digital, DJI O4 and O4 Pro included, which is exactly what the ERA Mini O4 kit is built around.
