if you are a betaflight dev and received an assembled board from crteensy
There is a branch with the "as-built" state that you received: https://github.com/crteensy/yolo-chonker/tree/as-built-20230303
It includes a description of minor mistakes and errors, and what paste (high temp, low temp) was used where.
What this is
betaflight developer FC for the H735
The layout has 6 layers, and the decoupling is designed for oshpark's 6-layer stackup (see oshpark_6L_stackup.png)
- Format: 30x30 hole distance
- Battery voltage range: 2-6S
- 5V DCDC: LMR33620CRNXT
- 3V3: TPS62824
- Separate DCDC for HD out; LMR33620CRNXT set for 10V or 5V, configured with a solder jumper
- MCU: STM32H735
- peripherals that can be connected to the MCU with solder jumpers:
- IMU: ICM-20602 and BMI270; dual gyro is possible
- Flash: S25FL064L
- Baro: DPS310
- LEDs:
- voltage rails LEDs: HD DCDC (5/10 V), 5V, 3V3
- two standard LEDs for the FC
- WS2812B including an output pad to attach more
- battery voltage sensing
- SWD pads
- no analog OSD
- no HD connector
