if you are a betaflight dev and received an assembled board from crteensy

It includes a description of minor mistakes and errors, and what paste (high temp, low temp) was used where.

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
