Upgrade your 1S Tiny Whoop with the advanced Happymodel CrazyG473 5-in-1 AIO. This all-in-one board is a marvel of integration, packing a Flight Controller, ESC, Receiver, Video Transmitter, and OSD into a single ultralight board. Powered by the modern STM32G473 MCU, it offers superior processing power and more UARTs than older F411 boards, making it the perfect brain for high-performance micro drones.

Next-Gen G473 Processing

Step up from the F411 era. The STM32G473CEU6 processor handles the latest Betaflight features with ease. Combined with a robust ICM42688P Gyro and a massive 16MB Blackbox, this FC allows for precise tuning and detailed flight logging—a rarity in the tiny whoop class.

5-in-1 Integration (1S Powerhouse)

This board is designed for 65mm and 75mm whoops running 1S LiPo/LiHV batteries.

• ESC: 5A continuous (6A peak) running Bluejay firmware (96KHz ready) for smooth DShot operation and RPM filtering.

• Receiver: Built-in Serial ExpressLRS 2.4G (UART connection). Unlike SPI receivers, this allows for easy firmware flashing via Wi-Fi or Betaflight passthrough.

• VTX: Onboard 5.8GHz OpenVTX adjustable up to 400mW. This provides incredible signal penetration for indoor flying.

• OSD: Integrated Analog Betaflight OSD.

Solid Connectivity

The CrazyG473 comes pre-soldered with an A30 battery connector. The A30 is fully compatible with BT2.0 batteries, offering significantly less voltage sag than the old PH2.0 standard. Please note that this board utilizes an SH1.0-4Pin port for USB connection (adapter usually required/included in kits) to save weight and space.

Key Features:

• Powerful MCU: STM32G473 offers 4 UARTs and fast processing.
