Hellobox B1 satellite finder teardown

It is a very simple device for about $15. The main SoC is GX6605S. There is some limited info about this chip on C-SKY page and some technical docs at their tools repo. It communicates with a Bluetooth module TLSR8266 using UART. There is also 4MB SPI flash holding the whole bootloader called GxLoader, Linux kernel and filesystem with the main app. The last important chip is RDA5815M which handles the RF to I/Q conversion. In the future I plan to add an USB-to-Ethernet adapter and repurpose it as an cheap opensource SAT>IP server.
