Whirlybird/RS41
Expanding ESP32-S3 capabilities with RS41 Radiosonde integration utilizing UART communications. One proof of concept TEST prototype has been constructed using point to soldered connections. The current BETA is being constructed using a modified 10 conductor 1mm spaced flat ribbon cable and 2x5 2mm IDC connector. This makes for a "plug-able" adapter between the sonde and main PCB. The position and connections utilized are an interim test of developing a custom M.2 Key E form factor adapter.
TEST utilizes the regulated 3v3 power directly to the sondes MCU and a GPIO expander port that enables a sink to ground for reset. BETA is experimenting with supplying 4v7 to the battery connection so the sonde can power itself from integrated voltage regulators.
