Hi all,

In recent weeks we ordered and received almost 90% of the parts needed to assemble prototypes of uLogger.  This was quite an endeavor since the electronic industry recently (almost 2 years now) struggling with the long production process of uC and most of the big distributors are lacking parts or they disappear quickly from shelves.

Initially, uLogger was supposed to have a different design with a different STM32 but we were waiting and waiting for this selected uC to again appear on shelves. We decided to change the design and adjust the firmware to complete this project.

Here is it.

We still lack the ESP32 wifi module (it can be seen in 2nd picture) but the rest of the components are already mounted.

The next step will be adjusting already written firmware for the new STM32 uC and tests, tests, and tests.

That's it for now. Have a nice DIY time for yourself.
Best regards,

Rafal
