CZ.NIC which is known thank to popular and safe Turris Omnia router, introduced a new modular router which is called Turris MOX.

MOX is modular and open-source router where you can just buy only modules which you need.

Saleae, the manufacturer of logic analyzers, released a new beta version of PC software for showing of data waveforms.

The big advantage of this program is real-time showing of data - from digital inputs. In case that your logic analyzer includes analog inputs, the Saleae software shows also this analog waveform.

Andreas Spiess shared video on youtube where he compared ESP battery powered development boards.
If you check the video, you will find answers which you need during your choosing of board.
- Does the board use a shielded module or just a chip soldered on the PCB?
- How many pins are broken out to pin headers?
- Does the board come with an antenna connector for an external antenna?
- Is the board breadboard friendly?
- How clear is the pin labeling?
- Does the board have an additional ?flash? button?
- Is a battery switch available?
- Which battery connector do you need?
- Does the board crash if you disconnect USB?
- What type of voltage regulator and LiPo management chips are used?
- How much current does the board consume?

I'm sure that you encountered with the situation when your code or part of your code didn't work as you wanted - operation with a few pointers, logic operations, conditions, parsing of value from long array etc.

If you have modern microcontrollers and development board which supports debugger (e.g. STM32 and Nucleo, Discovery) you can easily step (debug) your code in debugger.
If you don't have debugger, how do you follow values, variables? Are you using UART? Or LCD?
