Re: New ESP32 development board DMtech DEV01 with NB-IoT interface

The board exists in its first iteration which works quite well but needs some slight modifications. It would also be good to perform antenna impedance matching circuit tuning before mass production. Anyway NB-IoT interface works well with default values as well. The values are sourced from antenna d...

Re: ESP32 PIN.OUT voltage

The pin cannot provide such current directly. I suggest to use high-side P-channel MOSFET to control the load (pump).

I usually use DMP2066 for switching of external components.

Re: ESP32 PIN.OUT voltage

What do you mean by "pump" and what is its maximum input current?

Re: MicroPython version 1.10 released

Good work!

Could you please elaborate on how PPPoS functionality of ESP32 port can be used to add support for a specific cellular modem?

Re: Crowdfunding of ESP32 port development

I am aware of the port and Loboris really did a great job. However I would prefer to put my money into mainline which is maintained and updated regularly and by multiple contributors.

Re: Crowdfunding of ESP32 port development

I am sure that Pyboard D will be superior to ESP32 boards in many aspects. On the other hand due to pricing and availability it will probably be suitable for special applications and not for mass market IoT products for which it would be an overkill, technically speaking. In my opinion ESP32-WROOM/E...

Re: High level GUI lib/framework

There is an effort going to port LittlevGL to Micropython. Open issue: https://github.com/littlevgl/lvgl/issues/557 Micropython fork (work on progresss): https://github.com/kisvegabor/lv_mpy Very interesting project. Is my understanding correct that for now it is possible to test only with Unix port?
