my own list of successful MicroPython products

Since I don't find an official list, I created my list on https://github.com/retsyo/successful-MicroPython-products What is a "[MicroPython](https://www.micropython.org/) product"? I think it must not merely be a development board which supports programming with [MicroPython](https://www.micropython...

Re: Is there some successful MicroPython products?

I don't think it is suitable to call a product as "micropython product" if only micropython can be used during programming. If so, every board( pyboard, esp8266/32, and a long name list) can be called as "micropython products".

Re: module for 1.44 inch TFT LCD with SDI, RS pins?

finally, the driver ST7735 R in st7735.py makes my LCD work During my search, I have met ST7735, ST7735S and ST7735R, which should be similar to each other. One more question, is there ST7735R module for micropython which supplies more functions like adafruit-circuitpython-st7735r does? I am using E...

Re: module for 1.44 inch TFT LCD with SDI, RS pins?

I did not modify the lib
I am confused. My LCD is 128*128, and I did not connect the optional RESET pin of LCD, so what should be the proper initialization?

module for 1.44 inch TFT LCD with SDI, RS pins?

I have gotten a 1.44 inch TFT LCD of 128*128 pixels, which is actually from another product, so there is no specification for it. This LCD has 11 pins, whose names are listed on the PCB. I try to search and find that they are maybe 1. VCC, 2. GND, 3. GND, 4. NC, 5. NC, 6. LED ( for background light)...

I have some experience with normal esp8266 and esp32 board. I can use mu to program for sp8266 and esp32. I have bough...
