Thank you!

Hello!

What is the most appropriate firmware to program a RP2040 Zero board?

https://www.waveshare.com/wiki/RP2040-Zero

Maybe the PIMORONI TINY2040 which also has 2 MB of Flash, or the RASPBERRY PICO firmware?

Is there any difference between them?

Thankfully,
Ernesto.

Hi Davef

Looking at the schematic it seems to me that the connections of the USB connector depend on the resistors R32/R39 and R33/R38

Well, I was finally able to successfully flash the firmware to my ESP32-S2-Saola board. https://docs.espressif.com/projects/esp-idf/en/latest/esp32s2/hw-reference/esp32s2/user-guide-saola-1-v1.2.html Obviously I hadn't understood the function of each USB port, but the instructions aren't very clear ...

Hi! I just bought an ESP32-S2-Saola-1 V1.2 board and I haven't been able to install the Micropython firmware. I downloaded the "Generic_S2" and "ESP32_S2_Wrover" versions and I haven't been able to get either one to work. I tried it first from Thonny and then with ESPTOOL and the result was the same...

Hello! I want to send some data to thinger.io from an ESP8266. Although I have seen that it can be done using HTTP, apparently in this way all the benefits of the platform are not taken advantage of, which is achieved with the incorporation of a library in the code. However, I only find the library ...

Thank you Peter!
