Battery solution Nano 33 iOT

You can either use the 3.3V pin to supply power to the board, or use the Vin pin. By using the VIN pin to power goes through a (step down) voltage regulator, that provides a nice stable 3.3V to the ...

Why does Arduino Nano 33 IoT always choose the weakest WiFi BSSID?

On Nano 33 IoT the WiFi network adapter is NINA esp32 module with Arduino's nina-fw. nina-fw is written with the use of ESP-IDF framework by the esp32 manufacturer Espressif. To connect to an AP the ...

Arduino with LCD Display does not reset/restart/start on connection to power

You've tagged the question with both nano and arduino-nano-33-iot, but I'm guessing between the two you're using the latter, because on Arduinos with native USB (not a plain Arduino Nano) while (!...

Which Arduino for many analogue sensors (and WiFi)?

For short answer: Just use NodeMCU ESP32 or any ESP32 dev board. TLDR; ESP32 is actually a wifi module but has very powerful processor (240MHz max), way more faster than Arduino Uno (atmega328 @16MHz)...

Arduino nano IoT antenna broke

It is still possible to get work. I see the copper pads have been pulled off so you need to use extra amount of solder and hopefully it attaches to the remained copper wire. My case is even worse ...

Arduino nano IoT antenna broke

The problem that I see in the photo is that the pads from the PCB are pulled off and attached to the antenna. So now there is nothing to solder the antenna back to. While it's possible to rework this ...

How can the SAMD21 chip knows when the on-board NINA W102 restarts

I have solved this later I post the question.😂 The solution is using the fact which SPI on the SAMD21 will hang while W102 restarts, so I just set the SAMD21 restart immediately after the program ...

Is it possible to extract the firmware of an Arduino BLE or IoT board wirelessly?

Technically, the firmware can read its own application section, but it won't send it to you wirelessly (or via any interface) if such a feature isn't implemented in that firmware. If you were to ...
