there has not been much of anything on programming this cheap wireless module with the Arduino IDE. Finally, this has changed. After many months of coding, the Arduino IDE supports the ESP8266 module.

It can be used with the online Arduino Cloud platform, as well. You might, however, encounter some issues when migrating your Rev3 sketch ... a Wi-Fi shield and a Bluetooth module -- are required.

If the Arduino toolchain could target this microcontroller, it could be a great development platform for cheap WiFi devices. The Add-On and Standalone Architectures At first glance, this module ...

There's the Arduino Giga R1 Wi-Fi ... sketch, and upload it to your board. Another challenge with the Raspberry Pi is its documentation. It isn't entirely geared towards using sensors and modules.

Connector to add external battery to real-time clock (RTC) inside Renesas MCU (MCU RTC power pad held to 5V rail on Minima) Secondary (wireless) processor: 240MHz 3.3V dual core 32bit Espressif ...
