$5.5 Banana Pi BPI-PicoW-S3 ESP32-S3 board follows Raspberry Pi Pico W form factor

Banana Pi BPI-PicoW-S3 Raspberry Pi Pico W alternative

Banana Pi’s BPI-PicoW-S3 is a development board following the Raspberry Pi Pico W form factor, but based on Espressif System ESP32-S3 dual-core microcontroller offering both WiFi 4 and Bluetooth LE connectivity. The Raspberry Pi SBCs have inspired many designs, but the Raspberry Pi Pico MCU boards less so. So far, I had only seen the WeAct RP2040 board with the same layout except for a USB Type-C port and a 16MB flash. But the Banana Pi BPI-PicoW-S3 provides a direct alternative to the Raspberry Pi Pico W with a more powerful microcontroller, vector instructions for AI acceleration, BLE, and about the same price at $5.5 plus shipping. Let’s see how the BPI-PicoW-S3 specifications compare to the ones of the Raspberry Pi Pico W in the table below. While the power signal (5V, 3.3V, GND) and GPIO numbers are the same on both boards, there are a few variations here and […]

Arduino IDE 2.0 is now officially released

The first stable release of Arduino IDE 2.0 is now out. Based on the Eclipse Theia framework, the new IDE provides a more modern and user-friendly user interface, faster compilation time, and more features we’ll discuss in this post. Arduino initially introduced the Arduino IDE 2.0 beta in March 2021 with a live debugger with breakpoints support, a revamped user interface with features such as autocompletion of variables and functions. After 18 months of debugging with the help of members of the community such as Paul Stoffregen (the maker of the Teensy boards), the Arduino IDE 2.0 is not an experimental software anymore, and it’s the first version you’d see in the download page. The Arduino IDE 2.0 is available for Windows 10 64-bit and newer, Linux X86-64, and macOS 10.14 “Mojave” or newer. If you’ve already installed Arduino 1.x, it will inform you of updates for your installed libraries […]
