The BBC has released a new web-based Python editor for the micro:bit board

There are already Python editors such as Thonny, but the BBC thought those were not good enough and released a new web-based Python editor specifically designed for the micro:bit education board targeting 11 to 14 years old pupils. The micro:bit Python editor includes drag and drop code examples, code structure & error highlighting, auto-complete feature, a simulator to test the code before uploading it to the micro:bit board, and a Quick ideas section to help pupils get started with projects. The BBC’s micro:bit Python editor works with both the micro:bit V1 and V2, but note the simulator shows a micro:bit V2, so if you are using the previous generation micro:bit, some code may work on the simulator but not on your micro:bit V2 board. For that reason, the BBC marked the code that only works on a micro:bit V2 with ‘V2’ in the Reference section. While the BCC is a […]

Khadas Edge2 review with Android 12

We’ve already reviewed Khadas Edge2 Pro with Ubuntu 22.04, and I’ve now had time to test the ultra-thin Rockchip RK3588S SBC with Android 12, so I’ll report my experience checking out the features, running some benchmarks, playing videos and games, etc… Flashing Android 12 to Khadas Edge2 board Our board was running Ubuntu 22.04, so in order to enter OOWOW firmware system, I had to keep pressing the function key (middle), then shortly press the reset button, before releasing the function key and entering the OOWOW interface. We can see the Android 11 image from the list we saw last month is gone for good, and a new Android 12 image dated September 20, 2022 is available. I selected that one, and OOWOW downloaded the files and flashed it to the board. Within five minutes, Android 12 was up and running on the board. As somebody who had spent several […]

ESP32 DevKitC V4 IoT development board ships with ESP32-WROOM-DA dual antenna module

The ESP32 DevKitC V4 is now selling with the ESP32-WROOM-DA module with two PCB antennas that was introduced last year in order to offer a longer WiFi range and better reliability. The development kit is exactly the same as the other ESP32 DevKitC V4 models, and the only difference is the dual antenna design. When running a recent version of the Arduino Core for the ESP32 (2.0.3 or greater), the ESP32 will automatically switch to the antenna with the strongest signal in order to deliver the best connectivity possible. ESP32 DevKitC V4 specifications: Wireless module – ESP32-WROOM-DA (PDF datasheet) with SoC – Espressif Systems ESP32-D0WD-V3 dual-core LX6 microprocessor with 520 KB SRAM, 2.4 GHz WiFi 4 and Bluetooth 4.1 connectivity Storage – 4MB SPI flash Two PCB antennas (ANT1 and ANT2) USB – 1x Micro USB port for power, programming, and debugging through USB-to-UART bridge up to 3 Mbps Expansion […]
