You can now buy BBC micro:bit board for $19

BBC recently distributed micro:bit boards to UK schools to get student interested in electronics and help them learn more about this subject, but so far it was not for sale to the general public, but this has now changed since the British broadcaster now launched the board for 13 GBP (~$19) via Element14/Farnell and others distributors. The board is powered by Nordi Semi nRF51822 SoC with ARM Cortex M0 micro-controller and Bluetooth LE connectivity, features motion sensors, plenty of LEDS, a few buttons, a micro USB connector for power & programming, as well as a header for LiPo batteries. There are various ways to program the board either interpreted languages such as Python or JavScript, or graphical drag and drop programs such as Microsoft Block Editor. All technical details and example projects available on Micro:bit official website. Beside the board only, several kits are being offered included micro:bit Go with […]

Programming ESP8266 Boards with a Smartphone

In recent days, I wrote about low cost MCU boards such as the $2 BluePill, and the One Dollar Board project, but several people commented that while the board themselves are very cheap, it might still be a problem in some developing countries, where access to computers cannot be taken for granted. So person suggested that such initiative would work better in some countries if programming was possible via a smartphone instead. Is that true? According to a 2014/2015 study by Pew Research Center, there is some truth to it, but it varies greatly between countries. For example, 55% of Brazilian adults own a computer at home, while only 24% own a smartphone, but in Kenya only 8% own a computer at home, while 15% own a smartphone. Some devices in the “cellphones but not smartphones” might be feature phones with WiFi and a web browser. Anyway ideally a low […]
