News on

Maybe you remember when ST Microelectronics and Arduino released a news about Arduino/Genuino board.
The devel board named Arduino STAR OTTO and the main component of board should be STM32F469 microcontroller. The news promised WiFi on-board module, possibility of connecting of display, connector of camera and MEMS microphones.
How the development looks, you can check in this news.
Photogallery of Arduino STAR OTTO.

Whether you design of devices sometime you will need some tools for easier development of something. Maybe you made something what could be helpful for other makers.
Maybe your helpful tool doesn't sell.

Following yesterday?s Raspberry Pi Compute Module 3 launch, we have a new development board turned into system-on-module (SoM) today with PINE64 launching SOPINE A64 SO-DIMM module based on Allwinner A64 processor with 2GB RAM together with SOPINE ?Model A? baseboard.

Officially Raspberry Pi Foundation releases Raspberry Pi Compute Module 3 (unofficially here and here).

As we could expect, the main components are the same like in Raspberry Pi 3.

The processor of CM3 is 10x more powerful than originally CM1...

In today article about Orange Pi Zero I want to show you how to blink of LED, measure the temperature by AD7415 sensor, which communicates through by I2C and at the end we send some data to NRF24L01 through SPI. I have to write you, at the beginning, that NRF24L01 doesn't work, but Orange Pi Zero works fine by analyzer. The codes are written in pythonu.

Maybe you have not ESP32 module, but if you plan to buy it, you should check this tutorial "ESP32 in Arduino IDE for Mac and Debian/Ubuntu".

On this page you find what to do for correct working ESP32 in Arduino IDE.

After these steps you check if it works properly through example program, WiFi scanner, which you load to ESP32.

All steps there:

Espressif released info about a new development board with ESP32.

The board contains of course ESP32 module, 3.2" SPI LCD, external pSRAM memory and VGA camera interface.

ESP32 supports JTAG debuging and so you can use USB debugger. Next, you can develop with micro SD card, the board contains micro SD card slot.

All pins are connected to header.
