he’s ready to give every Arduino the ability to program another Arduino over an SD card. BootDrive isn’t terribly different from using an Arduino as an ISP, only now AVRdude runs on the ...

one of [Severin]’s SD cards died on him, Instead of trashing the card, he decided to investigate what was actually wrong with the card and ended up recovering most of the data using an Arduino ...

Then, an Arduino board ... modules. The R4 WiFi is also a more sensible choice for more sophisticated multi-sensor projects that may need higher processing power and memory. Although the R4 ...

the new Arduino UNO R4 features the Renesas RA4M1 (Arm Cortex-M4) running at 48MHz, which provides a 3x increase over the UNO R3. In addition to that, SRAM went from 2kB to 32kB, and flash memory ...

Compared with Arduino’s previous-generation chip, the amount of onboard SRAM cache in the Uno R4 has been increased from 2 kilobytes to 32 kilobytes. SRAM is the high-speed memory in which a ...

Arduino is launching new versions of the Uno board powered by a Renesas 32bit microcontroller. The Uno R4 comes in two versions: the basic Uno R4 Minima and the Espressif-equipped Uno R4 WiFi.
