The Arduino Uno-compatible board has an MCS-51 (often called 8051 instead) ... which has similar dimensions to USB-B connector. We need to have 4 pins merely. GND, TXD, RXD, RESET.

The first step I took in building this was to build a 3D model in Rhino. I based it on the Arduino Uno dimensions, and then started creating the parts based upon my real-world materials and scale.

Arduino has announced the new UNO R4 board family for prototyping and learning. The new models feature a faster microcontroller, a USB-C connector, improved power, Wi-Fi and Bluetooth LE, and more.

The Arduino UNO R4 boasts a 3x performance increase over the UNO R3 and , in addition, SRAM has been upgraded from 2kB to 32kB, and flash memory from 32kB to 256kB to support more complex projects.

The official Arduino team has this week revealed more details about the new Arduino UNO R4 development Board which will be officially launching in a few months time during May 2023. The ...

As electronic devices got more complicated in the past few decades, it became increasingly difficult and expensive to tinker with hardware. The 1970s garage engineers who built their own computers ...
