Arduino UNO R4 Minima and WiFi Now Available!<\/h2>\n

In the world of modern electronics, few things are as timeless and noteworthy as the\u00a0Arduino<\/a>\u00a0Uno \u200eRev3 with its socketed\u00a0Atmega328 DIP chip<\/a>. This board helped launch the maker movement we know \u200etoday by tearing down barriers to DIY electronics projects when it was first released in 2010 \u2013 you\u2019d be \u200ehard-pressed to find an embedded programmer today that hasn\u2019t wielded this board at some time \u200eduring their tenure. Therefore, the launch of a new UNO board is certainly something to make one \u200estand and take notice!<\/p>\n

Building upon over a decade of technological developments, Arduino has now released not one but \u200etwo new boards to continue this legacy: the Arduino UNO R4 Minima and UNO R4 WiFi!<\/p>\n

In the world of modern electronics, few things are as timeless and noteworthy as the\u00a0Arduino<\/a>\u00a0Uno \u200eRev3 with its socketed\u00a0Atmega328 DIP chip<\/a>. This board helped launch the maker movement we know \u200etoday by tearing down barriers to DIY electronics projects when it was first released in 2010 \u2013 you\u2019d be \u200ehard-pressed to find an embedded programmer today that hasn\u2019t wielded this board at some time \u200eduring their tenure. Therefore, the launch of a new UNO board is certainly something to make one \u200estand and take notice!<\/p>\n

Building upon over a decade of technological developments, Arduino has now released not one but \u200etwo new boards to continue this legacy: the Arduino UNO R4 Minima and UNO R4 WiFi!<\/p>\n

\"Arduino<\/p>\n

The\u00a0Arduino UNO R4 Minima<\/a>\u00a0maintains the well-established\u00a0UNO R3<\/a>\u00a0form factor and pinout, along \u200ewith 5V logic, making it directly compatible with all your favorite Arduino Shields. However, this new \u200eUNO is packing much more horsepower than the classic UNO. Fitted with a 48MHz 32-bit Cortex\u00ae M4 \u200eRenesas microcontroller featuring 256kB flash memory and 32kB RAM, this board is well suited for the \u200emost demanding of embedded applications. Additionally, the R4 features a modern USB-C port for \u200eprogramming and power that even allows the new UNO to act natively as an HID keyboard or mouse \u200eand an onboard SWD connector that supports advanced debugging capabilities. Finally, the UNO R4 \u200enow supports input voltages ranging from 6-24VDC on the VIN pin or via the DC barrel jack.<\/p>\n

\"Arduino<\/p>\n

The\u00a0Arduino UNO R4 WiFi<\/a>\u00a0sports all the features of the Minima, save for the SWD port, which is \u200ereplaced by an error-catching mechanism that detects runtime crashes and provides detailed \u200eexplanations and hints about the code line causing the crash, so you are not left without debugging \u200esupport. In addition to the Minima\u2019s feature set, the WiFi board sports an ESP32-S3 module, which \u200eprovides the namesake WiFi functionality as well as Bluetooth connectivity. Further expanding the \u200econnectivity is a\u00a0Qwiic<\/a>\u00a0connector for a solder-free, daisy-chainable interface with I2C expansion boards. \u200eSimilar to the recent\u00a0Arduino Giga R1 WiFi<\/a>, the UNO R4 WiFi also features an onboard RTC that can be \u200epowered independently of the remainder of the board, allowing for timekeeping during deep sleep or \u200ecomplete power-down states. And finally, you will notice the board features a user-controlled 12×8 \u200ered LED matrix, often eliminating the need for an additional display shield.<\/p>\n

\"Arduino<\/p>\n

Overall, the UNO R4 Minima and WiFi greatly expand the functionality and features of the classic UNO \u200eR3, presenting a new horizon for makers. However, for those closely tied to the UNO R3, there are no \u200eplans to discontinue the board, so compare all your options for an Arduino UNO below, and choose the \u200eboard best suited to your next project.<\/p>\n
