The UNO R4 Minima features a microcontroller based on the Renesas RA4M1 (Arm\u00ae Cortex\u00ae-M4) with an operating voltage of 5 V. It has 14 digital I\/O, 6 analog inputs with up to the 14-bit resolution, a clock speed of 48 MHz, and 32 kB SRAM, 256 kB flash memory & 8 kB of EEPROM.<\/p>\n
It features a DAC for audio projects, RTC for accurate time tracking and HID for emulating a keyboard\/mouse. The barrel jack plug (VIN) supports voltages at up to 24V, making it compatible with common higher voltage adapters.<\/p>\n<\/div>\n

<\/p>\n
<\/p>\n
Keep track of time & date and set alarms with the built-in RTC.<\/p>\n
<\/p>\n
Use the onboard 12-bit DAC to build sophisticated audio projects.<\/p>\n
<\/p>\n
Build game controllers by emulating a mouse\/keyboard.<\/p>\n
<\/p>\n
<\/p>\n
Connect your board to other CAN devices. This requires an external transceiver.<\/p>\n
<\/p>\n
This board supports analogue read resolutions at up to 14-bit.<\/p>\n
