Arduino UNO R4 Minima

Arduino UNO R4 Minima is the next-gen UNO—now with a 32-bit Renesas RA4M1 (Cortex-M4 @ 48 MHz), USB-C, wider 6–24 V VIN range, and built-in peripherals like a 12-bit DAC, CAN bus (via external transceiver), RTC, HID, and more. It keeps the classic UNO footprint, 5 V logic, and shield ecosystem—perfect for classrooms, labs, and product prototyping in the Philippines.

Next-Gen UNO — 32-bit Power, USB-C & 24 V VIN

  • Faster MCU & more memory: RA4M1 @ 48 MHz with 256 KB Flash and 32 KB SRAM gives headroom for larger sketches.
  • Still 5 V & R3-compatible: works with most Arduino shields, sensors and displays.
  • Robust power: VIN accepts 6–24 V—great for motors, LED strips, and field gear.
  • Extra I/O features: on-board 12-bit DAC, high-res ADC (up to 14-bit), CAN, HID & SWD debugging.
  • Modern port: USB-C for power/programming and cleaner cabling.

What you can build

  • Data loggers & lab tools: precision sensing with high-res ADC + microSD/RTC
  • Audio & UI gadgets: simple synths/tones via the DAC, status OLED/TFT UIs
  • Motor & lighting control: PWM control for drivers, relays, LED strips with 24 V VIN
  • CAN nodes: industrial/automotive experiments using a CAN transceiver module

Pinout & power notes

  • SPI: use the 6-pin ICSP header for maximum shield compatibility.
  • 3.3 V modules: add a level shifter for 3.3 V-only sensors/displays.
  • CAN: requires an external transceiver module between the board and the bus.
  • VIN vs USB-C: for motors/LED loads, power via VIN (6–24 V) with a quality PSU; keep grounds common.

FAQs – Arduino UNO R4 Minima (Philippines)

Is UNO R4 Minima beginner-friendly?
Yes—same UNO form factor, now with a faster 32-bit MCU and USB-C. Works with the Arduino IDE and most UNO-era libraries; low-level AVR code may need changes.
Which cable and power supply do I need?
Use a USB-C data cable for programming. For standalone projects, VIN accepts 6–24 V (use a regulated PSU).
Are my UNO R3 shields compatible?
Yes—R3 layout and 5 V logic are maintained. For SPI shields, use the ICSP header; adjust CS pins if stacking shields.
Does it have Wi-Fi?
No. For built-in wireless, choose UNO R4 WiFi or add an external Wi-Fi/BLE module.
Do you ship nationwide and support school/corporate orders?
Yes. We ship nationwide across the Philippines via trusted couriers and can prepare classroom bundles and bulk quotations on request.
