Nuvoton Expertise has grow to be the newest to undertake the traditional Arduino UNO kind issue, asserting the NuMaker-UNO-M4 — a well-recognized footprint for a improvement board constructed across the firm’s NuMicro M467SJHAN Arm Cortex-M4 microcontroller.
“The NuMaker-UNO-M4 improvement board […] continues the traditional [Arduino UNO] design with industrial-grade requirements, providing each ease of use {and professional} efficiency,” the corporate claims of its creation. “The event board is absolutely suitable with Arduino [UNO] pinout and moreover integrates important industrial communication interfaces: Ethernet, RS485, CAN bus, and an SD card interface. It is appropriate for numerous utility situations reminiscent of good transportation, good healthcare, good business, and good houses.”

Arduino’s unique UNO improvement board — full with uncommon spacing between segments of its 0.1″ feminine pin headers — was its first to make the transfer to the Microchip ATmega328P microcontroller, the place it stayed for some appreciable time earlier than the Arduino UNO R4 Minima and WiFi jumped to the Renesas RA4M1. Nuvoton’s NuMaker, then, has extra in frequent with these fashionable UNOs than the unique: the NuMicro M467SJHAN chip at its coronary heart is predicated on the identical Arm Cortex-M4 core as Renesas’ microcontroller.
The NuMicro M467SJHAN encompasses a single 32-bit Arm Cortex-M4 core working at 200MHz, a single-precision {hardware} floating-point unit (FPU), digital sign processor (DSP), a nested vectored interrupt controller (NVIC), and a reminiscence safety unit, together with 512kB of static RAM (SRAM) and 1MB of flash reminiscence. There are 12-bit analog to digital and digital to analog converters (ADCs and DACs), 4 comparators, 24-channel 16-bit pulse-width modulation (PWM), 4 32-bit timers, cryptographic acceleration, USB 2.0 Excessive Velocity and Full Velocity On-The-Go (OTG) help, an Ethernet MAC, and peripherals together with quad-SPI, I2S, LPUART, I2C, CAN FD, KPI, USCI, PSIO, and ISO7816, plus SDHC help and an exterior bus interface.

On the NuMaker-UNO-M4, these options are uncovered on Arduino UNO-format feminine pin headers plus extra connectors the place essential — together with a devoted header so as to add a microSD card slot for storage growth. There is a USB Kind-C connector that can be utilized for knowledge and energy — supporting programming the microcontroller straight from the Arduino IDE utilizing Nuvoton’s core definition and the Nu-Hyperlink USB driver — with a separate barrel-jack connector supporting 8–18VDC energy provides. All instructed, it is a a lot nearer match to the normal Arduino UNO board design than the corporate’s unique NuMaker-UNO — a noticeably bigger design with a side-mounted barrel-jack connector.
Extra info on the NuMaker-UNO-M4 is accessible on the Nuvoton web site; the corporate has begun promoting the board for $33.14, although on the time of writing it was exhibiting as out of inventory.
