## Description

DFRduino M0 is the first 32-bit Arduino microcontroller based on ARM Cortex-M0 core that supports 5V logic. If you use a standard UNO-compatible microcontroller in a project, do you ever find that GPIO and processing performance is underwhelming? Upgrading to a Mega style microcontroller is too expensive, and Arduino ZERO/M0 doesn’t support 5V logic. These problems are solved with the DFRduino M0. The DFRduino M0 uses a Nuvoton high-performance 32-bit microcontroller as the processing core with integrated ARM Cortex M0 architecture, supports 5V logic, includes a USB port and two hardware serial ports with 31 digital pins (partial multiplexing) and 6 analog pins. It is compatible with Arduino Leonardo pin mappings and has more I/O resources and more powerful processing capacity. In addition,, the DFRduino M0 extended features an IIS interface to support playback of wav files. With a professional IIS chip, you can enjoy HiFi audio experience. Note: Due to the different control chip, DFRduino M0 is totally different to the official Arduino M0 microcontroller. Please see the wiki for more information.   SPECIFICATION     Microcontrollers: Nuvoton NUC123ZD4AN0 (Cortex M0) Clock Speed: 72MHz Operating Voltage: 5V Recommended Input Voltage: 7-12V Limit input voltage: 6-20V Digital I/O Pins: 31 Analog input Pins: 6 External Interrupt: 4 SRAM: 20K Flash: 68K (12 KB of which is allocated to bootloader, 55K used by the user code area, 1K used by EEPROM) EEPROM: 1K SPI: 1 port (D14, D15, D16) IIC / I2C: 1 port (D2, D3) USB serial port: 1 (Serial) Physical serial port: 2 (Serial1, Serial2) Serial1 0 (Rx1) and 1 (Tx1) Serial2 24 (Rx2) and 25 (Tx2) Xbee interface: 1 (Serial1) Size: 68 x 53 mm/ 2.68 x 2.09” Weight: 30g     DOCUMENTS   Product wiki More Documents
