1. Core Processor

  • MAX32660 Microcontroller:
    • Based on the Arm Cortex-M4F core, with an operating speed of 96MHz. It supports floating-point operations and DSP functions, making it suitable for handling moderately complex tasks such as sensor data processing and running simple algorithms.
    • Memory Configuration: It has 256KB of flash memory for storing programs, 96KB of SRAM for runtime data storage, and 16KB of instruction cache to accelerate program execution.

2. Debugging and Programming Tools

  • Integrated Debug Adapter (Based on MAX32625PICO):
    • There is no need for an additional debugger. Programs can be burned and debugged by connecting to a computer via USB.
    • Supports the SWD debug interface (10-pin Cortex debug connector) and a virtual UART console (simulating a serial port through USB for easy communication with a PC).
    • The debug adapter can be removed from the main board (detached after programming to save space) and reinstalled for connection if needed.

3. Peripheral Interfaces and Communication Functions

  • Communication Interfaces:
    • 2 SPI (High-speed serial interfaces for connecting peripherals such as sensors and memories).
    • 2 I2C (Low-speed serial interfaces for connecting low-speed devices like temperature sensors and EEPROMs).
    • 2 UARTs (Serial ports for communicating with other devices or a PC. UART1A is already connected to the virtual serial port of the debug adapter).
  • General-Purpose Input/Output (GPIO):
    • There are a total of 14 GPIO pins. Some pins support multi-function multiplexing (for example, the pins of SPI/I2C/UART can switch functions).

4. User Interaction Components

  • 1 User Button:
    • Connected to GPIO P0.12, it can be used to trigger input signals (such as key interrupts in programs).
  • 1 Red LED:
    • Connected to GPIO P0.13, it is used for status indication (such as program running, error prompting).

5. Power Supply

  • Power Supply Methods:
    • It can be powered by a Micro USB interface or an external power source (1.7V-3.6V). It supports independent power supply from the debug adapter or the main board (the voltage can be selected through jumper JP1).
    • An internal low-dropout regulator (LDO) is integrated. The LDO can also be disabled to connect a more efficient external power module (by connecting an external regulator to the VCORE pin).
  • Power Filtering:
    • Multiple capacitors (1μF, 4.7μF, etc.) are used to stabilize the power supply and reduce interference.

6. Hardware Design and Expandability

  • Compact Size:
    • The main board measures only 0.65 inches × 0.95 inches, and with the debug adapter, the overall size is 0.65 inches × 2.2 inches, making it suitable for embedded scenarios.
  • Interface Compatibility:
    • The dual-row pin header (with a 100mil pitch) is compatible with breadboards and PCB soldering (both through-hole and surface-mount options are available), facilitating the connection of external sensors and modules.
    • Supports the standard Arm debug interface, allowing connection to external debug tools (such as DAPLink).
  • Clock System:
    • It has 3 on-chip oscillators (ranging from 8kHz to 96MHz) and an external 32.768kHz crystal oscillator for the RTC (Real-Time Clock), providing accurate timing.
