Ai-Thinker M64P-32S Development Board

Overview

Ai-M64P-32S is a Wi-Fi 6 + BLE5.3 module developed by Shenzhen Ai-Thinker Technology Co., Ltd. The module is equipped with the BL616CL chip as the core processor, supports Wi-Fi 802.11b/g/n/ax protocol and BLE protocol, and supports Thread protocol. The BL616CL system includes a low-power, high-performance 32-bit RISC-V CPU with floating-point unit, DSP unit (P extension), 16KB ICache, 8KB DCache, and 388KB of memory.

Hardware

Ai-M64P-32S-Kit provides the following hardware components:

  • Ai-M64P-32S module with BL616CL, and two internal buck regulators controlled by GPIO2 and GPIO3

  • Five total LEDs:

    • RGB LEDs on GPIO14, 15, and 16

    • Warm White LED on GPIO28

    • Cold White LED on GPIO27

  • Two Buttons:

    • Reset Button (EN)

    • Boot Select Button (BOOT)

  • CH340C USB to UART adapter.

System Clock

The M64P (BL616CL) Development Board is configured to run at maximum speed (320MHz).

Serial Port

The ai_m64p_32s_kit board uses UART0 as default serial port. It is connected to USB Serial converter and port is used for both program and console.

Programming and Debugging

Samples

  1. Build the Zephyr kernel and the Hello World sample application:

    # From the root of the zephyr repository
west build -b ai_m64p_32s_kit samples/hello_world
west flash

  2. Run your favorite terminal program to listen for output. Under Linux the terminal should be /dev/ttyUSB0. For example:

    $ screen /dev/ttyUSB0 115200

    Connection should be configured as follows:

    • Speed: 115200

    • Data: 8 bits

    • Parity: None

    • Stop bits: 1

    Then, press and release RST button
