SDK Overview
The Ai-M6x series modules use the official Bouffalo Lab SDK for secondary development:
BouffaloSDK is the IoT and MCU software development kit provided by Bouffalo Lab. It supports all Bouffalo chip series and is a combination of bl_mcu_sdk and bl_iot_sdk.
The BL616 / BL618 chips used in the Ai-M6x series are fully supported by LHAL (the unified peripheral driver library), covering ADC, DMA, FLASH, GPIO, I2C, I2S, IR, MJPEG, PWM, RTC, SPI, TIMER, UART, USB, and more.
SDK Architecture
The SDK uses a layered structure. The main directories and their roles are:
| Directory | Description |
|---|---|
bsp/ | Board support package: board (clock, pin, memory, and console board-level initialization), common (common board-level peripheral drivers) |
components/ | Components: networking, OS, file system, security, multimedia, wireless protocols, etc. |
drivers/ | Driver layer: lhal (common peripheral drivers for all chip series), soc (chip-specific peripheral drivers), rfparam (RF parameter configuration) |
examples/ | Official example code, ready to build and run |
tools/ | Build, flashing, and development tools |
docs/ | Quick start, API, and demo documentation |
Directory Tree
The SDK directory tree is long, so it is collapsed by default. Click the heading below to expand/collapse it:

Getting Started
- Environment setup: see Ai-M6x Quick Start (Linux) or Windows
- Example code: located in the
examples/directory of the SDK; pick an example and build it directly - More details: refer to the BouffaloSDK documentation
Why Use the Official Bouffalo SDK
The Ai-M6x series recommends using the official Bouffalo SDK (BouffaloSDK) instead of the Ai-Thinker SDK, mainly for the following reasons:
- Maintained by the original manufacturer: BouffaloSDK is maintained directly by Bouffalo Lab, the chip manufacturer, ensuring timely releases and reliable code quality.
- Legacy bugs fixed: Known issues from earlier versions have been fixed by the original manufacturer; switching to the new SDK avoids these problems and improves stability.
- Continuously updated resources: The original SDK keeps updating drivers, examples, and documentation, so switching provides access to the latest development resources.
