Sipeed M1s Module is an AIOT module based on BL808 of Bouffalo Lab, it contains 3 cores inside, with WiFi/BT/BLE wireless units, including multiple cpus, audio encoder and decoder, video encoder and decoder and AI hardware accelerator (BLAI-100), suitable for a variety of high performance and low power applications.

Sipeed M1s Module is a powerful core board with BL808 RISC-V as the CPU, and the powerful tri-core heterogeneous architecture can play a role in high-performance computing power.

BL808 mainly includes two subsystems, wireless and multimedia. The wireless subsystem includes a RISC-V 32-bit high-performance CPU, integrated WiFi/BT/BLE wireless subsystem, which can provide a variety of connection and transmission experiences. The multimedia subsystem includes a RISC-V 64-bit ultra-high-performance CPU and integrates video processing modules such as DVP/CSI/ H264/NPU, which can be widely used in various AI fields such as video surveillance/smart speakers. As well as the BLAI-100 (Bouffalo Lab AI engine) NPU for video/audio detection and/or recognition.

M1s Module can efficiently write more applications thanks to the SPI flash chip onboard. There are two antenna connection methods IPEX-I antenna and PCB antenna all can connect to the wireless network more stably. The core plate adopts the stamp hole connection mode to further improve the stability of the connection between the core plate and the bottom plate.

One advantage of the BL808 is that it can support Linux, and the microcontroller does include an MMU, so you would not have to deal with the usual uClinux headaches.
