Sipeed M0sense, a small board with Bluetooth

  • 2 min

The Sipeed M0sense is a compact AIoT (AI + IoT) development board based on the Bouffalo Lab BL702 chip.

Obviously, with that name, the Sipeed M0sense positions itself as a low-cost alternative to the Arduino 33 Sense. In fact, the manufacturer’s own documentation makes the comparison.

The Sipeed M0sense features a 32-bit single-core RISC-V processor running at 144MHz. It has 132 KB of SRAM, 192KB of ROM, and 512 KB of flash storage.

The BL702 provides 15 GPIOs, of which five can generate PWM, a 12-bit ADC, and a 10-bit DAC. Regarding connections, we have one SPI port, two UARTs, one I2C port, and one I2S.

The board integrates a 6-axis IMU (accelerometer + gyroscope), a microphone, an RGB LED, and an 8-pin connector for an optional LCD display.

The package is completed with Bluetooth BLE 5.0 for wireless connectivity and IoT applications.

In short, a very complete board, notable for its tiny size, power, the integration of several devices (like the IMU and microphone), and providing Bluetooth wireless connectivity.

We can purchase the Sipeed M0sense for about 5€ without the LCD screen, or for 7€ with a 0.96” screen. Shipping costs of about 5€ will need to be added to this.
