BL606P

RISC-V Wi-Fi and Bluetooth LE MCU used in low-cost wireless modules and embedded IoT boards.

China-madeBouffalo LabActiveModerate

Best For

Maker and embedded projects needing Wi-Fi 4 + BLE connectivity with RISC-V and Wireless module.

Avoid If

You need a fully validated production BOM today; verify module availability, SDK maturity, and English documentation first.

Quick Decision Notes

BL606P is indexed as a wifi mcus part from Bouffalo Lab. ChipScout tracks it by practical maker-facing dimensions: interfaces, library readiness, estimated price, field-level sources, and whether the page is strong enough for selection rather than only lookup.

Pinout Table

VCC3.3VPower the module from a rail that matches the breakout board, not just the bare IC.
GNDCommon groundConnect ground between the controller, sensor/module, and external power supply.
SDAMCU I2C dataUse pull-ups appropriate for the board voltage; many modules already include them.
SCLMCU I2C clockKeep wiring short for breadboard prototypes and lower bus speed if unstable.
SCKMCU SPI clockShare with other SPI devices when chip select lines are separate.
MOSIMCU SPI data outRequired for most displays, radios, and writable devices.
MISOMCU SPI data inMay be optional for write-only displays.
CSAny free GPIOUse one chip-select pin per SPI peripheral.
TXMCU RXCross TX to RX between the module and controller.
RXMCU TXCheck whether the module is 3.3V logic before connecting to 5V boards.

Pinout is not yet source-verified. Use the table as an integration checklist, then confirm exact pins against the module vendor page before wiring hardware.

Common Wiring

VCC

Power the module from a rail that matches the breakout board, not just the bare IC.

GND

Connect ground between the controller, sensor/module, and external power supply.

SDA

Use pull-ups appropriate for the board voltage; many modules already include them.

SCL

Keep wiring short for breadboard prototypes and lower bus speed if unstable.

Arduino Example

Arduino support is not verified for this record yet. Add a library resource in the admin panel once a maintained driver or vendor SDK example is confirmed.

MicroPython Example

MicroPython support is pending. Treat community scripts as prototypes until a maintained driver is linked and tested on a known development board.

Recommended Development Boards

BL606P official dev board

Best first choice when available because USB, regulator, boot buttons, and pin labels match vendor docs.

ESP32-S3 DevKitC

Useful baseline for USB, I2C, SPI, UART, and Arduino/MicroPython smoke tests.

Breadboard-friendly module carrier

Use when validating power draw, pin exposure, and module variant differences.
