Ai-Thinker M62-13-BLIFN4 Wi-Fi 6 BLE 5.3 Module

Ai-Thinker M62-13-BLIFN4 Wi-Fi 6 BLE 5.3 Module

The Ai-Thinker M62-13-BLIFN4 is an onboard Wi-Fi and Bluetooth IoT wireless module based on the Ai-M62-13 platform. It uses Bouffalo Lab’s BL616 chip as the core processor and supports 2.4GHz Wi-Fi 6, Bluetooth Low Energy 5.3, and Thread for compact connected-device designs.

The official Ai-M62-13 specification lists a 32-bit RISC-V CPU with FPU and DSP support, up to 320MHz main frequency, 532KB SRAM, 128KB ROM, 4KB eFuse, 4MB default Flash, and a 20 18 3.2mm SMD-18 package. It also provides an onboard PCB antenna and common embedded interfaces including USB2.0, SDU, SD/MMC, SPI, UART, I2C, I2S, PWM, GPDAC, GPADC, ACOMP, and GPIO.

Technical Specifications

Integration Notes & Hardware Guidance

• Power Supply Use a stable 3.3V rail within the 2.97V to 3.6V range and reserve at least 500mA for wireless peak current.
• Ripple Control Ai-Thinker recommends LDO power where possible; if DC-DC is used, keep ripple within 30mV and reserve dynamic response capacitance.
• Antenna Layout Place the module at the edge of the host PCB or hollow out the host board near the antenna area for better RF performance.
• Antenna Keepout Keep copper, metal parts, batteries, shielding cans, and tall components away from the onboard PCB antenna area.
• Boot Pin Review GPIO2 is used as Bootstrap; confirm its default state and external circuit before production.
• Interface Planning Confirm required USB, UART, SPI, I2C, I2S, PWM, ADC, and GPIO functions before final pin assignment.
• IO Protection Add 10 to 100 series resistors on IO lines where appropriate and reserve ESD protection near exposed terminals.
• Production Handling Treat the module as ESD-sensitive and follow MSL level 3 storage and baking requirements before reflow soldering.
• Firmware Path The Ai-M62 series supports universal AT commands for quick deployment and also supports secondary development workflows.
