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.
