DA16600MOD-AAC4WA32

DA16600MOD-AAC4WA32 is a pre-certified wireless module from Dialog Semiconductor (Renesas) built around the DA16600 BLE SoC. It combines the radio, RF front-end, embedded flash/RAM, and a small host MCU to simplify BLE-enabled IoT product development. The module exposes common interfaces such as UART, SPI, I2C, GPIOs, and PWM, plus an antenna connection, so a party MCU can handle application logic while the module handles wireless.
The “-AAC4WA32” suffix denotes packaging/variant options and firmware configuration; exact pinout, voltage range, memory size, and supported interfaces are documented in the datasheet and product brief. This module is typically pre-certified for regulatory approvals (e.g., FCC/CE), reducing certification effort for end products. Development usually uses Dialog’s SDK and toolchain.
Common use cases: sensors, beacons, wearables, and other low-power IoT nodes requiring BLE connectivity with minimal radio/Tx/Rx integration.
