Quectel FCM242D Module

Quectel FCM242D Module offers a high-performance processor with a frequency up to 160MHz. This module is a cutting-edge MCU Wi-Fi® and BLUETOOTH® module, supporting IEEE 802.11b/g/n protocol and BLE 5.2. The FCM242D module features built-in 288KB RAM and 2MB flash, ensuring efficient performance. This module complies with WPA-PSK, WPA2-PSK, and WPA3-PSK security standards, supporting True Random Number Generator (TRNG), AES-128 encryption algorithm, and secure firmware and flash encryption. The FCM242D module offers an LCC form factor with an ultra-compact package size of 20mm x 18mm x 2.05mm, optimizing size and cost for end products. This module supports the QuecOpen® solution and standard AT commands.

The FCM242D module supports UART and GPIO interfaces by default, as well as SPI, I2C, ADC, and PWM interfaces in the QuecOpen® solution. This module also supports many low-power consumption modes and a keep-alive mechanism. The FCM242D module provides flexibility and versatility for a range of applications, especially in smart homes and industrial IoT scenarios.
