ESP32-C3FN4 MS11SF11

Wi-Fi & BLE Combo Module

MS11SF1 module is an Wi-Fi 4 & BLE 5.0 Module based on ESP32-C3FN4. It features an RISC-V 32-bit single-core processor with an operating frequency of up to 160MHz. The MS11SF1 supports development using AT commands, sending AT commands through the serial port to configure Wi-Fi and BLE to achieve the pass-through function. Besides, you can develop your own firmware by using the ESP-IDF development framework.

The MS11SF1 comes with 22 GPIO pins and integrate a rich set of peripherals including UART, SPI, I2C, I2S, ADC, TWAI (compatible with ISO 11898-1 protocol), LED PWM controller, USB (compatible with 2.0 full speed standard), JTAG controller, temperature sensor, RMT (infrared remote control), and etc.
