Espressif Systems ESP32-C6-WROOM-1 Multiprotocol Modules

Espressif Systems ESP32-C6-WROOM-1 Multiprotocol Modules are general-purpose Wi-Fi®, IEEE 802.15.4, and BLUETOOTH® LE modules. These multiprotocol modules are built around the ESP32-C6 series of SoCs and 32-bit RISC-V single-core microprocessors featuring up to 8MB flash. The ESP32-C6-WROOM-1 multiprotocol modules feature 23 GPIOs, rich peripherals, and an onboard PCB antenna. These multiprotocol modules integrate a rich set of peripherals, including SPI, parallel IO interface, controller, and on-chip debugs functionality via JTAG and SOC event task matrix.

The ESP32-C6-WROOM-1 multiprotocol modules feature CPU and on-chip memory, Wi­-Fi, integrated components on the module, and Bluetooth. These multiprotocol modules operate at a 3V to 3.6V operating voltage range. The ESP32-C6-WROOM-1 multiprotocol modules are ideal for use in smart home, industrial automation, health care, and consumer electronics applications.
