1.2 Description
ESP32-C6-WROOM-1 and ESP32-C6-WROOM-1U are two powerful, general-purpose Wi-Fi, IEEE 802.15.4,
and Bluetooth LE modules. The rich set of peripherals and high performance make the module an ideal choice
for smart homes, industrial automation, health care, consumer electronics, etc.
ESP32-C6-WROOM-1 comes with a PCB antenna. ESP32-C6-WROOM-1U comes with a connector for an
external antenna. They both feature an external SPI flash up to 8 MB.
Both ESP32-C6-WROOM-1 and ESP32-C6-WROOM-1U come in two versions:
• 4 MB flash version
• 8 MB flash version
The two versions only vary in flash part number. In this datasheet unless otherwise stated, ESP32-C6-WROOM-1
and ESP32-C6-WROOM-1U refer to the variants in 4 MB and 8 MB flash versions.
The series comparison for the two modules is as follows:
