ESP32-C6-WROOM-1 is a powerful, general-purpose Wi-Fi, IEEE 802.15.4, and Bluetooth LE module. 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. It features an external SPI flash up to 8 MB. Both ESP32-C6-WROOM-1 comes in two versions: 4 MB flash version and 8 MB flash version.The two versions only vary in flash part number. At the core of the modules is ESP32-C6, a 32-bit RISC-V single-core processor. Features CPU and On-Chip Memory ESP32-C6 embedded, 32-bit RISC-V single-core microprocessor, up to 160 MHz ROM: 320 KB HP SRAM: 512 KB LP SRAM: 16 KB Wi-Fi 1T1R in 2.4 GHz band Operating frequency: 2412 ~ 2484 MHz IEEE 802.11ax-compliant 20 MHz-only non-AP mode MCS0 ~ MCS9 Uplink and downlink OFDMA, especially suitable for simultaneous connections in high-density environments Downlink MU-MIMO (multi-user, multiple input, multiple output) to increase network capacity Beamformee that improves signal quality Channel quality indication (CQI) DCM (dual carrier modulation) to improve link robustness Spatial reuse to maximize parallel transmissions Target wake time (TWT) that optimizes power saving mechanisms Fully compatible with IEEE 802.11b/g/n protocol 20 MHz and 40 MHz bandwidth Data rate up to 150 Mbps Wi-Fi Multimedia (WMM) TX/RX A-MPDU, TX/RX A-MSDU Immediate Block ACK Fragmentation and defragmentation Transmit opportunity (TXOP) Automatic Beacon monitoring (hardware TSF) 4 × virtual Wi-Fi interfaces Simultaneous support for Infrastructure BSS in Station mode, SoftAP mode, Station+ SoftAP mode, and promiscuous mode. Note that when ESP32-C6 scans in Station mode, the SoftAP channel will change along with the Station channel 802.11mc FTM Bluetooth® Bluetooth LE: Bluetooth 5.3 certified Bluetooth mesh High power mode (20 dBm) Speed: 125 Kbps, 500 Kbps, 1 Mbps, 2 Mbps Advertising extensions Multiple advertisement sets Channel selection algorithm #2 LE power control Internal co-existence mechanism between Wi-Fi and Bluetooth to share the same antenna IEEE 802.15.4 Compliant with IEEE 802.15.4-2015 protocol OQPSK PHY in 2.4 GHz band Data rate: 250 Kbps Thread 1.3 Zigbee 3.0 Peripherals GPIO, SPI, parallel IO interface, UART, I2C, I2S, RMT (TX/RX), pulse counter, LED PWM, USB Serial/JTAG controller, MCPWM, SDIO2.0 slave controller, GDMA, TWAI® controller, on-chip debug functionality via JTAG, event task matrix, ADC, temperature sensor, system timer, general-purpose timers, and watchdog timers Integrated Components on Module 40 MHz crystal oscillator SPI flash Antenna Options On-board PCB antenna (ESP32-C6-WROOM-1) External antenna via a connector (ESP32-C6-WROOM-1U) Operating Conditions Operating voltage/Power supply: 3.0 ~ 3.6 V Operating ambient temperature: –40 ~ 85 °C Certification Green certification: RoHS/REACH Test HTOL/HTSL/uHAST/TCT/ESD
