ESP32-C6 is a new chip launched by Espressif. I have been following it since its release, and I believe that the ESP32-C6 is now quite mature. It is worth considering purchasing.
The most outstanding feature of the ESP32-C6 is its communication capabilities, integrating 2.4 GHz Wi-Fi 6, BLE 5.3, and 802.15.4 protocols.
On Wi-Fi
ESP32-C6 supports the 2.4 GHz Wi-Fi 6 protocol (802.11ax), backward compatible with 802.11 b/g/n. It supports the 20 MHz channel bandwidth working mode of 802.11ax, as well as 20/40 MHz bandwidth of 802.11b/g/n protocols.
It supports uplink and downlink Orthogonal Frequency Division Multiple Access (OFDMA) access and downlink Multi-User Multiple Input Multiple Output (MU-MIMO) access. It also supports the target wake time (Target Wake Time, TWT) feature of the 802.11ax protocol for better power saving. Although it is only 2.4 GHz Wi-Fi 6, it can be said that besides speed, all other Wi-Fi 6 features are complete.
On Bluetooth
Low Energy Bluetooth (Bluetooth LE): certified by Bluetooth 5.3
Supports Bluetooth mesh
Rates supported: 125 Kbps, 500 Kbps, 1 Mbps, 2 Mbps
Realizes long-distance communication based on Advertising Extensions and Coded PHY.
Wi-Fi and Bluetooth coexist, sharing the same antenna
IEEE 802.15.4 wireless connectivity technology
Compatible with IEEE 802.15.4-2015 protocol
Works in the 2.4 GHz frequency band
Supports OQPSK PHY
Data rate: 250 Kbps
Supports Thread 1.3
Supports Zigbee 3.0
Supports Matter
It can be said that it covers almost all wireless communication technologies in the Internet of Things, except for less common ones like LoRa.
Moreover, it uses the latest technologies and versions, making it very strong in communication, which is also the main focus of the ESP32-C6. With these features, the ESP32-C6 may be very powerful in wireless control; I have seen it control 100 ESP32-C6s simultaneously with very low latency on Bilibili.
Configuration
It features a maximum 160 MHz RISC-V 32-bit processor and a low-power RISC-V 32-bit processor with a maximum of 20 MHz, with 512 KB SRAM and 320 KB ROM, and can connect external Flash. Currently, the ESP32-C6 modules available are:
ESP32-C6-WROOM-1
ESP32-C6-WROOM-1U
ESP32-C6-MINI-1
ESP32-C6-MINI-1U
The four versions include a MINI-1 with only a 4MB Flash version and 22 GPIOs.
The WROOM-1 offers 4MB, 8MB, and 16MB Flash options, with 23 GPIOs.
All use four-wire SPI rates.
The versions with ‘U’ do not have onboard antennas and require external antennas.
Support for SPI, UART, I2C, I2S, RMT, TWAI, PWM, motor control PWM, and SDIO is included, along with an integrated 12-bit ADC and a temperature sensor.
Development boards are also available:
ESP32-C6-DevkitM-1
Equipped with the ESP32-C6-MINI-1 module
ESP32-C6-DevkitC-1
Equipped with the ESP32-C6-WROOM-1 module
The versions and models are similar to the previous ESP32 series.
Price
The chip is priced at 15.
The MINI-1 module is priced at 21.5.
The WROOM-1 module is currently only available in the 4MB Flash version, priced at 22.
The development board ESP32-C6-DevKitM-1 is for sale at 70.
Espressif’s development boards are relatively expensive, but they are cheaper than the ESP32-S3.
Overall, the strongest feature of the ESP32-C6 is its wireless communication capabilities. If you value wireless communication latency and connection quantity for IoT needs, the ESP32-C6 is currently a very worthwhile choice.
However, currently, the ESP32-C6 is not yet compatible with Arduino or MicroPython. If you are not a user of the ESP-IDF development environment,
it is recommended to wait until everything is compatible before proceeding; otherwise, it will be useless once purchased.

Recently, we have created a development board selection website. Although it is not yet perfect, we have already recorded over 400 development boards. If you are interested or have a need, you can check out our selection website. If you have any good suggestions, you can mention them in the group or leave us a message.
The domain name of our website is: findboard.cn
