1 year ago @Hedda Thanks for the suggestions.
I like the idea of having WiFi 6 and Zigbee+Matter+Thread without adding much cost. I'll try to get my hands on some ESP32-C6-MINI modules when it's released to try it out.

1 year ago @meatpiHQ Nice! ESP32-C6-MINI-1 module as well as the 8MB SPI Flash version of ESP32-C6-WROOM-1-N4 Engineering Module look to be sold out everywhere, but FYI, can still buy the smaller 4MB SPI Flash version of ESP32-C6-WROOM-1-N4 Engineering Module from a couple of places like Adafruit and Mouser for around $3(US) per module if you act very fast:
https://www.adafruit.com/product/5670
You can otherwise order "MOQ 3250" in bulk directly from Espressif or possibly even get free samples if you tell them about your products/projects:
https://www.espressif.com/en/contact-us/sales-questions
ESPRESSIF Official Store on Aliextress as well as Digi-Key is completely out of stock of all ESP32-C6 modules and devkit boards.
https://www.aliexpress.com/store/1100220184
But there look to be several unofficial resellers that might have ESP32-C6-MINI-1 and/or ESP32-C6-WROOM-1 module in stock:

PS: ESP32-C6-MINI-1 will be smallest ESP32-C6 based module but as a downside it might only come in a 4MB SPI Flash variant.

1 year ago One important addition of ESP-C6 is WiFI 6 Target wakeup time (TWT). It would allow the device to stay connected to the WiFI after waking up from sleep, reducing power usage further.

1 year ago I'm keen to try the C6, I wish it had more IOs and a second core though.
I've already ordered C6-mini modules it seems to be somewhat pin compatible with the C3-mini, I should be able to swap the module and try it out.

1 year ago FYI, 01Space is sell a tiny ESP32-C6 IoT dev board based on ESP32-C6-WROOM-1 wireless module with two 10-pin headers + USB-C for power:
https://www.aliexpress.us/item/3256805225446433.html
Note! Again, ESP32-C6 Arduino support will require ESP IDF 5.1 framework which is still under development and not yet released:

1 year ago @Hedda I've already received the C6-Mini modules, but I don't have time to work on the firmware now. If you like I can send a modified board if you want to try it out?

1 year ago FYI, Espressif ESP-IDF v5.1 with ESP32-C6 (and ESP32-H2) has now been released and supports most of its functions upstream:
https://github.com/espressif/esp-idf/releases/tag/v5.1
https://github.com/espressif/esp-idf/issues/10423
Arduino ESP32 Core support of ESP-IDF 5.1 (for ESP32-C6) is however still a work in progress:

1 week ago @meatpiHQ Will your upcoming "WiCAN Pro" next-generation adapter not be based on the "ESP32-C6" SoC?
If not when wondering if you at least consider using an ESP32-C6 in your upcoming ESPNetLink LTE/GPS adapter?
Reasons for the request is that the ESP32-C6 has Wi-Fi 6 and BLE 5 support as well as an 802.15.4 radio for Thread or Zigbee:

1 week ago Hey @Hedda
I really wanted to use the C6, but it did not have what it takes, especially the USB host and the PSRAM.
What I really want to do is use the P4 with the C6. That would be the perfect combination. And I might still release a new version for C6 but without crowd funding just to see how well it performs.
Unfortunately the ESPNetlink is also based on the S3 :)
Btw you should check the WiCAN latest firmware update, now the integration with home assistant is easier than ever.
https://github.com/meatpiHQ/wican-fw?tab=readme-ov-file#home-assistant
Suggest looking into if possible to replace ESP32-C3 SoC with ESP32-C6 in next-generation of WiCAN hardware for the future.

Note! The official Espressif ESP-IDF v5.1, which is currently still in development, will include initial support for the new ESP32-C6 chip, however, while Espressif ESP-IDF v5.1 has not yet been released it should mostly work if using the master branch in esp-idf repository. If you want to track the development status then follow these the updates made to these other issues for ESP32-C6:

ESP32-C6-WROOM-1 module is already available on Aliexpress at $14.25(US) for a pack of 5 modules (lower price if buy in bulk).
The main reason to use ESP32-C6 instead of ESP32-C3 is that it should be more future proof because it supports more modern interfaces yet it should be backwards compatible while remaining competitive in price so should not raising total cost of the product my much, at least not compared to the added value for that small additional sum.
ESP32-C6-WROOM-1 radio module has ESP32-C6 single-core 32-bit RISC-V clocked up to 160 MHz 320KB ROM, 512KB SRAM, low-power RISC-V core @ up to 20 MHz Wireless – 2.4 GHz WiFi 6, Bluetooth 5.0 LE, 802.15.4 radio for Zigbee 3.0 and Thread. Matter compatible. PCB antenna, 8MB SPI flash.
As an IoT (Internet-of-Things) device it would great if could enable basic capability over Thread via the new Matter standard for IoT:
https://en.wikipedia.org/wiki/Matter_(standard)
Obviously, the initial Matter 1.0 standard is rather limited so mostly just hype now but future versions of the standard do have potential.
https://csa-iot.org/all-solutions/matter/
For example; as of right now version 2.0 of the Matter specification is expected to be published in March or April 2024 so progress is moving relatively fast now in extending the capability to expose new device types (clusters) and more attributes in future versions.
