    Well packaged and excellent delivery time (13 calendar days from order). This is an interesting module combining independently programmed RP2040 and ESPC3 chips. There is no defined way of communicating between the chips although I have some ideas on this. It also seems to view the RP2040 as the main chip and the C3 as just there to give some sort of network connectivity. I would have preferred to see the ESP take the main role with the RP2040 used as a co-processor, or, even better, give both processors access to a shared address space. Regardless of all this, I don't think this module is suitable for general hobbyist use or the typical or the typical Arduino programmer. For specialist use though, it offers some intriguing possibilities and I look forward to some enjoyable hacking in the weeks ahead!

    Well packaged and pretty good delivery time (15 calendar days from order). This board has the interesting idea of putting both a C3 and an rp2040 on a singer board, together with an LCD, What is not clear (to me at least) is how or whether the two chips can communicate. I am still exploring this. In the meantime, the board is good value when treated as a stand-alone C3 *OR* RP2040 with an LCD so I am happy to recommend it for experimentation purposes. ,

    the product is good but the document about how to use is bad.

    Great device. I believe that the design with the RP2040 as the primary MCU is the way go. The ESP32 works great as wireless networking co-processor communicating using AT command set, even for MQTT. I run Python on the RP2040 which provides a deterministic response, especially with state-machine based IO programming, making it ideal for real time control processing. You can't do that on the ESP32, which runs Python as a switched process under RTOS and only provides software interrupts. And on top of all that a great display that now works seamlessly with micro Python on the 2040. Once you get the framework right a great unit for hobbyists who want to use Python, have super fast real-time responses, a built in display and super easy Wi-Fi and BT connectivity. .
