I think it is a very nice product set. The prices are very good considering these features. You get an experimental set for almost the price of one module. The node and gateway prices are also excellent. I think the only thing missing is the promotion. Also a suggestion. For example, esp32s3fn8, where the Arduino ide, esp idf and microphyton programming infrastructure are preserved, can be added to this board. In this way, while the target audience of the board will increase, wifi and bluetooth will also be added to the system. Also, since it is controlled with at commands, the more affordable RA01SH can be used instead of the MCU-equipped RA08H. My humble opinion.
