The quality is okay. The connector is spring-loaded. Delivery takes a couple of weeks to St. Petersburg. The pricing for these adapters is unclear - for SPI it's cheap, for SDIO it's five times more expensive. Are the connectors the same, are they charging extra for a couple of extra tracks or for 5 0603 resistors?

Fast delivery. A simple and useful adapter, ideal for the w806 microcontroller.

Everything ok

As described :-) 14 days to austria :-)
