PMOD to Qwiic Adapter
The adapter has two Qwiic/Stemma QT connectors. You can use it as a part of a daisy-chain: connect one of the connectors to the Host or a different Peripheral board, and the other connector to another Peripheral board to continue the chain. You can use either connector for either purpose; there is no direction of signals.
The easiest way to mount it is to use the extra-long headers supplied with the Adapter. Just make sure to align the board properly.
The KiCad hardware source files for the board can be found on Github.
