The backorder for the I/O expander is estimated at around 80 weeks ( https://lcsc.com/product-detail/I-O-Expanders_Microchip-Tech-MCP23017-E-SO_C47023.html ) // Are their alternative chips? I noticed the same issue with the ARM chip. The 71 ( Version that doesn't have its own crystal ) is available a bit of everywhere but the 72 used in the version 0.2 is a bit on the rare side.
So are their alternatives for the I/O expander?
