Hi Ralph,

Nice write-up! It is a cool chip, and handy that it's available in quite a few package sizes, even DIP.

I hadn't realized it had ADC/DAC capability, I've only used it for USB-UART so far. It sounds perfect for a lot of experimentation.

Although that will still be my favourite USB/UART chip, I've recently started looking at the Cypress chips, because there's a feature I miss in the MCP2221, which is hardware flow control pins and sometimes that's needed. Incidentally some of the Cypress chips support built-in I2C too, but don't have the ADC/DAC. The package selection isn't as great either (one is SSOP but all the others are QFN). I'm trying CY7C65213 which is SSOP sized, but doesn't have I2C unfortunately. I hope the drivers etc are good, it's my first attempt at using a Cypress USB-UART chip.

Thanks Ralph,

This seems quite useful. I am about to make an Adafruit order and will get one.
