Hi there,
What options do I have for using two UART devices with a particle boron? I have found this repo with a custom board GitHub - rickkas7/SC16IS740RK: Interface to SC16IS740 UART for Particle devices that I can make with JLC or something. But, I’m wondering if there’s an off the shelf board I can make to use SPI/I2C as another serial port.
Thank you!
