Last night I received the Attify badge that I ordered. This will allow me to interface with UART, JTAG, SPI, GPIO, and I2C. I plan on doing in depth blog posts for all my steps which I'll publish on https://togetherwehack.com then link here. Also if you'd like to order an Attify badge yourself you can do so here at https://www.attify-store.com/products/attify-badge-assess-security-of-iot-devices?rfsn=1269016.8c1922
