Beagle USB 12 - Low/Full Speed USB Protocol Analyzer + Sticker [discontinued] _RPI_HAT_PortExpand Since these are nearly identical

Since these are nearly identical in how they work to the 36mm pixels

4" TFT display with a resistive touchscreen and a 2 x 20 female socket header

but any 3–5V microcontroller with a UART can communicate by sending and receiving commands over the RX/TX pins

the red and green LEDs will blink when data is transmitted/received by the FTDI chip

USB and LiPo battery powered

Reverse engineering a USB device? You will fall in love with the Beagle 12 USB Analyzer. This hardware analyzer is completely non intrusive, and is much better than flaky software analyzers. Perfect for when a problem is bad enough it crashes the USB host, or for real time data capture analysis. We used the big sister version (the Beagle 480) for our famous Open Kinect reverse engineering
