People have used JITX to design a wide variety of circuit boards. Here are some designs that we have permission to share (shareable projects are mostly skewed towards research applications).
One of the first designs was a prototype instrument for a novel hazardous materials sensor, using a BeagleBone attached to custom signal driver and data interfaces.
Another simple design to allow a Raspberry Pi to control a 1/16 scale RC car using a camera and off-board servo motors. Board includes a high-side power switch and a high-quality 5V supply for the Raspberry Pi.
A reliable power sensing and control board to manage the power rails for sensing, actuation, and compute in an autonomous truck.
A design with many finely adjustable, low noise power supplies and clock sources for testing novel integrated circuits. Included detailed voltage and current sensing for each rail.
A desktop Silicon validation fixture to test a new process for integrating chiplets on a Silicon Interposer. Imported wirebond pinout and generated much of the design automatically. Included clock fanout for on/off board high-speed clocks.
A similar design to the above validation board, but instead of having ~400 bond wires, this version has a 0.3mm pitch ~2500 pin BGA version of the device under test. ~5000 micro-vias were automatically generated in an inverted pyramid pattern to escape signals from the device.
A small board using an nRF528342 BLE SoC, that includes battery charging, an accelerometer and a 6-channel AFE.
A brushless motor driver using field-oriented control to squeeze the best performance out of CoTS torque-dense motors.
