This is a hot swappable 3.
ZEUS user manual PC/104 interface The ZEUS PC/104 interface is emulated from the PXA270 PC card interface to support 8/16 bit ISA bus style signals. As the interface is an emulation, the ZEUS does not support some PC/104 features. Please refer to the section Unsupported PC/104 interface features on page 40 for specific details. Add-on boards can be stacked via the PC/104 interface to enhance the functionality of the ZEUS.
Detailed hardware description PC/104 interrupts The PC/104 interrupts are combined together so that any interrupt generated on the PC/104 interface generates a single interrupt on the GPIO17 pin of the PXA270 processor. Reading the PC104_IRQ register located at the address 0x12800000 can identify the PC/104 interrupting source. The registers indicate the status of the interrupt lines at the time the register is read. The relevant interrupt has its corresponding bit set to ‘1’.
ZEUS user manual Unsupported PC/104 interface features The ZEUS does not support the following PC/104 bus features: • PC/104 IRQ9, IRQ14 and IRQ15 are not available. • DMA is not supported. Therefore, AEN signal is set to a constant logical zero. • Bus mastering is not supported. Therefore, do not connect any other master add-on board to the ZEUS PC/104 interface. • Shared interrupts are not supported. Do not connect more than one add-on board to the same interrupt signal line.
Detailed hardware description TFT panel data bit mapping to the ZEUS The PXA270 can directly interface to 18-bit displays, but from a performance point of view it is better to use 16-bit only. 18-bit operation requires twice the bandwidth of 16-bit operation.

ZEUS user manual Appendix B - Mechanical diagram All dimensions are shown in mm.
Appendix B - Mechanical diagram When mounting the ZEUS use only M3 (metric) or 4-40 (Imperial) screws. The mounting pad is 6.35mm (0.25") and the hole is 3.175mm (0.125"), so ensure any washers fitted are smaller than the pad. Using oversized screws and washers, or tooth locking washers, can cause short circuits and over-voltage conditions. We recommend that you use a Loctite screw thread lock or a similar product over tooth locking washers.
