ZMI Engineering specializes in the design of small embedded microprocessors along with FPGA implementations. Analog and digital design as well as PCB design with low overhead to keep the price $$$ down.
Embedded software and FPGA firmware; Xilinx, Altera, Lattice.
On the right hand side is a picture of the PDT930A main circuit board we designed way back in 1999, it controls the paging data transmitter in the 930 MHz band. It was currently only set for POCSAG alpha and numeric transmission which had full edit messaging. This had limited success as technologies quickly changed in the start of 2000; just after this was designed.
