My services have already helped…



Here’s what my customers have to say…

We had Opsero design and build a complex controller board for us using the Zynq 70z20 dual ARM core with FPGA and multiple special analog features DAC’s, ADC’s programmable I/O supplies etc. Jeff had good knowledge and understood well what we were trying to accomplish. We used his experience with the chip to help us determine best paths for the design. His communication with my team was top notch and he stayed on top of the job during a long trip he had long planned, allowing us to keep on schedule. We would highly recommend him and will use him on future projects.
