Printed circuit boards (PCB) design

The Grinn company offers its customers a comprehensive design of printed circuit boards (PCB). We design circuits from simple one-sided to high-speed multilayer. Our advantage, as opposed to competition, is the high quality of offered solutions for the price. We design printed circuit board of digital circuits, analog and RF.

Microcontrollers

Grinn company offers high-quality solutions in embedded systems with particular emphasis on microcontrollers 8, 16, 32-bits (C51, PIC, AVR, AVR32, MSP, ST7, ARM7, ARM9, ARM Cortex-M3) and DSP (Texas Instruments, Analog Devices). We create complete solutions, starting from concept, through design printed circuit board and program, ending with the production and implementation of the finished product. With years of experience, design team implement real-time systems based on Linux operating system. We deliver comprehensive solutions that flexibly adapt to the needs of our clients.
