ARM-Based Boards

ARM-based boards (including Cortex-M, Cortex-A and Cortex-R families) are used in advanced control systems, industrial HMIs, IoT gateways and signal-processing equipment. These boards feature complex architectures with DDR memories, high-speed interfaces (Ethernet, USB, PCIe) and real-time or Linux operating systems. Specialized diagnostics cover testing of core and I/O power supplies, inspection of clock and reset signals, analysis of memory buses with advanced oscilloscopes, and software debugging via JTAG or SWD. Professional repairs include replacement of the processor or damaged memories under precise soldering profiles, reconstruction of high-speed signal traces, updating of bootloader and firmware, and functional testing under real processing loads. These services ensure that the ARM board delivers stable performance and high reliability in complex industrial applications after repair.
