Multi-processor AI development board with STM32MP157-class MPU, RP2350/RP2040 companion MCU, ESP32-S3 WiFi/BT, DDR3L, storage, Ethernet, display/camera/audio, USB-C PD/DC power, and 100 mm x 72 mm 4-layer PCB target.

this is a custom board using the MCU "STM32F107RBTx". the reason why i chose this MCU is because i wanted to implement circuits for ethernet communication, CAN communication and USB communication.

CNC hydraulic press brake controller with STM32H743, ADS1256, 5x DAC8501 ±10V outputs, 3x AD598 LVDT interfaces, isolated 24V digital inputs, 100BASE-TX Ethernet, watchdog, E-stop hardware disable, and 4-layer 220mm x 160mm PCB architecture. Domains: field 24V I/O, precision analog, logic/Ethernet. Safety behavior: E-stop and valve-disable force all analog command outputs to 0V-safe state and disable field enables; watchdog and power-good supervisor reset MCU on comms or rail faults. PCB constraints: L1/L4 signal+components, L2 solid GND, L3 power plane, 1.0mm board inset margin, RJ45 at edge, field connectors on opposite edge, isolation corridor between field wiring and logic/Ethernet, 4x M4 plated mounting holes inset 10mm from corners.
