STM32G4 // CAN-Bus // 4-Layer PCB // Altium Designer // INA240
Architected the "brain" of a decoupled MPPT system, designed to sample solar panel V/I at kHz rates to calculate the Maximum Power Point (MPP) and actuate a high-power Buck-Boost stage.
- Signal Integrity: Designed a professional 4-layer PCB with a dedicated internal solid ground plane to shield sensitive ADC paths from high-current EMI[cite: 228].
- Communication: Encoded optimal power targets into noise-immune CAN-Bus frames to ensure reliable data transmission in switching-noise environments[cite: 59, 296].
- Power Management: Integrated an STM32G4 MCU with an INA240 current sensor and a TPS62177 buck regulator for efficient system-level logic power.
- Performance: Precision tracking logic recaptures 5-15% of energy typically lost to sensor noise in traditional single-board systems[cite: 299].
