SPL06-001

LPS22HB ↔ SPL06-001

LPS22HB (ST): 260-1260hPa absolute, 24-bit ADC, I2C/SPI, 10-pin HLGA (2x2mm), embedded 32-slot FIFO, digital LPF (ODR/9 or ODR/20), pressure noise 0.0075hPa RMS (high res), I2C addr 0x5C/0x5D, multi-mode (power-down/one-shot/continuous). SPL06-001 (Goermicro): 300-1200hPa, 24-bit, I2C/SPI, QFN-8, FIFO 32-slot, pressure accuracy ±0.5hPa. Отличия: LPS22HB имеет встроенный digital low-pass filter (programmable), SPL06-001 — analog filter only. Operating range: LPS22HB — 260hPa min (для высокогорных приложений), SPL06-001 — 300hPa min. Package: LPS22HB — 2x2x0.76mm HLGA, SPL06-001 — 3.8x3.8mm QFN (крупнее!). I2C address: LPS22HB — 0x5C (SDO=GND) / 0x5D (SDO=VDD), SPL06-001 — 0x76. Pressure noise: LPS22HB — 0.0075hPa RMS, SPL06-001 — ~0.01hPa. Подводный камень: различные register maps и compensation formulas — требуется новый драйвер.
