Uis8141e | Firmware

UIS8141E_fw_v3.02.bin UIS8141E_fw_v3.01_60fps.bin ⚠️ Do not mix firmware for UIS8141E (ToF) with UIS8141 (IR-only) – they are not interchangeable. Method A – Via USB (if module has onboard USB bridge) Most evaluation modules expose a USB port (FTDI or CH340). The flash is accessible over I2C via USB.
