SMUGDESK FT232RL USB to TTL Serial Module Multi-Level 5V 3.3V 1.8V

SKU CH-8V67-V7EE7

USB-to-TTL converter with FT232RL chip for 5V, 3.3V and 1.8V logic levels

  • FT232RL chip delivers stable USB-to-TTL serial conversion
  • Three logic levels 5V 3.3V 1.8V prevent voltage mismatch damage
  • Compact PCB with clear pins speeds up wiring and debugging
  • Works as firmware burner and serial debug tool for MCUs
  • Compatible with Arduino STM32 and single-chip development projects

USB-to-TTL adapter for embedded development

The module uses an FT232RL chip to convert USB signals into TTL serial data for microcontroller programming and debugging. It targets engineers, students and hobbyists working with Arduino, STM32 or similar single-chip platforms who need a compact tool for firmware flashing and serial monitoring.

Three selectable logic levels cover common MCU

Output can be switched between 5 V, 3.3 V and 1.8 V to match the target device and prevent damage from voltage mismatch. The USB interface limits speed to the FT232RL’s native capability, so very high baud-rate requirements may exceed what this bridge can sustain.

Small PCB with labelled pins simplifies bench wiring

Clear pin markings reduce connection errors during rapid prototyping or lab debugging. The board draws power from the USB port, so no external supply is needed, but the compact layout leaves no room for mounting holes or ruggedised connectors in harsh environments.
