Product Introduction Development board is a circuit board used for embedded system development, including a series of hardware components such as a central processing unit, memory, input devices, output devices, data paths/buses, and external resource interfaces. The TTL level is 3.3V and includes three status indicator lights. This module comes with a 5V to 3.3V power supply IC instead of a diode voltage reduction scheme!

product size is 16mm*25mm. This module comes with a 5V to 3.3V power supply IC instead of a diode voltage reduction scheme. The TTL level is 3.3V and includes three status indicator lights. A development board is a circuit board used for embedded system development, including a series of hardware components such as a central processing unit, memory, input devices, output devices, data paths/buses, and external resource interfaces. The FS-UTTL-340N module adopts the new generation CH340N chip, which can convert USB to 3.3V TTL for serial communication and microcontroller download. The module comes with a 5V to 3.3V power supply IC, which can provide a 5V/3.3V voltage output.
