Yp-05 Schematic May 2026

Receive Data; connects to the TX pin of the target microcontroller.

Integrated 500mA self-restoring fuse for USB power over-current protection. Yp-05 Schematic

Transmit Data; connects to the RX pin of the target microcontroller. Power output; provides 3.3V or 5V to the target device. CTS Clear to Send; used for hardware flow control. GND Common ground for the circuit. Common Use Cases Receive Data; connects to the TX pin of

Since the ESP32-CAM lacks a built-in USB port, the YP-05 is frequently used to flash firmware. This requires connecting U0R (RX) to TX , U0T (TX) to RX , and bridging GPIO0 to GND to enter flashing mode. Power output; provides 3

Dual voltage capability supporting both 3.3V and 5V logic levels, typically selectable via a jumper.

The YP-05 is designed for versatility and ease of use in breadboard projects or embedded system debugging: FTDI FT232RL (or compatible clones).

Data Terminal Ready; used to auto-reset microcontrollers (like Arduino) for programming.
