PL2303/USB to TTL upgrade small board with nine upgrade lines, flashing and automatic reset

Scope of application

1). USB to TTL, serial communication

2) . Arduino board download program

3) 51 microcontroller download program

Product features

1). The module comes with a 500MA self recovery insurance to protect the computer's USB port

2). Equipped with an automatic reset port, there is no need to manually reset Arduino when programming

3). Stable transmission, supporting baud rates up to 1.2M

Instructions for use

1). When converting from regular USB to serial port, only VCC needs to be connected, GND，RXD，TXD

2). When programming Arduino, connect VCC, GND, RXD to the TXD of the Arduino board, TXD to the RXD of the Arduino board, and RST to the RST (reset port) of the Arduino board

Matters needing attention

1) The output current of the 3V power port should not exceed 100MA, otherwise it may cause unstable communication or even damage the module
