Mini USB UART FTDI Programmer 3.3/5V USB Serial

This breakout board carries an FT232 compatible chip that provides a connection from USB to serial. This programming adapter is not needed on an Arduino Uno, but ESP8266, Sonoff or Arduino Pro Mini need it for programming. A jumper switches between 3.3 V and 5 V logic. DTR instead of RTS is routed to the pin header, which allows the microcontroller to reset automatically after uploading.

Recommended alternative with 1.8 V, 3.3 V and 5 V: FT232 USB to TTL Module

Recommended Accessories:

• Mini USB Cable black 0.5m
• Dupont Cable 6*P 20cm

Features:

• Jumper for 3.3 V or 5 V logic
• LEDs for power, RX and TX
• Pin header: DTR, RX, TX, VCC, CTS, GND
• Further signals on solder points: DCD, DSR, RI, RTS, PWREN, SLEEP, RXL, TXL
• Not an original FTDI chip: according to customer feedback, the modules have the same serial number and an EEPROM that cannot be written

Application Examples:

• Programming ESP8266, Sonoff and Arduino Pro Mini
• Serial connection between PC and microcontroller
