Microduino-Module USBTTL

Language:	English  • 中文

Microduino-FT232R Microduino-USBTTL is based on FDTI FT232RL chip (Arduino embedded driver). It can be stacked with Microduino-Core or Microduino-Core+, enable Microduino core modules to communicate with PC.

Features Specification The USBTTL is an interface conversion chip, which can achieve the conversion from USB to the serial UART interface or to the synchronous/asynchronous Bit-Bang interface mode. FTDI provides driving programs under all kinds of operation systems. Microduino-USBTTL is arduino compatible with simple design, easy to use. Integrate EEPROM, which can be used in IO configuration or saving USB VID serial number and production description information. Integrate electrical level converter, making its I/O level support 5V-2.8V voltage range. With high driving ability of the I/O pin, it can drive multiple devices. With a power-on reset circuit and a supply decoupling RC circuit integrated inside, the chip can generate clock function automatically and needs no extra crystal oscillator, saving costs. Conform to RoHS standard. Microduino-FT232R-Pinout

Applications The USB2TTL datasheet at DS_FT232R says you can draw up to 50 mA from the FT232R 3.3V output.

FQA Can the external power work with Microduino-USBTTL for power supply? • Since the current of USBTTL is small (less than 100ma), we don't suggest using them together. You can only use USBTTL during the testing phase and are allowed to use the external power supply after finishing the program debugging. The PC can't identify the FT232 module which worked well previously. The solution for FT232R (USBTTL) error "FT232R USB UART"
