Microduino FT232R

Microduino-FT232R is a USB to serial UART interface module, it is based on FDTI FT232RL chip (Arduino embedded driver). Microduino-FT232R can be stacked with Microduino-Core or Microduino-Core+, enable Microduino core modules communicating with PC.

The FT232R has optional clock generator output, and the new FTDIChip-ID? security dongle feature. In addition, asynchronous and synchronous bit bang interface modes are available.

USB to serial designs using the FT232R is simplified by fully integrating the external EEPROM, clock circuit and USB resistors onto the device.

Features:

•     Microduino USB2TTL module, connecting PC with Microduino, uploading program to Core/Core+.
•     Main chip: FT232RL
•     UPin-27: Microduino standard interface
•     The Microduino-FT232R is a USB to serial UART interface with optional clock generator output, asynchronous and synchronous bit bang interface modes are available.
•     The Microduino-FT232R adds two new functions compared with its predecessors, effectively making it a "3-in-1" chip for some application areas. The internally generated clock (6MHz, 12MHz, 24MHz, and 48MHz) can be brought out of the device and used to drive a microcontroller or external logic. A unique number (the FTDIChip-ID?) is burnt into the device during manufacture and is readable over USB, thus forming the basis of a security dongle which can be used to protect designers' application software from being copied.
•     Using the U-Shape 27-pin interface (UPin-27), the standard interface of Microduino, all Microduino modules and sensors can be easily stacked and extended through it
