Converter Board

Product Details:

The CP2102 is a highly-integrated USB-to-UART Bridge Controller providing a simple solution for updating RS-232designs to USB using a minimum of components and PCB space. The CP2102 includes a USB 2.0 full-speed function controller, USB transceiver, oscillator, EEPROM, and asynchronous serial data bus (UART) with full modem control signals in a compact 5 x 5 mm MLP-28 package.The CP2102 UART interface implements all RS-232 signals, including control and handshaking signals, so existing system firmware does not need to be modified. In many existing RS-232 designs, all that is required to update the design from RS-232 to USB is to replace the RS-232 level-translator with the CP2102.

Description: This is a simple to use USB to Serial Converter. It outputs RS232 level signals on the TX and the RX line. Unlike the cheap converters available in the market, which rarely work, if at all, this converter is highly reliable and can be used on all major operating systems, computers and laptops.

This converter is USB powered and needs no external power. It can provide the USB port''s 5V power supply to an external circuit.You can also get TTL level RX and TX signals from the header pins on the board. The board has standard 3 mm mounting holes for easy mounting.
When connected to USB port this converter sets up a virtual serial port which can be used and interfaced just like any normal serial port. You can use this board with all our development boards to do serial communication through USB. You can also program our development boards, which support serial bootloading, through USB using this converter.

This USB to Serial converter uses the popular CP2102 IC from Silicon Labs for the USB conversion. This board can be used on all major operating systems.

Product Details:

This particular module is suitable for tutorial use and perhaps for some hobbyists. Its drawback is that its I2C address is hard-wired to all zeros. (Note that I2C is a very effective 2-wire communications standard that is used by many small semiconductor devices such as microcontrollers and sensor peripherals.) If the address lines could be jumpered high or low, then several identical modules could be placed on the same I2C lines. I would therefore recommend the alternative module named the Mini PCF8591 AD DA Shell Module because it has that capability. It is also at least three times the price.

The IC permits only 8 bit data allowing only 256 steps in the analog output value or the digital output value. This is likely borderline for hobbyists who may want to build instrumentation or test equipment.

My tests show another frustration: A lower than expected analog output voltage. For a 4.88 volt supply the output is only 4.17 volts (85%) at maximum value setting. Since the maximum supply voltage is 8 volts, increasing the supply to 6 volts may get a 5 volt result. I did not remove the green LED and related resistor to see if the problem was simply an excess current drain from the ICs AOUT.

Reference: PCF8591 8-bit A/D and D/A converter Product Specification, 2003-01-27, Philips Semiconductor.

The module is composed of:

• A PCF8591 IC at U1.
• A thermistor that measures temperature at R6.
• A photo-voltaic cell. This is a light sensitive resistor at R7.
• A single turn trimmer potentiometer at R3.
• Two LEDs: a red one that is on when the device has power; and a green one that increases brightness as the output voltage increases.
• Three red jumpers that apply the voltage sources  photo-voltaic cell, thermistor, and potentiometer, and to analog input channels AIN0, AIN1, and AIN3 respectively.
• Connector pins for I2C (SDA and SCL), Vcc, and ground.
• Connector pins for the Analog output AOUT, and pins for each of the three analog input channels.
• A 4-wire ribbon cable is included with sockets suitable for the connector pins.

Product Details:

The level converter is very easy to use. The board needs to be powered from the two voltages sources (high voltage and low voltage) that your system is using. High voltage (5V for example) to the HV'' pin, low voltage (3.3V for example) to LV'', and ground from the system to the GND pin.

Features:

• Connects a 3.3V device to a 5V system
• Steps down 5V signals to 3.3V AND steps up 3.3V to 5V simultaneously
• This level converter also works with 2.8V and 1.8V devices.
• Sets high and low voltages and step up and down on the same channel
• Each level converter has the capability of converting 4 pins on the high side to 4 pins on the low side with two inputs and two outputs provided for each side.
