SparkFun FTDI Basic Breakout - 3.3V

 Ean: 0799430213394   |    PartNumber: DEV-09873A   |   Asin: B004G52QR0

This is the newest revision of our FTDI Basic. We now use a SMD 6-pin header on the bottom, which makes it smaller and more compact. Functionality has remained the same. This is a basic breakout board for the FTDI FT232RL USB to serial IC. The pinout of this board matches the FTDI cable to work with official Arduino and cloned 3.3V Arduino boards. It can also be used for general serial applications. The major difference with this board is that it brings out the DTR pin as opposed to the RTS pin of the FTDI cable. The DTR pin allows an Arduino target to auto-reset when a new Sketch is downloaded. This is a really nice feature to have and allows a sketch to be downloaded without having to hit the reset button. This board will auto reset any Arduino board that has the reset pin brought out to a 6-pin connector.

Raspberry Pi HAT - 32 I/O Port Expander - MCP23017 - I2C - Black

Model: HAT32IOPE   |    Mpn: HAT32IOPEB   |    Ean: 0648260628239   |    PartNumber: HAT32IOPEB   |   Asin: B01MYD2QTP

The Raspberry PI HAT - 32 I/O Ports Expander (HAT32IOPE) board is a 32 Input/Output digital expansion board designed for use on the Raspberry Pi A+, Raspberry Pi B+, Raspberry Pi 2 Model B, and Raspberry Pi 3 Model B. The board use two Microchip MCP23017 16-bit I/O expander, allowing you to connect up to 32 digital inputs or outputs to the Raspberry Pi. The HAT32IOPE is connected to Raspberry Pi using a 20x2 GPIO connector with extended pins that allow you to stack many extension boards in a single Raspberry Pi. You can select the I2C address using the on-board 3bits switches (ON=0 the pin is grounded, OFF=1 the pin is pull up to 5V). The MCP23017 supports up to 8 different I2C: Due to there are two MCP23017 per board you are allowed to stack up to four HAT32IOPE boards on a single Raspberry Pi for a maximum of 128 I/O ports. The right angle headers allow you to connect the I/Os while the boards are stacked. The HAT32IOPE may be powered thru a 5V input polarized male connector (now on a right angle connector, female cable to connect external supply included) or thru the Raspberry Pi GPIO 5V pins. If you use the first option you can power the Raspberry Pi shorting the "Back PWR" jumper or isolate the Pi and HAT32IOPE keeping it open. In order to power the HAT32IOPE thru the Raspberry Pi GPIO 5V pins the "Back PWR" jumper must be shorted. Use of an external supply is recommended when you connect more than one HAT32IOPE boards to your Raspberry Pi. Specifications: -Vdd (5V polarized input header without BACK PWR): 4.5V - 5.5V -All digital inputs and outputs: 0 - Vdd -Maximum current on a single I/O Pin (sourced or sunk): 25 mA -Maximum current on each MCP23017 chip: 125 mA

Features

  • 32 Digital Inputs/Outputs, based on the Microchip MCP23017 chip
  • Control via the Raspberry Pi I2C port, selectable I2C addresses thru switches
  • Stackable, up to 4 boards per Raspberry Pi, right angled headers for ease connection when stacked
  • All I/Os are 5V tolerant, built in 3.3V to 5V shifter for Raspberry Pi I2C port protection
  • Raspberry Pi can be Back Powered or isolated thru a jumper, The board can be powered thru the Raspberry Pi GPIO 5V pins, or thru a 5V polarized input header from an external supply

Raspberry Pi HAT - 8 Channel ADC - MCP3208 - SPI - Kit Edition

Model: HAT8ADCK   |    Mpn: HAT8ADCK   |    Ean: 0648260628253   |    PartNumber: HAT8ADCK   |   Asin: B06Y576DCH

The Raspberry PI HAT - 8 Channel ADC (HAT8ADCK) is an 8 channel 12 bit analogue to digital converter with SPI serial interface, designed to work with the Raspberry Pi A+, Raspberry Pi B+, Raspberry Pi 2 Model B, and Raspberry Pi 3 Model B. This is a kit edition, in order to solder it, you only need a soldering iron and tin. The HAT8ADCK is based on Microchip MCP3208 A/D converter chip, containing 8 analogue inputs and use the SPI interface to communicate with the Raspberry Pi. The HAT8ADCK was designed to work as a single ended A/D converter. The HAT8ADCK has four options for reference voltage. Using the 12 bits Microchip MCP3208 chip, the range from cero to the voltage reference can be divided in 4095 spaces so you can obtain different resolutions when change the voltage reference. The HAT8ADCK may be powered thru a 5V input polarized male connector (female cable to connect external supply included) or thru the Raspberry Pi GPIO 5V pins. If you use the first option you can power the Raspberry Pi shorting the "Back PWR" jumper or isolate the Pi and the HAT8ADCK keeping it open. In order to power the HAT8ADCK thru the Raspberry Pi GPIO 5V pins the "Back PWR" jumper must be shorted. The extended pins on the GPIO connector allow you to stack the HAT8ADC along with other expansion boards. The right angle headers allow you to connect the Inputs while the boards are stacked. You can use up to 2 HAT8ADCK stacked in a single Raspberry Pi, for a total of 16 inputs, due to the SPI interface has only two CE pins on GPIO. You can choose from CE0 and CE1 using the corresponding jumper on the board. The MCP3208 chip is capable of conversion rates of up to 100 ksps (kilo samples per second). Specifications -Vdd (5V polarized input header without BACK PWR): 4.5V - 5.5V -All analog inputs: 0 - Vref -Low current operation with typical standby and active currents of only 500 nA and 320 A, respectively -Unused inputs should be tied to ground -Conversion rate at Vdd=5V: up to 100 ksps

Features

  • 8 Analog Inputs, based on the Microchip MCP3208 chip
  • Control via the Raspberry Pi SPI interface, selectable CE addresses thru a jumper
  • Stackable, up to 2 boards per Raspberry Pi, right angled headers for ease connection when stacked
  • Built in 3.3V to 5V shifter for Raspberry Pi SPI port protection,
