Hi Guys,
I have just launched my Kickstarter campaign
https://www.kickstarter.com/projects/1673888854/adc-dac-and-gpio-universal-raspberry-i-o-hat-8-porMy hat is a All-In-One 8 port ADC/DAC/GPIO hat for Raspberry Pi.
- up to 8 analog 12 bit inputs (ADC)
- up to 8 analog 12 bit outputs (DAC)
- up to 8 digital channels (GPIO)
- internal thermometer
- fast 25MHz SPI, 400kSPS ADC
- internal 2.5V (or 2x 2.5V) or external 3.3V ADC & DAC Voltage reference
It is fully
software configurable. Any of the 8 pins can act as ADC (analog input), DAC (analog output) or GPIOs . It is possible create almost any embedded device. Some simple projects like:
• weather station
• voltmeter
• parts tester
• digital thermometer
Using it is possible to:
• control engines
• build robots
• read potentiometers
• read joysticks and dials
• read analog and digital sensors
• provide signals for analog circuits
• act as a digital potentiometer
• read and write any signal (analog or digital)
I quite often need for my Pi projects analog inputs and outputs. On the market I have found only single function slow I2C ADC, DAC and GPIO hats. I needed at least two of them to have both analog outputs and inputs. So I needed to create my own one.
If you think that it is worth sharing let others know.
Regards
Peter
