choosing USB-GPIO for radio and accessory control
Hi all,
I would like to try and use the 5V outputs from a GPIO to switch the
relays in a band-pass filter[1] and maybe other things like PTT control.
Has anybody tried any of the USB-GPIO modules for their desktop/laptop,
especially those that work with Debian or other Linux distributions?
Search engines find a few possibilities:
- crowdfunded RTk.GPIO[2], £11.99, aims to have the same pin-out and API
as the Raspberry Pi
- Adafruit FT232H Breakout[3] - General Purpose USB to GPIO+SPI+I2C, $14.95
- Numato Lab 8 channel USB GPIO[4] - $19.95 (screw terminals on this one)
- eBay has generic[5] devices for £1.05
Has anybody tried any of them? Can anybody suggest others?
Regards,
Daniel
