Hihdl 0 Posted February 13, 2017 Share Posted February 13, 2017 I have bread boarded two Nano modules both have their own NRF24L0 radio. Both boards work perfectly when attached to a computer USB/power port. Both talk back and forth sending and receiving data. Works great. However if I pull out the USB/power cable from one board and supply 9 volts to Vin .... it won't transmit or receive anymore. I plug the USB/power/communications cable back in and everything is back to normal. I've even used a 120Vac to 5Vdc adapter with a USB output connector and same thing. Won't Transmit/or receive. Any ideas? Link to post Share on other sites
[email protected] 437 Posted February 13, 2017 Share Posted February 13, 2017 @Hihdl, Questions about the nano devices really belong on the Terasic forum. You're more likely to get a Nano engineer on that forum than on this one. That said, were I you, I'd pull up the schematics and look at the power supplies. Are they designed in order to able to handle a 9V battery, or do they need a 5V source? Check your 9V with a voltmeter, does it have the charge you think it does? etc., etc. Dan Link to post Share on other sites
