So they key factor is hardware & software optimisation for the lowest possible...
Is anyone aware of any of these on the market yet? I know of one, from Insight SIP, but am keen to hear about any others.
(This would save space on the PCB, simplify our...
Using twi_sw_master have discovered that the nrf51422 E00 draws 1.3mA in off mode.
When the twi device is removed from the bus, the nrf51422 draws under 5uA in off mode...
I want to merge soft device, application and boot loader in order to improve efficiency for factory. I searched relative topics in this forum and found something useful. At...
We have been unable to establish a link between a Garmin HR monitor over the air, we have established USB comms to a cell phone device. We took the transmission line directly...
i find one related question:
