hello,
I uses NRF51822 to make a beacon with RTC.
When it works initially, the churrent is small about 330uA，but after a few minutes it becomes 1.1mA and stable.
I donn...
Hi,
I'm using CircuitMaker and I tried to import NRF52 reference implementations .PrjPcb files. Unfortunately CircutMaker does not support Altium PCB 6.0 files yet, but...
Hi,
I've recently bought a bluetooth module with a nRF52832 module for my new project (Module: EYSHSNZWZ from Taiyo Yuden). The problem is that I have no experience in embedded...
When I need to implement the functionality of bootloader_secure_ble, I need to produce the micro_ecc_lib_nrf52.lib library file in the following way. Why does not this library...
I'm building home temperature sensor with custom pcb design. I'm using balun( 2450BM14E0003 ) and chip antenna( 2450AT42B100 ) from Johanson Technology. Beacon works and it...
