RF-NANO (Arduino Nano + NRF24L01 combine)
I just bought this RF-NANO from AliExpress for S$4.79 (during sales). Basically it is an Arduino Nano (ATmega328P) combine with NRF24L01 in single board, plus built in antenna. I though great 😍, that should considerably reduce receiver weight. Unfortunately there is no unsoldered version, so I have to remove pin manually to reduce weight further. Everything work fine, except for the NRF24L01, it is unable to communicate 😱. I'm using the same proven working code 😉. I suspect either the chip broken or CE and CSN connected differently. As usual there is no information at the seller page 😨. I cannot even message the seller, somehow it does not have messaging icon 😵. Luckily I found the schematic from google. Based on the schematic CE is connected to D10 and CSN is connected to D9 which is the opposite on my code. Made little modification and everything work 😁. But I will still put maybe 2 star because seller un contactable and there is no connection description on the seller pa
